Worst company to waste your time on. Following are the experiences: 1st stage: 1) HR called at 13:00 to inform(not ask and with a demanding tone) me that the interview was at 14:00, for which I received no call till 14:30. 2) I called HR who didn't know at first who i was, then told me he will call shortly only to receive a call at 14:45 to ask for a call at 15:30 for which i got a call at 15:45. 3) The interviewer asked some question on the mathematics for robotics which he didnt knew himself (was asking about inverse kinematics but didn't knew himself what it was rather stuck on definitions of some theorems) NO EMAIL WAS RECEIVED AFTER THE INTERVIEW OR BEFORE 2nd stage After 4 days again the HR calls in to tell me the time not to ask: One guy from their software team calls after a few hours, and to my surprise starts asking about computer vision and mainly python and when i ask about the relation of this with my job profile he starts telling me how it used, which although i knew and answered his questions to my satisfaction after which he told me about the next interview round and what is expected of me. Still no email communication till this point, I asked the HR telephonically got told interviews underway. This company dosent know how to conduct itself, without going on to personally attacking anyone, i would say just keep away from them.
