The Danger Zone: Top Reasons Candidates Fail

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

  • Making superficial changes without addressing underlying design issues.
  • Giving a generic answer not tailored to Zalando or the retail industry.
  • Inefficient data structures leading to O(n*m) complexity where n is orders and m is products.
  • Ignoring latency requirements for transaction processing.
