here's plenty of them

I just had an interview of this sort 2 weeks ago (i found out yesterday i got the job).
remember for every question they want to hear 3 parts:
1. a real situation
2. your actual actions
3. why everything was okay in the end and what you learned (if you learned nothing, pretend you weren't sure of something and say you learned/confirmed that)
remember, be calm and positive.. even if you're telling a story about your balls getting kicked in and your hair getting ripped out.. make it an uplifting it-wasn't-all-THAT-bad kind of story.
good luck!
