Can you walk me through a time you optimised a slow database query? I'd love to hear the impact.

Sure — we had a report page timing out. I profiled the query and found a missing composite index…

Good start. How did you decide which columns to include in the composite index, and did you consider query plan changes?

Everything you need

Three steps to your offer.

Practice the interviews, perfect the CV that gets you in the room, and target the exact job you want — one platform for the whole journey.

01

Practice real interviews

A voice AI interviewer that pushes back, follows up, and lets you think through general, tech knowledge, mixed, coding, system design, data analytics, and case study.

Voice interviews with personas

Choose Friendly, Professional, or Stress-test mode. The AI adapts its follow-ups to your answers in real time.

Coding interviews + runnable tests

Write code in a live editor, the AI runs your test cases and probes your reasoning as you go.

General interview practice

Practice clear, specific stories about ownership, trade-offs, teamwork, and impact.

Tech knowledge interviews

Talk through role-specific concepts, design choices, debugging, and trade-offs without live coding.

System design on a whiteboard

Sketch the architecture on a live canvas while you talk it through, then defend it under scale and failure.

Data analytics case studies

Work a business case from a data table: pick the metrics, reason through the numbers and make a recommendation.

Replay + per-question feedback

Every answer is scored with model answers, so you know exactly what 'great' looks like for each question.

02

Perfect your CV
