Going to bars alone is awkward as a girl, and you need social skills for people to want to take you to the bar with them.
All joking aside, I did go out all the time in college (part of the reason for my GPA) but the informal bar scene is really not like an interview. There's nothing at stake. I still haven't figured out the art of the interview. That intricate balance between talking about and selling yourself and coming on too arrogant/not listening.
I guess the bar scene is different for guys and girls. As a guy, you definitely have to learn to sell yourself and not come on too strong to a girl. Maybe you can try to get some numbers from dudes at a bar?

I'm full of awful advice that involve alcohol.
