YOE - 3.5
Past experience with a product based fintech.

There were in total 7 rounds of interviews.

1. First round was an online assessment taken on karat. Had few mcq type questions to be answered and 3 coding questions out of which atleast 2 are to be completed. Duration of test was 1hr. Got the feedback that test was passed the same day and got invite for next 2 rounds.
2. The next round was standard dsa round one question started with LC easy kept bumping the complexity top LC medium/hard. I exactly do not recall the question but it was a graph question.
3. Next round was system design round. They gave me specs for something in their product and asked me to first design the MVP and than scale it. Was a really nice and enriching round didn't felt like an interview but a discussion with a teammate. Was taken by a senior director.
4. After the above 2 rounds it took almost a week for the further communication and got a call saying they will be having next 4 rounds in one day after a week. The first round out of that was a LC medium DSA round 2 question asked.
5. The next round was a code review round where for the first 15 minutes they explained me the specs and later gave me the pull request on github and asked me to assume the person who wrote the code was not in front of me and I need to review the code, add comments wherever necessary checking the logic, best practices, etc. This was the first time I saw a code review round in any of the companies.
6. The next round was a resume deep dive round where I was asked to pick one of my project in my professional journey and explain it in and out. Was asked a lot of question why this and not that etc. Was taken by an engineering manager.
7. The last round was sort of a behavioral round taken by head of India engineering he asked me to self evaluate myself on all the rounds so far, which was tough, what would have went better if I had more time. This was just a short 20 minutes discussion.

Got reply on the same day that they will be rolling out the offer. Got the offer letter in next 10 days.
