It revolved around SQL, DBMS, DSA, OS only. And was quite easy, I was asked to implement stack data structure and couple of SQL queries. Afterwards, I was asked OS concepts like virtual memory, semaphores, mutex locks etc. Some basic relationships of databases and scalability of databases.

There were 3 rounds, 2 technical and 1 managerial. Each technical round lasted 30 minutes. Questions were mostly from projects and skills on resume and popular DSA questions. The managerial round was 10 minutes long, the interviewer mostly focused on my perspective of the company and my experiences with projects and teamwork. All the interviewers were very friendly and maintained a comfortable atmosphere for me to be able to think and answer clearly.
