The Danger Zone: Top Reasons Candidates Fail

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

Describing a generic 'check-in' rather than a strategic intervention.
Describing a situation where they simply gave in without discussion.
Waiting until the customer explicitly states intent to leave.
Not taking responsibility for their part in the conflict.
