The project deep-dive round

Comes up in: Hiring manager

This concept is being written. It gets the full five steps — explanation, predict, interview angle, practice with tests, and review cards. Here is exactly what it will cover, so you can study it elsewhere in the meantime.

What it covers

  • choosing the project
  • the 5-minute overview (problem, users, constraints, your role, architecture, results)
  • preparing for depth probes (why this choice, alternatives, what broke, what you would change, metrics)
  • drawing the architecture
  • owning mistakes

Words you will know

project deep-dive

What you will practise

  • prepare and record a deep-dive
  • answer the 15 standard probe questions (self-run mock) or have a peer probe it

Interview questions this answers

  • Walk me through the most complex project you have worked on.
  • What would you do differently if you rebuilt it today?
  • How do you mentor engineers?
  • How do you decide what not to build?
