My total interview time last about 6-7 hours over one phone interview and two separate days. I talked to 8 different people total, almost half of them in senior management. That was probably the most intimidating part, interviewing with directors, VPs, and Sr. VPs, but surprisingly, it was pretty straightforward. Each of my interviewers asked me almost identical questions, all pertaining to my previous work experience. One of them actually went down my resume and had specific questions about each line item I had written down on my resume, which I thought was helpful since I am very familiar with I had put down. The interviewers were also honest with their own experience at the company and gave me realistic expectations, which I appreciated.
