In my 8 yr career, this was the worst interview I faced in terms of the questions and the process. There was a written examination which I cleared and was then called for a F2F discussion. After asking mere 4 questions (in a span of 10 mins) out of which I answered 3 of them properly, I was asked to leave. From what it seemed, it was just an interview to show that the company is hiring without actually having any intention of hiring(This is my personal view). My advice to the management would be to respect the valuable time of a candidate.
