There were four rounds: a coding round and three interview rounds.

In the coding round, I was asked to solve three Data Structures & Algorithm questions in about two hours. I could use any language of my choice, and I picked C++.

In the first interview round, I was asked two DSA questions, and my OOP concepts were tested.

In the second interview round, I was asked one DSA question and two database questions.

The third interview round was more of an HR round, in which the interviewer asked me about my further academic interests and future plans.

In a database, if the system crashes, what mechanism is employed under the hood to retrieve the data and cope with the database system crash?
