I talked to on-campus recruiters at my university's career fair about my experience, what i was interested in, etc. They invited me for an on-campus interview later that week. The on-campus interview was about 30min and the woman asked me some questions but also told me a lot about what she did as a sales engineer. I received a somewhat cryptic followup email about "we were pleased to meet with you, we will let you know if we have any positions meeting your qualifications." I then received a formal invitation to interview again. This time it was through a service called HireView, where i had to complete a video interview where they flashed a question for :30s then i had 1min to record my answer before the next question popped up. I then was invited for a final interview, also through the HireView site, but this time with a manager. I was then emailed a few weeks later with an offer.
