To piggyback on what Cujo just said:

I attended both the NGPA and WAI events in Feb and March this year. Omni was at both conferences and it was easy to speak with them. They did not take resumes at either event but I definitely feel like the HR person there took note that I was there. The WAI event was last week, I attended on Friday and had an email with good news by Monday. I had previously applied and didn't hear anything so I feel like the WIA event helped (Although it could be complete coincidence.) I know one thing for sure......it didn't hurt.
