The Danger Zone: Top Reasons Candidates Fail

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

  • Focusing on the disagreement rather than the strategy used to gain buy-in.
  • Getting lost in mathematical details without explaining the core concept or practical application.
  • Focusing only on shortest distance without considering traffic, delivery time windows, vehicle capacity, or driver constraints.
  • Failing to identify appropriate decision variables, objective functions, and constraints for a logistics problem.
