An AI interviewer that asks one hard question at a time, listens to your answer, and tells you plainly where it fell short — across the five rounds data and cloud engineers actually get asked.
8 exchanges a day, free, no sign-up. Pro lifts it to 200.
How it works
Reading interview questions tells you whether you recognise an answer. It doesn't tell you whether you can produce one under pressure, in order, out loud. This closes that gap.
01
Pick a track
Choose the round you're actually about to sit. Each track has its own interviewer persona and question progression.
02
Answer out loud, in writing
The coach asks one question at a time, exactly like a real interviewer. No multiple choice, no hints up front.
03
Get told what was weak
After every answer: what landed, what didn't, and what a strong answer would have covered. Then the difficulty steps up.
Tracks
Each track runs its own persona and its own difficulty curve.
🧱Data Engineering
Pipelines, orchestration, modelling, and the reliability questions that separate senior from mid.
🗄️SQL
Joins, window functions, and the query-optimisation follow-ups interviewers use to go deeper.
☁️AWS / Cloud
Architecture trade-offs across compute, storage, and networking — including the cost questions.
🐍Python
Data structures, production patterns, and the code-quality probing that follows your first answer.
💬Behavioural
STAR-method situational rounds, with feedback on structure rather than just content.
What this isn't. It won't hand you a job, and it can't tell you what a specific company will ask. It's a rehearsal room: somewhere to be bad at answering before it costs you an offer. If you're a week out from an on-site, that's worth a lot. If you're browsing, the free tier is genuinely enough.
