Seems like you have to be lucky to get a proper interviewer. From what i have heard, it is a mixed bag. Some interviewers are easy to handle and some of them are difficult. Depends on whom you get as interviewer.

I interviewed with 12 people, some in groups, some 1:1. The interview was very organized with an agenda and everything. They have security checkpoints, but you could actually just walk through because the card reader is not attached to a door. Hmmm. There are several other painless but pointless formalities the employees go through. The people are friendly, helpful, and nice. The culture is huge, disjointed, and disorganized. The campus is nice and there is a cafeteria and gym on site.
