Interview took a total of 3 rounds. 1 round over the phone with the recruitment person for about 45 mins, 1 interview with the manager and the 3rd interview with the head of dept. The entire process was slow, it took more than 1 month to process. Interview was pretty casual and not tensed, HR seemed very nice and friendly. I thought I will make it through as they seemed to be very keen and it looked like a good environment and company to work in.
