40 AI interview questions asked at product companies

Grouped by round — screening, applied build, system design and stakeholder — with the answer structure interviewers score against.

Key takeaways up front

  • Four rounds, four different scoring rubrics
  • Trade-off reasoning scores higher than correct answers
  • Cost and failure handling are the most-missed topics

These questions come from debriefs with ACRY learners who interviewed at product companies, GCCs and AI-first startups over the last two quarters.

1Round 1 — Screening

Testing whether you have shipped anything real.

  • Walk me through a project you built end to end
  • What broke, and how did you find out?
  • How did you measure whether it worked?
  • Which parts did you not build, and why?

2Round 2 — Applied build

Usually a live or take-home task with an assistant allowed.

  • Given this dataset, design a retrieval strategy
  • Reduce this pipeline's cost by half without losing quality
  • Add an evaluation harness to this prototype

3Round 3 — System design

They want your reasoning about trade-offs: latency versus quality, fine-tuning versus retrieval, human review versus full automation.

4Round 4 — Stakeholder

How you would explain a failure to a business owner, and how you would decide not to build something.

What to do next

  • Prepare one project you can narrate at four levels of depth.
  • Always volunteer cost, latency and failure handling.
  • Practise saying 'I would not build this' with a reason.
