THIS helped me a lot when I was looking.

I think the biggest thing is being assertive enough to ask questions and let prospective T know what you are looking for. Be sure to ask about extra contact if you think you will need that. (ie: email, phone calls, texting...etc).

I didn't do the interview well at all, I couldn't speak up or ask questions. I did get a decent T in spite of it though. I was referred by my pdoc who knew me really well.
