AI · ML · GENAI ENGINEER INTERVIEWS / 957 QUESTIONS

Ace every round of the AI interview.

Know what each round is testing, before you are in it.

The AI engineer interview is a loop of rounds, and each one screens for something specific. This site maps 957 real questions, 230 concepts and 40 company loops onto that sequence, so you prepare for the round you are actually about to sit, not a generic one.

THE LOOP

Five rounds. Every one of them has a question bank, and every sample here is free to read.

Loops differ by company, but the rounds recur. Each one below shows the topics it draws on, with live counts, and two questions the way they are actually asked.

  1. R1

    Recruiter and hiring-manager screen

    Whether your story matches the role, and whether you know which loop you are walking into.

    Behavioral & Project Deep-Dives62What the role actually isThe loop at your target company

    62 questions in this round

  2. R2

    Coding

    Practical builds and the LeetCode-medium staples, with the data plumbing underneath.

    Coding & DSA144SQL & Data Engineering58

    202 questions in this round

  3. R3

    ML and LLM fundamentals

    The conceptual core: attention, sampling, evals, metrics, calibration, the modeling basics still tested beside GenAI.

    261 questions in this round

  4. R4

    System and ML design

    The modal round: RAG and agents, production trade-offs, GPUs, MLOps, security, and the model behind a product.

    432 questions in this round

  5. R5

    Behavioural and project deep-dive

    The highest-variance rounds and the least prepared for: the system you shipped, the model that failed, the trade-off you owned.

  6. ↻

    Then the loop at the company that is actually interviewing you.

    40 company guides. 25 loops documented round by round with what each stage screens for; 10 partly verified and marked as such. Where we are not sure, the page says so.

WHAT AN ANSWER LOOKS LIKE

Not a list of questions. Answers with the parts an interviewer is listening for.

A question you can look up anywhere. What a room rewards is the shape of the answer: what to say first, where the depth is, the follow-up they hold in reserve, and the mistake that sounds right. Every one of the 957answers here carries all four. This is today's, unedited, from the free window.

Grounded in real GenAI, LLM, and AI/ML engineering interview loops and written to a senior-engineer editorial bar.

What does a CI/CD pipeline for ML add over a standard software CI/CD pipeline?

TL;DRwhat you say if they cut you off
ML CI/CD retains everything standard CI/CD does (lint, tests, build, deploy) and layers on three items, because the model is a function of data, not code alone: validate incoming data (schema, distribution), gate on model quality (a retrained model has to beat the incumbent on a held-out, time-correct eval, not just clear unit tests), and version data + features + model + code together so any run reproduces. Deployme…
HOW TO APPROACH ITthe order, and the clarifying questions
Note the shared base in one sentence, then spend your time on what is ML-specific. The framing that scores: in software, behavior comes from code; in ML it comes from code and data, so the pipeline must test, gate, and version the data path as well. The rest follows from that.
THE FOLLOW-UPwhat they probe next, with the strong reply
"Why isn't passing unit tests enough?" Unit tests check code correctness; they cannot tell you the model got worse. You need an eval-vs-baseline gate.
THE MISTAKEwhat sounds right and loses the offer
Describing plain software CI/CD and missing data validation and the model-quality gate. Promoting a model because the pipeline "passed" without comparing it to the incumbent. Versioning only code, so a production model cannot be reproduced or audited. Straight-to-prod deploys with no canary, trustin…

AFTER TWENTY QUESTIONS

It starts telling you where you are weak.

Reading answers is passive, and a chat window forgets you when you close it. One tap after each answer, Got it, Shaky or Review, feeds a per-topic recall estimate built on knowledge tracing, the model behind intelligent tutoring systems. Your next focus is your weakest round, not a random question.
