Lengthy process and very gruelling. Mostly case based questions were asked. Important to be able to think on the spot and great with back of the envelope math. Had a written round before that as well. The time to respond by the company after interview is fairly long. Had multiple rounds of interview. It is surely not easy and its best to go prepared atleast about Google and products.

Got reached out to by a recruiter. Passed the screening call last week. rd1 interview is coming up this week (11 days after). Apparently only 2 rds of interviews this process. Though the 2nd interview consists of 2 45min interviews in one.
