The Danger Zone: Top Reasons Candidates Fail

Based on our database of N=5 interview outcomes, avoid these common traps:

Failing to break down the APAC region into meaningful sub-segments (e.g., by country or economic development).
Describing a situation where they simply presented their idea without addressing the other person's concerns.
Focusing solely on their own contributions rather than team leadership.
Failing to articulate concrete steps taken to address the issue or prevent recurrence.
