I knew the hiring manager but still had to go through a group interview. There was a group of 5 candidates and 3 hiring managers. Spoke one at a time of interview questions.

A long process. In total I would say it took nearly 2 months to finally be offered the position. It was a general question phone interview with HR. If you pass you will then be in contact with the hiring manager who will interview you with questions he/she may have. If you pass the first round (where they narrow down the candidates) you would then be invited to do a test, a test which will relate to the job position you applied for. If you pass the test, you will then have a final interview with the people who you will be working with.
