Google

First, I received a telephone interview round, where I was rejected due to a backlog. This was quite surprising because I thought the founder of Google was a college dropout.

The interview has one OA and three technical interview rounds. Each round is 1 hour (45 minutes for DSA and 15 minutes for Googliness). In all rounds, they asked about one coding question and follow-ups depending on time.

It was a great learning experience. Although I couldn't clear the interview, I got to learn so many things about how all the concepts I learned can be applied to solve real-life problems.
