What a full session looks like
One continuous interview, not isolated questions
Set your role and the bar, then move through round after round on the clock — each answer can trigger a follow-up probe, just like the real loop. Run the full loop, or focus a session on one round.
- 1 Set up Role, experience level, focus area and round length.
- 2 Behavioral STAR-style questions about real impact, on a timer.
- 3 Technical Role-specific depth and tradeoff reasoning.
- 4 System design Open-ended design, probed for clarity.
- 5 Readiness report One scored summary with your next moves.
Multi-round flow
Behavioral, technical and system design — in one sitting
Pick your role and paste the job description, then sit a continuous interview that moves round to round on a real clock — not a pile of isolated cards.
- One continuous session, not separate drills
- Realistic time pressure on every answer
Adaptive probes
Follow-ups tuned to what you said
Each answer can trigger a follow-up generated from your own words — you have to go deeper before you advance, the way a real interviewer pushes.
- Probes built from your actual answer
- Tests depth, not just recall

Dial in the exact interview you're walking into
Set seniority, focus area and the clock so the session matches the real thing — Entry to Staff, behavioral to system design, 2 to 4 minutes an answer.
- Experience level + focus area
- Round length on a timer
