The Danger Zone: Top Reasons Candidates Fail

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

Being defensive or blaming the person giving feedback.
Focused only on a single negative customer review without broader context.
Describing the 'win' as a pre-defined, obvious success metric.
Using a single linked list which makes removal O(N).
