4 rounds of technical interview, 1st written programs, 2nd ,3rd technical and again 4th technical comes a lady entered clearly to reject the person, full of attitude laughing when answered the question , giving arrogant smiles at the answers, even though she did not have idea of many of the technologies I worked on. I might not know the answers of the questions, but that's not the way to laugh at others working as a professional in an organization . Overall worst experience with her never seen such lady other round people were good though.
