Yeah, I agree with Johnnyx9. If you're interested in banking and you haven't decided yet, it's too late. Pretty much all the big banks have been on campus already, and some will be making their 4th visits next week. I think the prevailing opinion is that if you don't land a banking internship, it's really really tough to get a full-time offer as a second year. So, depending on the field, you have to decide pretty much right away.
On the other hand, most general management and marketing recruiters just come to campus once to make a general presentation, and schmoozing is not required, so you can decide much later and just drop a resume. For banking, and the top consulting firms, you must schmooze. Some banks have even come straight out and said that even if someone successfully bids for an interview with them, they will not make an offer unless they know the candidate well (aside from the interview).
