Career Development Event

I just signed up for Career Development Symposium Event organized by the local CFA society. It seems that big companies gonna be there. The question is has anyone attended such events? It says that event gonna be networking opportunity for employment seekers.

Can you give suggestions what to do, how to maximize the benefit from attending? Is it appropriate to bring several copies of resumes and start handing them over? Who I should talk to first?

Thanks in advance
