Git Interview Prep

Use this page as a revision map. Every tutorial in the Git track already ends with interview questions — work those first, then stress-test the themes below.

How to practise

  1. Answer out loud in two minutes without notes
  2. Draw the architecture on paper or a whiteboard
  3. Name the failure mode and the first three debug commands
  4. Tie the topic to security (identity, secrets, blast radius)

High-yield themes

  • Object model (blob/tree/commit)
  • Merge vs rebase
  • Force-with-lease vs force
  • Bisect strategy
  • Monorepo workflows
  • Signed commits and provenance

Hands-on prompts interviewers love

  • Walk through a recent lab from the track as if it were an incident
  • Compare two designs and defend a trade-off (simplicity vs resilience)
  • Explain what you would monitor after a change ships
