System design mock interview

Practice a live, spoken system design interview — architecture decisions, trade-offs, and scaling, with an interviewer that pushes on the specifics of your design instead of accepting a surface-level answer.

What to expect

  • A real-world design prompt, tailored to your experience and target role
  • Follow-up questions on trade-offs, bottlenecks, and failure modes as you talk through your design
  • A scorecard covering system-design depth alongside communication and clarity
