Started with a written test, second round was the HR interview basic questions like tell me about yourself and some questions on SEM, third round was a technical round with the SEM expert more questions on SEM were asked. Interview process was quite long however it was positive, food and snacks were provided during the interview. I believe the last round is the director round I didn't make it to that

Easy process but they take up whole day. Mostly to check English writing skills because you have to write review of 150 campaigns where you don't have any authority to make many changes.
