## Description

Practice system design interviews by talking through them.

  Jobby is a voice-first mock interviewer. You speak your design out loud. It listens, asks follow-ups,
  challenges your tradeoffs, and scores you when you're done.

  42 problems. Pick one and go.
  Covers every major pattern — URL shorteners to distributed databases. Each problem has a study guide so
  you can learn before you practice.

  Two modes.
  Practice mode walks you through it together. Interview mode doesn't help — it pushes back, probes
  assumptions, and stays quiet when you're stuck. Just like the real thing.

  Scored on 5 dimensions.
  Structure, clarity, tradeoff reasoning, handling pushback, and conciseness. Every session ends with a
  report card and specific feedback.

  Pause and resume anytime.
  Mid-interview and need to stop? Pick up exactly where you left off.

  2 problems a day. Done in 3 weeks.
  Reading doesn't stick. Talking through designs does. That's the whole idea.
