We've had classes for about a month now. We signed up for clubs about 3 weeks ago, and started recruiting 2 weeks ago. Just as it seemed like I was getting adjusted to the course load, recruiting demands really picked up. With company briefings, schmoozing, company office hours, school run career management, cocktail hours, and industry sessions, I'm spending about 4-6 hours a day on average for recruiting. This doesn't include time spent on follow-up emails, additional contact (informational phone calls), or informal visits I'm planning to firms in New York and possibly San Francisco.
All these events are just banks. You definitely need to decide pretty quickly which area you plan to focus on. There are often 4-5 companies presenting at the same time. There's no way to can up with 40 firms from several different industries if they will all be in campus 3-5 times in the fall for additional events, cocktail hours and the like.
When they released the first tentative recruiting schedule a few weeks ago, I saw that basically all the top banks were recruiting on campus, but was disappointed that Credit Suisse was not coming. I have previous ties to that firm from my days as a lawyer so I planned on initiating contact on my own. I now realize that this was a silly concern. There's simply no way to pursue positions with the 40 banks that are visiting campus. In fact, I spent some time last night dropping briefings I signed up for a few weeks ago. You gotta start making choices right away; there's just too much going on.
