Thanks for the responses guys.
I went to the career fair on Tuesday and I felt pretty good about it. I had a list of 14 companies that I wanted to talk to so I did research on every one of them. Took me like 3 hours just to do that. I also took notes and wrote down questions that I had after researching them. After introducing myself, some recruiters started firing questions at me right away. So I didn't use an elevator speech all the time. But I made sure I used parts of it when they asked questions about me personally.
But like shah said, it's about who you know. I'm hoping to hear more from the firms that I have already networked with. But I'm also hoping that I made a lasting impression on the one firm that I really want to get in to.
Not putting miles on your Ferrari is like not f*cking your girlfriend so she'll be more desirable to her next boyfriend.
