The Danger Zone: Top Reasons Candidates Fail
Based on our database of Corgi interview outcomes, avoid these common traps:
- Not accounting for race conditions when updating referral counts
- Using an O(n^2) approach by comparing every interval
- Using a nested loop resulting in O(n^2) complexity
- Using a data structure that doesn't support O(1) access
