🗣 Behavioral Interview Example
Q: Tell me about a time you failed
STAR Framework Answer:
Situation: I was responsible for developing a core functional module in an urgent project.
Task: Needed to complete development and testing within two weeks.
Action:
- Underestimated the technical difficulty and did not seek help in time.
- Only discovered architectural design issues in the last week.
- Although I worked overtime, it was eventually delayed by 3 days.
Result:
- The project delay affected the overall schedule.
- Learned to identify risks early.
- Established a daily synchronization mechanism afterward.
- Applied these lessons in subsequent projects and never had delays again.
