The interview process moves very quickly once it starts. I was initially told it would be 3 rounds of interviews. I did the 3 rounds in less than a week. After that it took them over a week to come back and say they were going to add a 4th interview. I then did that interview as well. After the 4th interview I was told I didn't get the job due to lack of knowledge in a certain area which should have been noted in the other first 3 interviews so overall not a great experience.

The interview went well, but the process through the human resources group and through upper management (for approval) moved very slowly. The hiring manager and Director were great, but new senior level management at the company have moved toward a micro-management style of leadership which dramatically increases decision making timelines. I was offered another position about the same time as this offer and accepted the other offer instead.
