fundamentals

The question behind every AI product decision: a repeatable test, applied step by step, and the willingness to say 'a rule does this better' when it does, and 'a model, with a reviewer' when it does not.

Often the first question in an AI PM loop. Generic answers ('AI is uncertain') score poorly; concrete changes to specs, testing, cost and launches score well.

Explain the task a product handles well, compare the current alternative and defend one improvement with evidence from actual use.

A shared vocabulary for one of the biggest decisions in AI product design: how much the AI does on its own. The interviewer wants the levels, and the rule for choosing among them.

A deceptively simple design question. Numbers feel transparent, but most users cannot act on them, and the numbers are often less meaningful than they look.

Streaming is the cheapest latency improvement in AI products. The interviewer wants the reason, the trade-offs, and the cases where showing partial output is a mistake.

A common dismissal with a two-sided answer. The interviewer wants you to separate what is weak about thin wrappers from what makes many successful software businesses 'wrappers' too.

A strategy vocabulary question with a skeptical edge. The interviewer wants to hear the difference between data that improves the product and data that just accumulates.

A big-picture question that tests whether you can reason about industry structure rather than repeat headlines. A good answer explains each layer's economics and where defensibility lives.

The first vocabulary word of AI product management. Tokens are the unit of cost, speed and memory, and a PM who can't reason in them can't price, budget or design an AI feature.

A fundamentals question that comes up when a stakeholder notices the assistant answered differently yesterday. The good answer explains sampling in one minute and then turns it into product decisions.

A vocabulary check on one of the most important model developments of recent years. The good answer explains the trade (accuracy for time and money) and gives a rule for when it pays.

A fluency question about the request path. The interviewer does not need the maths; they want to know you can connect each stage to latency, cost and design decisions.

A small architectural component with outsized strategic value. The interviewer wants to hear what it does day to day and why it matters when a provider changes prices or goes down.

A short question with a large payoff. A PM who knows the one rule of prompt caching can cut a feature's input bill dramatically without touching quality.

Without traces, every quality complaint is a guess. The interviewer wants the fields that make debugging, evaluation and cost control possible, and an awareness of what should not be stored.

A definitions question that comes up early in agent rounds. A precise answer here sets up every design answer that follows.

A fundamentals question with a trap: the model never touches your systems. Getting that right is what lets a PM reason about safety and control later.

Explain what a passing test suite establishes, what a behavior evaluation adds and why one critical failure can still block an otherwise strong result.

A fundamentals question. The AI twist is that the fastest leading indicators come from what users do with the output in the first few seconds.

The top entry on the OWASP list for LLM applications. A PM should be able to explain it in a minute, distinguish the direct and indirect forms, and explain why it changes how products are designed.

A common event with a calm answer. The leak itself is usually not the problem; what the prompt contained and what it was being trusted to do might be.

A role-understanding question common in lab interviews. A crisp answer shows you know who the customers are, what decisions you own, and how success is measured.

A vocabulary question that unlocks cost, latency and on-device decisions. The interviewer wants the idea, the trade-off and when it matters to a product.

A new term for a new skill. The interviewer wants a definition, a sensible use for PMs, and an honest view of where AI-built prototypes stop being trustworthy.

A practical question about the PM toolkit. The interviewer wants tool categories matched to the question you're trying to answer, not brand loyalty.

An instruction file is a short brief every coding agent reads before it starts. The answer that scores keeps it short, puts the commands and the never-do rules first, and explains each line.

STAR is the format employers name; adding a learning step and choosing stories with AI-specific judgment is what lifts it. How to structure, time and bank your stories.
