The Danger Zone: Top Reasons Candidates Fail

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

  • Using a simple sort on a list for each median calculation, leading to poor performance.
  • Incorrectly handling timestamp comparisons or window boundaries.
  • Inadequate error code definitions or messages.
  • Calculating percentage change incorrectly (e.g., using absolute difference instead of relative).
