I applied through referral, got call from the recruiter and recruiter arranged the phone screen with Hiring Manager after that i went to in-person interview. Interview was not that tough.

HR contacted me and scheduled an interview immediately. The first round was technical, and they asked about Spring boot, Equal hashcode contract, how hashmap works, how we can create our own hashmap and the Need for REST API over other SOAP or GraphQL. In the second round, they asked the same questions, but they focused more on what I did in my company and Instagram System design and asked some basic questions.
