First, I steal one of those little note pads from the hotel room, along with all of the available pens.
I then write my flight number on the bottom of the pad, attach it to the yoke to help me remember who I am when speaking with ATC, and at the end of the leg I write my flight time on it.
I repeat this all over again on another piece of the hotel scratch pad.
Do this for every leg for the entire month.
At the end of the month, I take a giant industrial strength stapler, and staple all of these little sheets of paper to the inside cover of that months Hustler, Playboy, Men's Health etc.
Then during your interview you can just pull out your stack of favorite magazines for the interview committee.
It worked for me.
On a serious note, I use an electronic flight log.
