The interview process consisted of three rounds:

1. Recruiter Phone Call: It was mainly concentrated on my profile review and to see if I was a good fit for the job role. Once I cleared it, the recruiter was quick in setting up a video interview within the date ranges of my choice.

2. Manager Video Interview: The video round was all about reviewing my technical experience relevant to the job role. The role was primarily based on Java application development, so I was asked questions about some object-oriented concepts. Then, there was an algorithmic problem to solve.

3. On-Site Interview: Once I cleared the second round, the recruiter was quick and very clear in scheduling the on-site. The on-site was a six-round panel. There were questions about dynamic programming concepts, breadth-first search, connected components, projects review, SQL queries, query optimization, and some behavioral questions.
