They will come to your class and hand out slips of paper to get your contact info. Then they will call you and invite you to an informational meeting somewhere on campus. When you go, there will be several other students there but your interviewer will probably ask one/some of them to leave before they are finished which means they don't consider them a good candidate for the job. Then, if you are picked, you get to do another phone interview with the same interview. If you are picked after that, you get to do a reverse interview with an executive (higher level) member of the company. It can seem scam-ish, but from the research I've done, you can be successful and make some money and also get some good experience if you're willing to work hard and put effort and time into it.
