I'm sure you can get specific gouge on the web, but the most imortant interview tip that I would pass on is to be well rested the day of. Since pilot interviews usually involve travel and maybe time-zone changes, try to arrive early on the day before the interview. Study if you need to, but put the books away at dinner time, get a good meal, a beer (ONE beer), and go to bed early. Also do whatever stress reduction activity you prefer; stretch, jog, lift, whatever.
I figured this out because I've alawys performed better at interviews where I didn't really want the job...no real pressure

Since you really want this job, try to get some of the stress out of the picture.
