Linkedin is hiring like crazy right now - on the particular random day I arrived, there were at least 10 other applicants hanging around the receptionist's desk. They sent me a solicitation on linkedin (no surprise), and I followed up and had a technical phone screen quickly scheduled. They then flew me out to interview on-site about a week later and put me up in a really nice hotel. They gave me a gift bag on arrival, and the whole process felt really comfortable, which is unusual for an interview. I interviewed with something like 11 people total, some alone, and some in groups of 2. Half of those interviews were about demonstrating programming skills on a whiteboard, the other half were for demonstrating "design" skills (abstractly designing systems). There was a break in the middle for lunch in their giant, excellent cafeteria.
