General and behavioral questions

7. Tell me about yourself.

Give a 60–90 second summary: your background, the training or experience that prepared you for this role, and why this employer. Keep it relevant to postal clerk work.

8. Describe a time you made a mistake. What did you do?

Pick a real, low-stakes example. Explain how you owned it, fixed it and changed your process. Employers want honesty and learning, not perfection.

9. How do you handle stress or a heavy workload?
