I talked to a recruiter at my university's career fair and he sent me an email telling me to apply for the position. I received an interview offer a few weeks later. The interview was very professional and strictly behavioral. It seemed like the interviewer already made up his mind in the middle of the interview since the total time of the interview was only 15 minutes (10 minutes of questions, and 5 minutes of me asking questions). That was rather intimidating. He said that they would reply within 3 weeks for second round interviews.

Applied Online and spoke to a recruiter at a Career fair. Got an interview 2 weeks later. It was a Behavioral Interview, 1:1 setting. Questions weren't too difficult, mostly describe your experiences and why you would be a good fit for the company. It's been almost a month since the interview and I still haven't heard anything from the company.
