I applied on the website and had a phone interview(within one week) for half an hour, where I was asked questions like, Why I am interested in Proteus?, Why would you want to do this job?, etc.. After that I got an email after one week saying that I was scheduled for a Skype interview. 7 Managers took the interview. There were four interviews of half-an hour each with two of the managers and the last interview was with the senior most manager. There were questions on my research, the courses I took, what do I do on the weekends, talking about the city I live in.
