I was involved in a hiring conference. They had a group of us to come into a central area and conduct round robin style interviews throughout the day. It was a standard two interview schedule. If you were that impressive, they gave you a third interview right there on the spot. After that, about 2 weeks later I received a follow up call to see if I was still interested in the job and if so, when could I be available for a final phone interview. The next week I had the phone interview and then a couple days later they made me an offer.
