I applied through another source. The process took one day.

I was interviewed at the Bengaluru office for a back-end Java developer position. The interviewer looked to be in a bad mood. He was constantly searching for questions on his laptop and gave almost no time to think. It was more like a viva in lab exams, not an interview where the logical thinking ability of the candidate is tested. Every time he asked a question, I gave brute-force solutions. He neither looked convinced nor asked to optimise the solution. Like I said in the beginning, it was more like whether I had seen the question before or not. There was no logical thinking at all.
