The Danger Zone: Top Reasons Candidates Fail

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

  • Blaming the other party entirely without acknowledging their perspective.
  • Not demonstrating an ability to find common ground or compromise.
  • Not considering the streaming nature of the data and proposing an offline batch solution.
  • Lack of consideration for fault tolerance and message guarantees.
