I've interviewed with two schools so far, most of the questions are pretty general and generic but here are some that I remember:
What is OT and where do you find OT?
Why OT?
Why this specific program?
How do you handle stress?
Tell me about a negative experience you had and how you dealt with it
How would you work with a patient that doesn't agree with your healthcare beliefs (something along these lines)
What makes you a unique candidate for this program.
