No prior information was given before scheduling a round about what it is going to be. Expected a lot from this but after attending all the technical rounds (3) this has to be said which made it even more frustrating. Interviewers were always 10 minutes late or all the rounds, extremely egoistic and negative and didn't even gave their proper intro and started shooting with technical questions from the first minute. Once they are done with their questions, they simply end the call. All the 3 rounds are mostly same. In the last round I was so frustrated because the interviewer was not able to clarify his questions. Really so much waste of time after those 3 rounds (almost 3 hours). Interviewers should be well prepared, should have the ability to connect with the candidate and should clearly bring forward their questions. Feeling lucky after this thing is over that I dodged a bullet.
