The short version

Why the Genai Engineer interview is hard

Generative AI interviews test judgement about when to use which tool. Prompting, retrieval and fine-tuning solve different problems, and a large part of the assessment is whether you know which one a given failure actually calls for.

What to expect

The rounds you should rehearse

01

RAG design

chunking, retrieval quality and why the wrong context produces the wrong answer.

02

Fine-tuning versus retrieval versus prompting

choosing based on the failure you are seeing.

03

Hallucination

reducing it, detecting it, and designing for the times it happens anyway.

Avoid these

The mistakes that quietly sink candidates

  • Proposing fine-tuning for a problem that is plainly a retrieval failure.

  • Treating chunking as a detail when it frequently determines whether RAG works at all.

  • Having no evaluation approach, so no way to tell whether a change helped.

Reading the questions is not practicing them.

Run a live voice mock tuned to the Genai Engineer interview. It follows your answers, probes the gaps, and scores you like a senior interviewer would.

FAQ

Questions, answered.

When should I fine-tune instead of using RAG?
Broadly, retrieval addresses missing knowledge while fine-tuning addresses behaviour, format or style the model will not adopt from prompting. Reaching for fine-tuning to inject facts is the most common misdiagnosis in these interviews.
How do I talk about hallucination well?
Treat it as a system property rather than a model defect. Discuss grounding answers in retrieved context, citing sources, and designing a path for the cases where the model is wrong anyway.
