The Danger Zone: Top Reasons Candidates Fail

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

  • Blaming the other party or focusing solely on their shortcomings.
  • Using a simple list or array and performing linear scans for all operations, leading to poor performance.
  • Focusing on syntax errors instead of logical flaws.
  • Not considering how to handle recurring medications or complex schedules.
