I was actually asked several ethics questions, including the "owner comes in with hbc puppy and his 10 y.o. son...you can't do pro bono work and you need to make a decision now", "what would you do if you saw several classmates cheating?", and "if you knew a prof wasn't giving the most up to date information, what would you do...would you talk with other students first or go to the prof first?" I think that some of the ethics questions were geared toward the fact that I have a much more researchy background and less clinical experience (but want to go into the clinical side of things) and that I have a non-life sciences educational background.
