I had the paperwork that gets handed to them in a folder, and copies of that, my military records, logbook print out and originals of my license, passport, etc. in a 3 ring binder with a nice Comair RJ photo on the cover. The binder lets you access stuff really quick, and you can get pages made to hold business cards and photos to arrange the hard items (card holder for your license, 4x6 picture holder for passport/med). Keeps it all in one spot. They'll give you a folder with a bunch of HR stuff too. Plus when you interview elsewhere you just need to update it and swap out the cover

Good Luck.
