I started the process through on campus recruiting.
Zappos really cares about hiring people that fit their company culture. Before the interview, I had to take two kinds of behavior/culture screening tests.
Afterwards, I spoke over webcam with a really nice HR representative. The conversation was really laid-back. Basically just a run-through of work-experience, behavioral questions, and what-not. This is a culture screening interview.
I passed this stage and went on to be interviewed by the manager who would be my boss if I got hired. He seemed half-asleep when interviewing me. His web-cam was tilted awkwardly so I could't really see his face clearly. He looked like he was about to doze off...even before the interview actually began.
I asked a lot of specific questions about the job at the end. He then told me that the fact that I went to X university, didn't guarantee that I would get the job, which was kind of awkward. I thought I did a good job, but didn't get the job. Not exactly sure why...
hope others fair better!
