I had an interview round for interning as a software engineer, after an aptitude round in our college.

Some experiences from my resume were discussed for the interviewer to get a grasp of my tech understanding.

Then, unlike as asked to other interviewees, I wasn't asked about the subjects I was interested in during my semester.

Asked: basic concepts of programming, uniquenesses of C++ and Java, and some Math concepts.

Asked to elaborate about whatever I had learned in C++, like polymorphism, pointers, and some applications.

Then, some perplexing questions on the same were asked to test my concept clarity and speed.
