I interviewed on December 2020 through a consultancy. The interviewer was very rude. He asked a few questions on Selenium and REST-APIs. When I tried to give examples, he was not interested in it and he also said just tell me the Definition. He talked in a condescending manner which made me feel patronized and Insulting. I think ZS should provide soft-skills training to their employees; Perhaps that would help. I had already made my mind after the interview that if I got an offer I will reject it or use it to get another offer. This already reflects on what kind of people are working there.
