It took more than a year and met with more than 13 people over the time. All the interviewers had same competency based questions, nothing were unexpected. They told me that I should expect the offer in 1-2 weeks but it took more than a year as I had to wait hiring freeze to stop 2 times. Most of the interviewers shared company gossip or disclosed confidential information, which I thought part of the trick to understand my attitude but later saw that it's very common in the company at every level to all employees or partners.
