I've been on three interviews so far, one was a group interview, one was a closed file 3 person panel interview, and the other was 3 consecutive one-on-one interviews. For the first two I practiced with questions from the interview feedback. I got a full nights sleep and went for my interviews. I was nervous as heck and couldn't say all the stuff I wanted. My third interview, I woke up at 3 am and couldn't fall back asleep. I googled my interviewers names and found out about their backgrounds (ie their research and where they got their degrees), but didn't practice interview questions. The rest of the night I spent fooling around the internet. I slept about 3 hours that night, and stayed up till my interview at 11 am. I was tired as heck, but the interviews went really well and I said exactly what I wanted. I think the big thing that helped me was the sleep deprivation. For some reason, when I don't get sleep, I think a lot less and therefore feel less nervous when I speak. Same thing happens when I play tennis. I pulled an all-nighter back when I was in school for finals and then played tennis afterwords, I played the best tennis of my life. I don't second guess myself as much when I don't get sleep. It also could have been I felt more comfortable with the interviewers knowing what to talk about with them. What works for you guys?
