The Danger Zone: Top Reasons Candidates Fail

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

  • Choosing a data structure that doesn't support efficient updates and top-K retrieval.
  • Generating levels that are too linear or repetitive.
  • Using a brute-force approach instead of a graph traversal algorithm.
  • Using a polling mechanism instead of push notifications.
