Went through 4-5 interviews, each of them were scheduled after I went through the previous one. Questions are fair - basically, they want to know what you are doing in your current job, and how you are doing it. They want to know how you think. Interviewers were not well-prepared because most of them were gathered last minute to come in and talk to me. This reflects poorly on the company's organization. But that's the process. They also like to call you in to talk to 1 person towards the final process, which is interesting (kind of inconsiderate for people's time in my opinion).
