After the primary, in-person interview at my college, I was flown up to Redmond, WA with all expenses paid for a round of on-site interviews. There were 5 interviewers and each person was prompt, made sure that I had everything necessary to begin the interview, and polite throughout the entire process. Although the questions ranged from behavioral to analytical, help was provided in the entire process. Overall, the process was extremely streamlined, from initial communication to the end of the interview day, with perks like taxi vouchers and dinner budgets. This was the best interview logistics I have ever hard.
