I applied through an employee referral. The process took 2 weeks. I interviewed at IBM (Bengaluru) in Sept 2017
Interview
There were three round of interviews. First round was telephonic interview with one of the panelists in IBM premises. It last for 1 hr, pure technical questions. After clearing this round there was managerial round, for me it was one same day but they do call for this round after a day or two. In this round manager will ask questions related to your domain and if he finds you suitable for position,then you are almost selected.Finially he will discuss the salary and JD in detail.
