It was 4 technical rounds of interview. The questions were not so difficult if one knows their way around development in test. Everything went well, at least from my end. But the whole process was hectic and took a lot of time and energy from schedule. The kind of work which is done practically in your daily job, doesn't concern them. Their interest lies in arrays question only. It doesn't effect them that how technically viable you are and they won't be interested in asking questions around latest technological advancement in Automation+Devops. It was blow for me that they rejected me on some unknown grounds because I cannot recall a question which I was not able to answer, be it OS, DS, Arrays, Puzzle, Test scenarios, or any other question.
