Fresh hair cut, well fitted suit, and be polished.
Recruiters are judging you before you even open your mouth. Also, the prestige / rank of your school as well as majors will determine how companies show up and how may you are applicable for.
For example, obviously engineering students will have more to choose from than public policy students.
What I'm trying to say is that if you are in a position where 50+ companies are showing up for your major, you need to have a short list and a gameplan. Elevator pitch, 30 seconds to set yourself apart from the rest of the students. Fresh resumes, formatted well with no typos.
You can't spell stuff on a resume correctly, how can I trust you with a electronic circuit or a financial model.
I used to get a lot of interviews from these. If you have a good resume, you will be fine. Also, I'd attend any company information sessions.
