At PBA, a lot of the girls had purses and the guys didn't carry anything around.
Heck, I had a backpack AND a suitcase on top of all that!!! (I came straight from the hotel and Janell was gracious enough to let me store everything in the office while I interviewed)
I went into the interview with only one of those leather-folder portfolios with my resume and a pad of paper + pen to write down questions and info. 🙂
