dont overthink this...
bring what they ask for in a nice binder/folder. Dont present anything else unless asked. Keep this simple. we dont want all the extra crap you have, just more to weed through later. You aren't the only interview today....
when I interviewed a few years ago..I kept all my other extra stuff in a binder in my bag along with my latest logbook (was asked to bring it...odd for corp interviews)...it takes up less space than you think - plus, what else do you need in your bag for an interview anyhow? Oh, leave the cell or crackberry in your car.
that way if they ever asked for something, you can have it all! -- without being upfront and looking WAY too excited. Definitly dont show up with your whole life on paper in front of you -- wierd...
relax, they are far more interested in YOU. If you have to get some obscure paperwork/information to us later nobody really cares!
sell your experience
be neat but not startchy. take off your coat if its more comfy that way.
be a guy everyone would want to travel 10 days with (most important)
sell your stability and your interest in staying local
dont exaggerate
have some real non-flying hobbies you can share about. (in other words..a life)
dont put down your current employer - we all know why people leave crap flying jobs.
dont put down/underestimate your current equipment or position
dont pry too much into pay/benefits/QOL etc unless its offered...you should have a clue about this beofrehand..plus save that for the later/final interview.
definitly send a thank you letter - get everyones name.
be relaxed and confident, even laugh a bit... If offered a water, etc...take it!
Dont follow those airline interview advice books. Nobody gives a shat what color tie you wear. Kit Darby is a dip$hit.
keep in mind you are there to check them out just as much as they are looking at you. I have interviewed places that, after 30 mins, I knew I could not work at..so it goes both ways.
Good Luck!
