I trust rhyme will write a more useful post with actual hints, but for easy reference the process (in chronological order) works as follows:
1) The consulting firms that recruit on campus begin the marketing (aka "stalking") as soon as the school allows them to. At some schools, this means day 1 while at others it means after the blackout period.
2) Marketing takes many forms, such as:
- They send you a binder with info on their firm and a letter listing your classmates which use to work at the firm, urging you to contact them.
- They fund cocktails or other gatherings through these students to promote interactions.
- They send both general and specific e-mails based on the clubs you joined or your career preferences as stated in the resume book, urging you to apply and/or contact their partners (or alumni from your school) at office XYZ.
- They organize conference calls with students and current employees.
- They organize lots of cocktails for you to meet people from the different offices. These cocktails are typically invite only, although if you keep in touch with classmates from each firm (and office), chances are you'll get invited to most.
(All the above- and much more- takes place before the application deadline)
3) Once you apply (typically through their website), and assuming they like your resume, they'll invite you to interview. Note that to apply you typically need to choose a specific office.
4) You go for first round interview. These almost always involve 1 or 2 cases and some other questions (why consulting, why firm XYZ, etc.). Some firms invite a lot of people to 1st round interviews and get really selective after that. Other firms are more selective in their 1st round invitations.
5) If you make it to the next round, you'll typically need to interview with a very senior person at the office where you will work.
6) If they like you, they make you an offer with a specific deadline.
