The Danger Zone: Top Reasons Candidates Fail

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

  • Not explaining the 'why' behind their proposed strategy.
  • Choosing an inappropriate sample size or test duration, leading to unreliable results.
  • Proposing a solution that doesn't leverage Moss's existing strengths (e.g., card issuance, expense management).
  • Underestimating the complexity of international expansion.
