The Danger Zone: Top Reasons Candidates Fail

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

  • Describing a situation where they were simply doing their job.
  • Not explaining the impact or learning from the experience.
  • Suggesting vertical scaling as the primary solution without considering horizontal scaling.
  • Not considering the impact of the fix on other parts of the system.
