Received an email to come to Seattle for a day of interviews after being recruited. Follow up on company's part was surprisingly lackadaisical, resulting in the fact that I had to book all my own travel and lodging. Still, my reception was very warm and cordial by each of the five interviewers: 3 specific to my prospective division, one from a parallel, possibly "competing" division (i.e. logistics & operations), and one general HR person. By and large, a behavioral interview, peppered with the occasional inane corporate "surprise" question that comes as no surprise at all. Keep your cool and remember the larger point here is a test of personality, obviously. By and large, a friendly if harmless trial.
