25 Real Tech Interview Questions (Free PDF) with Roni Das

A free PDF of 25 real interview questions for engineering jobs in AI and machine learning, answered in full. It has 5 sample questions from each of my 5 interview prep packs: AI Engineering, GenAI and LLM Engineering, Inference Engineering, Maths for ML, and Forward Deployed Engineer.

Every question comes with what the interviewer is testing, at least one diagram, a model answer, key points, likely follow-up questions with hints, and common mistakes. A level badge (Junior, Mid, Senior or Staff) shows how deep the answer needs to go.

The full packs, with 100 to 150 questions each, are listed on this profile. If these 25 help you, that is where the rest are.

Format: one PDF of 79 pages, delivered here right away. Written by Roni Das, Senior Enterprise Architect, in simple English.
