Scenario 1 Vision Practitioner

How do you set product vision when AI is changing the market quarterly?

What the interviewer is testing: Whether your vision anchors on durable customer problems.

Model answer, red flags and follow-up

A strong answer

I anchor the vision on a durable customer problem, something that will still be true in five years whatever models exist. "Help every small business owner understand their cash position without an accountant" survives any technology shift. "Be the leading AI-first platform" does not, because it describes a tool rather than a purpose.

AI then changes the how. So the vision stays stable while strategy and bets get reviewed more often, usually quarterly, against what the latest capabilities make newly possible or newly threatening. I keep a short list of questions that each review must answer: what got cheaper or better, what did a competitor ship, and which of our assumptions broke.

The signal I watch is churn in the vision itself. If I am rewriting it every quarter, I have confused strategy with vision, and teams lose the stable direction they need to make local decisions.

Answers that lose you the room

  • Tying the vision to a technology
  • Rewriting it every quarter

Expect this follow-up: How often do you revisit strategy?

Scenario 2 Org Design Advanced

Would you centralise ML talent or embed it in product teams?

What the interviewer is testing: Whether you design AI talent structure for capability and ownership.

Model answer, red flags and follow-up

A strong answer

I start from the stage of the company's AI journey. Early on, I prefer a central group because it concentrates scarce talent, builds shared infrastructure, sets standards for evaluation and data handling, and avoids five teams solving the same problem five ways. A central team is also easier to hire for, since strong ML people want to work with peers.

As use cases mature and product teams develop real AI fluency, I embed engineers into those teams so they sit close to the customer problem and ship faster. The central group then shrinks into a platform and standards function.

Whichever shape I choose, I insist on a named owner for data quality and for evaluations. Without one, quality drifts and everyone assumes someone else is checking.

I change the model when I see symptoms: central queues becoming a bottleneck means embed more, while duplicated tooling and inconsistent quality means pull standards back to the centre.

Answers that lose you the room

  • Choosing a model by fashion
  • No owner for data and evals

Expect this follow-up: When would you change from central to embedded?

Scenario 3 Operating Model Advanced

How would you move a project-driven organisation to a product operating model?

What the interviewer is testing: Whether you can drive operating-model change beyond slides.

Model answer, red flags and follow-up

A strong answer

I do not announce a transformation. I pick two or three teams with willing leaders and run them as real product teams: persistent ownership of an area instead of a project that disbands, goals expressed as outcomes, and funding attached to the team rather than approved project by project.

Those teams become the proof. I use their results, including their early mistakes, to show the rest of the organisation what changes in practice.

The hardest part is leadership behaviour, so I address it deliberately. Executives are used to asking "is it on time?" I coach them to ask "did the outcome move, and what did we learn?" in reviews. I also change the funding conversation with finance, because annual project budgets will quietly pull everything back to the old model.

I avoid renaming roles first. Calling project managers "product owners" without changing decision rights is the most common way this transition fails.

Answers that lose you the room

  • Renaming roles only
  • Skipping executive habits

Expect this follow-up: What would you change first at the leadership level?

Scenario 4 Board Pressure Advanced

The board wants an AI strategy in 90 days. What do you present?

What the interviewer is testing: Whether you give the board a focused, evidence-based AI view.

Model answer, red flags and follow-up

A strong answer

I would not bring a list of pilots, because boards cannot judge or act on that. I would bring a focused point of view in five parts.

First, where AI creates real customer value for us, backed by evidence from customer conversations and usage data. Second, where it threatens our position, including which competitors or new entrants could erode our advantage and how quickly. Third, a small set of prioritised bets, perhaps three, each with an owner, a success metric, an investment level and a decision date. Fourth, the honest gaps in data, talent and infrastructure that limit what we can do. Fifth, our risk posture: what we will not do, how we handle safety, privacy and regulation, and who is accountable.

I would also show what we are deliberately leaving out and why. Boards trust a plan more when the constraints are visible.

Answers that lose you the room

  • Presenting a list of pilots
  • Ignoring risk and data gaps

Expect this follow-up: What would you leave out of the plan?

Scenario 5 Measuring Product Practitioner

How do you measure the effectiveness of a product organisation?

What the interviewer is testing: Whether you measure product outcomes and learning.

Model answer, red flags and follow-up

A strong answer

I measure whether the organisation is producing outcomes and learning, not whether it is busy. My core set is four things.

Outcome delivery: progress against the company outcomes the strategy depends on, not feature counts. Decision speed: how long it takes from a question to a committed decision, since slow decisions are a hidden tax. Discovery quality: how many bets were framed with a hypothesis and evidence before engineering began. Team health: engagement, attrition and the quality of manager relationships, because unhealthy teams stop learning.

One signal I weight heavily is how often we stop a bet on evidence. If nothing is ever stopped, either we are not testing hard enough or we are hiding failures. A healthy product organisation kills weak ideas early and says so openly.

I avoid counting features shipped because it rewards output and encourages teams to ship things nobody needs.

Answers that lose you the room

  • Counting features shipped
  • Ignoring team health

Expect this follow-up: What tells you a team is learning?

Scenario 6 Talent Practitioner

What skills do PMs need for AI products, and how do you build them?

What the interviewer is testing: Whether you build AI skills through practice.

Model answer, red flags and follow-up

A strong answer

Beyond core product judgment, AI products need a specific set of additions. Data literacy, so PMs can ask whether the data supports the use case. Evaluation thinking, meaning they can define what "good" looks like and build a test set before anyone argues about quality. Comfort with uncertainty, because model behaviour is probabilistic and roadmaps need learning milestones rather than fixed dates. And cost awareness, because every request has a marginal cost that can wreck margins at scale.

I build these skills through practice rather than courses. PMs pair with ML leads on a live project, work from a shared playbook for evals and launch criteria, and review real failures together. I run internal clinics where a PM brings an eval design for critique.

I check the result by watching whether PMs bring eval sets and cost estimates into their proposals unprompted. That tells me the skill has become habit.

Answers that lose you the room

  • Sending everyone on a course
  • Ignoring cost awareness

Expect this follow-up: How do you build eval thinking in PMs?

Scenario 7 Short vs Long Advanced

How do you balance quarterly revenue pressure against long-term bets?

What the interviewer is testing: Whether you balance short and long bets explicitly.

Model answer, red flags and follow-up

A strong answer

I make the trade-off explicit instead of letting quarterly pressure decide it by default. With the CEO and board, I agree a portfolio split, for example 70 percent core, 20 percent adjacent and 10 percent exploratory, and I revisit it a couple of times a year.

The long bets get a protected, bounded budget so they are not raided every time revenue is tight. Crucially, they also get different success criteria. A long bet should be judged on learning milestones, such as "prove the model reaches the accuracy threshold on our data by month four", not on near-term revenue it was never meant to produce.

When pressure rises, I show the cost of raiding the long bets in concrete terms rather than defending them in the abstract. If the board consciously chooses to cut, that is a legitimate decision. What I avoid is the slow, unspoken erosion where long-term work simply starves.

Answers that lose you the room

  • Letting quarterly pressure eat all capacity
  • No separate success criteria

Expect this follow-up: Who agrees the split, and how often?

Scenario 8 Risk & Governance Advanced

Who owns responsible-AI risk in your product organisation?

What the interviewer is testing: Whether responsible AI has clear ownership.

Model answer, red flags and follow-up

A strong answer

I believe product owns responsible-AI risk, because product decides what gets built and who it affects. Legal, security and data teams are essential partners, but if ownership sits entirely with legal, risk gets reviewed late and treated as a blocker.

In practice, I set up a lightweight review that only triggers for high-risk use cases, such as decisions about people, health or money, so the process does not slow everything down. I define launch criteria in advance: minimum performance across user groups, required human oversight, logging and a documented fallback.

Incident response gets defined before scale, not after. That means a named incident lead, a way to disable or restrict the feature quickly, and a communication plan.

I measure whether it works by checking that risks are raised during design rather than in the launch review, and that teams see the process as helpful rather than as a gate to get around.

Answers that lose you the room

  • Leaving it entirely to legal
  • No incident plan

Expect this follow-up: What is your launch bar for high-risk use cases?

Scenario 9 Strategy Advanced

How do you decide which AI capabilities to build in-house and which to partner for?

What the interviewer is testing: Whether you decide build versus partner on strategy.

Model answer, red flags and follow-up

A strong answer

I map each capability on two axes: how strategically differentiating it is, and how fast we need it. If a capability is core to why customers choose us and it is powered by data only we hold, I want to own it, because that is where defensibility comes from. If it is a commodity, such as generic transcription or basic summarisation, I buy or partner so the team's time goes to what is distinctive.

I also weigh speed. Sometimes we buy first to learn quickly, with a plan to bring it in-house once the use case is proven and the data is ours.

I revisit the split about once a year, because the line moves. Something that needed custom work two years ago may now be a cheap API, and something we bought may have become central to our advantage.

I avoid building everything out of pride, and I avoid renting everything and ending up with no moat.

Answers that lose you the room

  • Building everything
  • Never revisiting the split

Expect this follow-up: What would make you buy something you built?

Scenario 10 Culture Practitioner

How do you build a culture of evidence-based decisions across product teams?

What the interviewer is testing: Whether you model and reward evidence over opinion.

Model answer, red flags and follow-up

A strong answer

I start by modelling the behaviour. When a leader brings me a proposal, I ask "what evidence do we have, and what would change your mind?" rather than debating opinions. If I do that consistently, the organisation notices.

Then I give people a shared structure. Every bet is framed the same way: the problem, the hypothesis, the success metric, the cheapest test and a decision date. That makes it easy to compare ideas on evidence rather than on who argues best.

I review outcomes openly, including failures, in a forum where the tone is curiosity rather than blame. And I visibly recognise teams that stop a weak idea early, because that saves the company far more than a late failure.

If a leader keeps ignoring evidence, I escalate the pattern privately with specific examples. Culture is set by what leaders reward, so confident opinions must never beat good data.

Answers that lose you the room

  • Rewarding confident opinions
  • Hiding failed bets

Expect this follow-up: How do you respond to a leader who ignores evidence?

Scenario 11 Executive Alignment Advanced

How do you keep the CEO, CTO and CFO aligned on product direction?

What the interviewer is testing: Whether you align CEO, CTO and CFO with one narrative.

Model answer, red flags and follow-up

A strong answer

I keep one narrative and a small set of company outcomes that all three executives have helped shape. That prevents the common failure where each leader hears a slightly different story and builds different expectations.

I hold a regular cross-functional review, usually monthly, where trade-offs are discussed in shared terms: revenue, cost and risk. The CFO cares about margin and payback, the CTO about feasibility and technical debt, and the CEO about direction. When I translate every choice into those terms, disagreements become about assumptions rather than personalities.

Where I see conflict forming, I raise it early, in a one-to-one first, with two or three options and my recommendation. Nobody should learn about a disagreement in a board meeting.

I also check alignment explicitly by asking each leader to restate the plan in their own words. Differences in those restatements show me where I have misaligned expectations.

Answers that lose you the room

  • Giving each a different story
  • Letting disagreements surface late

Expect this follow-up: What do you do when the CFO and CTO conflict?

Scenario 12 First 90 Days Practitioner

You're a new CPO. What do you do in your first 90 days?

What the interviewer is testing: Whether you listen before you reform.

Model answer, red flags and follow-up

A strong answer

I spend the first weeks listening. I talk to customers directly, to the product leaders and their teams, to sales, support and engineering, and I read the data and financials. I want to understand what is working, what people are afraid to say, and where the real constraints are.

Around week four to six I diagnose three things: strategy clarity, the operating model, and talent. I share an honest assessment with the CEO and leadership team, framed as observations rather than verdicts.

From that I choose two or three high-leverage changes, not a long programme. At least one should deliver a visible early win, such as fixing a decision bottleneck or killing a low-value project, because early credibility pays for bigger reforms later.

I would avoid announcing a reorganisation in week one. It signals that I did not listen, and it scares the people whose knowledge I most need.

Answers that lose you the room

  • Announcing a reorg in week one
  • Ignoring customers

Expect this follow-up: What would be your first visible win?

Scenario 13 Go-to-Market Practitioner

How do you align product with marketing and sales at scale?

What the interviewer is testing: Whether product, marketing and sales share outcomes.

Model answer, red flags and follow-up

A strong answer

The root problem is usually that the three functions have different goals and different timelines. So I start with shared outcomes: product, marketing and sales are all tied to the same customer result, such as activation or revenue from a target segment, not separate departmental targets.

I then build the machinery. A joint launch process with clear stages and owners, a single source of truth for positioning that everyone uses, and regular feedback loops from the field into the roadmap, such as a monthly win-loss review and structured customer input from sales calls.

Decision rights matter as much as process. I make it clear who decides positioning, who decides pricing and who decides launch timing, so disputes do not drag on.

If a positioning dispute arises, I settle it with customer evidence, such as message testing or win-loss data, rather than seniority. Handing a finished product to marketing at the last minute is the pattern I try to eliminate.

Answers that lose you the room

  • Handing off launches
  • Unclear decision rights

Expect this follow-up: How do you resolve a positioning dispute?

Scenario 14 Monetisation Advanced

How would you approach monetising AI features in an established product?

What the interviewer is testing: Whether AI monetisation is tied to value and margin.

Model answer, red flags and follow-up

A strong answer

First I ask whether AI is creating new value or defending existing value. If customers would pay more for what it enables, there is a monetisation case. If it is simply expected, because competitors have it, it may be table stakes that protects retention rather than creating revenue.

Then I choose the model: bundle it into an existing plan, sell it as an add-on, or price by usage. The deciding factor is usually cost behaviour. If cost to serve varies a lot with usage, I prefer tiers or fair-use limits so heavy users do not destroy margin.

I model gross margin at realistic and at ten-times usage, run willingness-to-pay research with real customers, and test pricing before committing. I also design guardrails against bill shock, such as budgets and alerts, because unpredictable charges damage trust quickly.

I avoid adding a price just because the feature is new. Customers need to see the value first.

Answers that lose you the room

  • Adding a price with no value case
  • Bill shock for customers

Expect this follow-up: How do you test willingness to pay?

Scenario 15 Partnerships Practitioner

When should a product organisation pursue a partnership or acquisition instead of building?

What the interviewer is testing: Whether you weigh build versus buy versus acquire.

Model answer, red flags and follow-up

A strong answer

I lean toward partnership or acquisition when speed, capability or distribution matter more than control. If a team elsewhere has already solved a hard problem and the market window is short, building from scratch may mean arriving too late.

The target has to fit our strategy and integrate cleanly. I assess three things before going further: the technology, including how it connects to our stack and data; the talent, since in many deals the people are the real asset; and the culture, because a mismatch can drive the best people out within a year.

I plan integration before signing, not after. That means deciding who leads, what happens to the product and roadmap, how customers are told and how key people are retained.

Acquisitions most often fail because the buyer bought for hype or fear of missing out and had no integration plan. I try to test the strategic logic with a simple question: would we still want this if nobody else was talking about it?

Answers that lose you the room

  • Buying for hype
  • No integration plan

Expect this follow-up: What makes an acquisition fail?

Scenario 16 Reorg Advanced

You must restructure the product organisation. How do you do it well?

What the interviewer is testing: Whether you restructure with strategy and care.

Model answer, red flags and follow-up

A strong answer

I begin with strategy, not boxes. What does the company need to win, and what structure would help the teams deliver that? Only then do I design the organisation, usually around customer journeys or outcomes rather than technical components.

I involve my leaders early, because they know where the real dependencies and risks are, and because people support what they help shape. Before any announcement, I make sure I can explain the reasons, the timeline and what changes for each person.

Communication is where reorganisations succeed or fail. I explain the reasoning plainly, support people whose roles change, and give clear answers on what happens next. Silence creates rumour and attrition.

I commit to a review after about six months, looking at decision speed, delivery of outcomes, team health and attrition. If the structure is not producing better results, I adjust it, because a reorganisation is a hypothesis too.

Answers that lose you the room

  • Reorganising without a reason
  • Poor communication

Expect this follow-up: How do you know the reorg worked?

Scenario 17 Portfolio Advanced

How do you rationalise a sprawling product portfolio?

What the interviewer is testing: Whether you can retire products responsibly.

Model answer, red flags and follow-up

A strong answer

I evaluate each product on the same dimensions: customer value, strategic fit, revenue, cost to run and overall health, including technical debt and team capacity. Putting everything in one view usually exposes the long tail of products that consume attention without contributing much.

Each product then goes into one of four buckets: invest, maintain, merge or retire. The harder cases are products that are loved by a small group but strategically peripheral. For those I look at whether the customers can be served elsewhere.

Retiring a product is a customer problem as much as a business one. I plan migration paths, timelines and support before announcing anything, protect key accounts and communicate early and specifically.

I also redeploy the freed-up people and budget visibly, so the organisation sees that pruning creates room for better work. Keeping every product alive is its own strategic choice, and usually a poor one.

Answers that lose you the room

  • Keeping every product alive
  • Ignoring migration

Expect this follow-up: How do you tell a customer their product ends?

Scenario 18 Customer Insight Practitioner

How do you keep the organisation close to customers as it grows?

What the interviewer is testing: Whether customer proximity is institutionalised.

Model answer, red flags and follow-up

A strong answer

I make customer contact part of how the organisation works, not a research team's job. Every PM does regular customer interviews, I would expect at least a few a month, and findings go into a shared repository that anyone can search so insight does not stay trapped in individual notebooks.

Leaders must join those conversations too. I ask my directors to sit in on customer calls and to bring one customer insight to each leadership review. If leaders are detached, the whole organisation reads that as a signal.

I also add a customer-outcome review to every planning cycle, where teams show how their work changed something for real customers, not just what shipped.

As the company grows, layers form between decision-makers and users. These habits are how I keep that distance from growing, and I check them by asking teams when they last spoke to a customer.

Answers that lose you the room

  • Relying on research teams only
  • Leaders detached from customers

Expect this follow-up: What ritual keeps leaders close?

Scenario 19 North Star Practitioner

How do you choose a north star metric and avoid gaming it?

What the interviewer is testing: Whether the north star is guarded against gaming.

Model answer, red flags and follow-up

A strong answer

The north star should reflect value actually delivered to the customer and also correlate with revenue over time. For a collaboration tool, "weekly active teams completing a shared task" is better than "registered users", because it shows real use.

Any single metric can be gamed, so I pair it with guardrails. If the north star is engagement, the guardrails might be quality, support contacts and cost to serve. If it is task completion for an AI feature, a guardrail would be harmful-output rate and cost per task.

I review it regularly and test whether team-level input metrics really drive it. If a team hits its input metric and the north star does not move, the metric tree is wrong and needs fixing.

A bad north star is a vanity metric like total sign-ups or page views. It rises while the business learns nothing, and teams optimise for movement instead of value.

Answers that lose you the room

  • A vanity metric
  • No guardrail metrics

Expect this follow-up: Show me a bad north star and why.

Scenario 20 Leadership Advanced

One of your senior product leaders is delivering but hurting team morale. What do you do?

What the interviewer is testing: Whether you act on behaviour despite results.

Model answer, red flags and follow-up

A strong answer

I would start with evidence rather than reputation. I gather specific examples of the behaviour and its effect: who left a meeting demoralised, which decisions were made without input, what people have said in one-to-ones and in engagement data.

Then I have a direct conversation. I describe what I observed and the impact, without labels, and I ask for their view, because there may be context I am missing. I set clear expectations for what must change, offer support such as coaching, and agree a timeline for checking progress.

Results do not outweigh behaviour, because a leader who damages morale eventually costs the company its best people and the results that depended on them. If the behaviour does not improve after fair feedback and support, I am prepared to move them out of the role.

What I avoid is excusing it because the numbers are good, or acting on rumour without evidence.

Answers that lose you the room

  • Excusing a high performer
  • Acting without evidence

Expect this follow-up: What would make you remove them?

Scenario 21 AI in Product Org Practitioner

How do you build AI capability across the whole product organisation?

What the interviewer is testing: Whether you scale AI capability across the org.

Model answer, red flags and follow-up

A strong answer

Training alone does not build capability, so I combine several mechanisms. A baseline of data and AI literacy for everyone in product, so they share vocabulary. Shared playbooks for the practical parts: how to design evaluations, how to handle data, and how to run a responsible-AI review. Embedded ML partners who sit with product teams on real work. And hands-on pilots where teams learn by shipping something small.

I measure it, otherwise it is just activity. Adoption is one indicator, such as how many teams use the playbooks, but the better ones are outcomes: quality of eval sets in proposals, time to ship AI features, and incidents avoided.

Tools and best practice change quickly, so I assign owners to keep guidance current and review it every quarter.

A single training session is the most common failure. It creates the impression of progress with no change in how work gets done.

Answers that lose you the room

  • One training session
  • No measurement

Expect this follow-up: How do you keep guidance current?

Scenario 22 AI Incident Advanced

Your AI product produces a harmful output that goes viral. What do you do?

What the interviewer is testing: Whether you lead a public AI incident calmly.

Model answer, red flags and follow-up

A strong answer

My first priority is to contain the harm. That means disabling or restricting the feature quickly, even if it hurts short-term metrics, because every hour of exposure compounds the damage. I would activate the incident process with a named lead.

In parallel, I begin investigating root cause: was it a model failure, a prompt or guardrail gap, a data problem or an unanticipated use? And I communicate. I would not wait for a perfect explanation before speaking, because silence reads as indifference. I would acknowledge the issue plainly, say what we know and what we are doing, and update as facts emerge. One designated spokesperson, usually the CEO or a senior communications lead, avoids mixed messages.

I never blame users. Even if misuse was involved, the lesson is that our safeguards were not strong enough.

Afterwards, I run a blameless review, fix the cause and strengthen governance so the same class of failure is caught earlier.

Answers that lose you the room

  • Waiting for a full investigation to speak
  • Blaming users

Expect this follow-up: Who speaks for the company?

Scenario 23 Market Strategy Practitioner

How would you adapt product strategy for the Indian market?

What the interviewer is testing: Whether you adapt strategy to local reality.

Model answer, red flags and follow-up

A strong answer

I would start by questioning the assumptions imported from other markets. In India the important variables are usually price sensitivity, with many customers unwilling to pay global price points; mobile-first usage, often on mid-range phones and variable connectivity; language diversity, where English-only products miss large segments; and payment habits, including the dominance of UPI and a preference for small or flexible payments.

From there I adapt the product: pricing and packaging, onboarding that works on low bandwidth, support in local languages and channels, and features designed around how people actually pay and share. Local partnerships can help with distribution and trust where we lack presence.

Most importantly, I validate with local customers rather than relying on global research. I would test the riskiest assumption first, probably willingness to pay and the right price point, with a small experiment before building anything large.

The failure mode is copying a global playbook and expecting it to land unchanged.

Answers that lose you the room

  • Copying global playbooks
  • Ignoring price sensitivity

Expect this follow-up: Which assumption would you test first?

Scenario 24 Innovation Practitioner

How do you protect space for innovation without hurting core delivery?

What the interviewer is testing: Whether you protect innovation without hurting the core.

Model answer, red flags and follow-up

A strong answer

I ring-fence a small team and a bounded budget for exploratory work, with its own success criteria. If exploratory bets are judged by the same quarterly metrics as core delivery, they will always lose, so I measure them on learning: what did we prove or disprove, and how cheaply.

I use stage gates so the work does not drift forever. Each stage has a clear question, a timebox and a decision at the end: continue, pivot or stop. That keeps the budget honest and prevents zombie projects.

When an idea works, it must transition into a core team with proper support, including ownership, a roadmap slot and engineering capacity. Many promising ideas die at that handoff because nobody was ready to adopt them, so I plan the transition from the start.

To protect core delivery, I keep the exploratory group small and separate its budget so that it does not quietly borrow from the core team.

Answers that lose you the room

  • Starving exploratory work
  • No stage gates

Expect this follow-up: How does an idea move into core teams?

Scenario 25 Pet Projects Practitioner

The CEO pushes a pet project that doesn't fit strategy. How do you handle it?

What the interviewer is testing: Whether you handle CEO ideas by testing, not refusing.

Model answer, red flags and follow-up

A strong answer

I begin by understanding the intent behind the idea. Is the CEO responding to a customer, a competitor, a board conversation or a personal conviction? The underlying goal is often legitimate even when the proposed solution does not fit the strategy.

Then I propose testing it cheaply. We define what success would look like, run a small prototype or fake-door test, and agree in advance what result would justify more investment. I also show the trade-offs honestly: what we would stop or delay to fund it.

If the test shows promise, we scale it with proper resourcing. If not, the data lets us stop it constructively, without turning it into a loss of face for the CEO. I would present the outcome as "here is what we learned" and not "I told you so".

A blunt no damages the relationship and often drives the idea underground. Building it with no criteria wastes capacity and sets a precedent that pet projects bypass strategy.

Answers that lose you the room

  • Saying no bluntly
  • Building it without criteria

Expect this follow-up: How do you stop it without embarrassment?
