I applied online. The process took 1 day.

Round 1: tail -f kind of logger using websockets Round 2: Browser automation without using automation frameworks Round 3: Managerial Interview Round 4: Director Interview Despite my good performance in all the rounds, i got a rejection mail without any feedback. Don't know what these guys are looking for.. I would advice you to not waste your time taking such interviews

It was a tail -f type of logger system.
