Practice these

05

Where people slip

  • !Generic motivation that could apply to any AI company
  • !Buzzword-heavy answers without mechanisms
  • !No measurable impact or personal ownership
  • !Ignoring cost, latency, safety or operational constraints
  • !Treating reported questions as a script rather than preparing underlying skills

06

Ask them this

  • ?What distinguishes strong performance in the first six months?
  • ?Which model, data or product constraint most limits the team today?
  • ?How are research, product and engineering decisions resolved?
  • ?How does the team evaluate AI quality before and after launch?
  • ?What is the policy on AI-tool use during each interview stage?
