Candidate
Design a RAG pipeline for an enterprise knowledge base with 10 million documents.
I'd use hybrid retrieval — dense embeddings plus BM25, with a cross-encoder re-ranking layer...
You mentioned latency — how do you handle the cross-encoder overhead at query time when SLA is under 200ms?

How it works

A real interview, not a quiz

Multi-level follow-ups. Structured phases. Up to 60 minutes. Exactly like the real thing.

01
Set your duration and role
Choose 30, 45, or 60 minutes. Pick your role. Paste the JD. The AI structures the session into Intro, Technical, System Design, Behavioural, and Closing phases.
02
Speak — AI digs 3 levels deep
Every answer triggers 2-3 RAG follow-ups before moving to the next topic. The AI references your exact words and probes gaps — just like a real senior engineer would.
03
Get per-phase feedback
Every answer is scored. Feedback is organised by interview phase — technical depth, behavioural structure, communication — with specific, actionable coaching.

Engineers who landed the job

★★★★★
"The 3-level follow-ups are what make this different. Sarah picked up on something I said about latency trade-offs and drilled into exactly what Google asked me the next day."

LLM Engineer → Google
★★★★★
"I did the 60-minute session the night before my Amazon loop. The structure was identical — intro, technical, system design, behavioural. Passed first try."
SC
Sofia C.
AI PM → Amazon
★★★★★
"James is brutal in the best way. He pushed back on every vague answer across the full 45 minutes. After 4 sessions I felt genuinely ready for anything."
