What
@cara susanna said is so true. It will vary widely from site to site. Some sites shuffled me between multiple interviewers who asked a set list of questions (e.g., why are you interested in this site, tell me about a difficult case, tell me about an ethical dilemma you have encountered and how you handled it, interpret this MMPI), other sites were more relaxed, and they barely asked me any questions – we talked about football, cats, and what it was like to live in their area of the country. Also the list of questions – you definitely want to have this ready, and have a lot of questions on it. Sometimes during the interview, questions you have for the site will get inadvertently answered, so you want to make sure you have plenty of back up questions. Or there may be a group Q & A with the current interns (or the TD), and the other applicants may ask the questions you were planning to ask, so again, good to have back up questions. On one of my interviews, one of the people interviewing me said, "I let the other psychologists ask all of the technical questions. So I'm just going to answer your questions. What questions do you have for me?" So for a 1/2 hour, I had to ask him questions. Luckily, it was my last interview, and I had quite a few questions on my list and committed to memory, but still, not my favorite interview. Another good reason to have a lengthy list of questions – you may get interviewed by 3–4 separate people, and you will want to ask each of them questions. Sure, you can ask them some of the same questions (e.g., what are they looking for in an intern), but you there are some questions you don't want to ask multiple times (e.g., what is a typical day like at your site). I even had two separate lists ready (one for the interviewers, and one for the current interns). Because these questions will vary somewhat.
