Three stage interview. First telephone interview (some cases only). There are two face to face interviews after which they select the candidate. They also give questions which can be better explained with examples otherwise they wont make sense.
I applied in-person. The process took 1 day. I interviewed at BT Group (Bengaluru) in Aug 2017
