2 rounds both technical, array and linkedin list questions , along with cs fundamentals. The first interview had only 1 interviewer. 2nd had 3 (one of which was a shadow interviewer)

The first round was an online assessment consisting of 5 DSA questions. I was able to solve 3 completely and the 4th one partially, which helped me get shortlisted for the next round. The second round was an online interview, where I was asked questions from OOPs, OS, and DBMS, such as: 1. What are classes? 2. What is a database, and why is DBMS used? 3. What is paging in OS? 4. What are threads? 5. What are the four pillars of OOPs? 6. What is the difference between inheritance and abstraction? Additionally, I was given a DSA problem to solve: Decode String (LeetCode)
