1. There were 5 rounds. The whole process took 1.5 months before I received the offer letter. 2. The interview is to make sure how good you fit into the role, not to test if you know something or not. 3. The hiring manager was very prompt in following-up and sending updates of the process, in case if you are one of the potential candidates under consideration for offer.

It was a good interview with medium-to-difficult questions. It took 4 rounds of technical interview. You should have strong fundamentals and analytical thinking to crack interview. You need to demonstrate your experience and skills smartly and apply your skills wisely.
