The Danger Zone: Top Reasons Candidates Fail

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

  • Focusing solely on personal career advancement without mentioning company mission or product.
  • Choosing inappropriate storage solutions (e.g., relational DB for raw pings).
  • Inefficient data structures for stream processing (e.g., repeatedly scanning entire history).
  • Ignoring the distinction between peak and off-peak hours.
