The Danger Zone: Top Reasons Candidates Fail

Based on our database of Plum interview outcomes, avoid these common traps:

  • Not considering external factors (e.g., holidays, competitor activity, market news).
  • Failing to demonstrate clear value proposition early in the flow.
  • Listing only direct competitors without considering indirect or substitute solutions.
  • Focusing solely on the primary metric (goal completion) without considering secondary or business impact metrics.
