The whole process took about 3 - 4 weeks. I had a phone interview with the HR person. After that, I was called in for the first round pf interviews with about 3 different people. They asked in-depth questions about qualifications and work experience.
I was then called for the second round of interviews and these were with more senior level of management and questions were more about fit with the company culture, and my career goals, etc, more high level questions.
