I'm in 2nd week of training now. Bring a laptop as long as it wont be a distraction. Dont bother looking for a FAR/FC I havent opened mine once. I used the aim a little but I looked stuff up online. Bring a notebook to take notes the first day (obvious hopefully). Also, bring a voided check for direct deposit, a flight case type case for books and dont expect any free time in the evenings during the week. Like, no time to work out, talk on the phone much or watch more than an hour of tv.
For people trying to get an interview, I met one girl who was called cold after putting her resume up. No internal rec (but I think she's an exception). Calling HR people and being sqeauky is the best way to get a call besides a rec.
