Yes you can expect a few questions coming from them..... and try to be as open as you can.

But I would also take my own list of questions like......

Do they do therapy and if so what type of therapy?
How long are sessions?
What areas of mental illness if any do you focus on? (Some p'doc's are well versed in say bipolar for instance and not so much on eating disorders).
If you think you have a specific area ask them how they deal with that.

Its true some psychiatrist don't do therapy, but some do.

The most important thing you need to ask yourself after the interview is - Do I feel comfortable with this person? If not, check another one out. Remember it's you who are employing them.
