Some that I remember from EMT interviews:
Why do you want to work here? Why EMT
Conflict with a coworker
Example of how you manage your time
Describe a time you were under a lot of stress
A time you demonstrated leadership
The only one that I really blanked out on was about describing a time a customer complained about something and how I solved it. I only had one service job, in high school, and I hadn't been in that situation.
