Duolingo AI Strategy, Moats & Pricing interview questions

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 market-entry question where copying the US playbook fails. The interviewer wants segments, languages, pricing that works with inference costs, distribution and the competitive landscape.

The strategy question every AI application company faces. 'Better prompts' is not an answer. The interviewer wants a ladder of defensibility and a plan to climb it.

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.

Platform risk made real. The answer is neither panic nor dismissal: work out which customers are actually at risk, double down on what the provider cannot easily do, and reduce dependence where it matters.

A strategic decision with a clear default and specific reasons to deviate. The interviewer wants a framework grounded in evals, volume, constraints and team capacity.

AI changes pricing because each use costs money and value per use varies. The interviewer wants the trade-offs of each model, matched to the product, and a hybrid that protects margin.

A high-stakes strategic question where the answer is usually no, but not always. The interviewer wants the real goal behind the request, the economics, and a recommendation the CEO can accept.

An incumbent's dilemma. Bolting a chatbot onto the old product rarely works; copying the startup ignores your strengths. The interviewer wants a response that uses the incumbent's assets.

A principal-level strategy question with business, ecosystem and safety dimensions. There is no universal right answer; the interviewer wants a decision framework tied to the lab's business model and the model's risk profile.

A pricing question about where the value of falling model costs should go. The answer depends on margin targets, competition and whether price or capability wins customers.

A positioning question where horizontal products face the model providers head-on and vertical products face smaller markets. The interviewer wants a framework and a choice.

Generous terms now, constraints later. The interviewer wants the value of the offer weighed against the cost of losing optionality, and a counter-proposal that keeps the benefits without the trap.

AI features commoditise fast because everyone can access similar models. The interviewer wants a move from feature advantage to workflow, data and outcome advantages, with a plan for the feature itself.

A packaging decision with adoption, revenue and margin pulling in different directions. The interviewer wants the trade-offs and a structure that captures value without stalling adoption.

The innovator's dilemma in SaaS form. If you don't ship the AI, competitors will; if you do, per-seat revenue shrinks. The interviewer wants a pricing and product transition that grows revenue with the work done.

A principal-level strategy question for a company whose discovery layer could be disrupted by AI assistants. The answer must cover defence, offence, operations and platform risk, with sequencing and measures.
