Persistent Systems Entry Level Software Engineer interview questions

As Persistent came for on-campus placement, the first step was giving the online aptitude assessment. After clearing it, we received a mail regarding the interviews for the base package. The interview was conducted on the Amcat platform. It started with a formal greeting and tell me yourself question. After that questions were asked on my projects. Slowly the interview moved towards the technical part where I was asked questions on DSA, OOP, CN, OS and DBMS. The interview went on for almost an hour. The questions that were asked ranged from easy to medium level.
