There were 5 rounds in total: 1 coding test, 3 technical and 1 managerial/HR interview. Coding test questions were simple only the last one was little tricky.(there were 3 questions) In my first technical interview they(2 interviewees) just asked me to explain how i had approached the coding questions of the previous round and also asked to optimize one of the solutions which I did.(the interview is taken on the same platform where you had the coding test so, your solution is written there and visible plus accessible by you and the interviewee). The second interview was mainly focused on OOPS concept and it's implementation along with explanation of one of the projects also some puzzles were asked. In the third round the focus was more on the language in which you are comfortable with, So they asked me about the new operator in C++ it's working and related questions. Asked me to design a calculator given the module of a basic calculator basically checking your understanding of OOPS and several questions on it. Virtual keyword uses and why. Then was the HR round in which she told about the company what they do and explained the timing of internship and it's duration. This was just any other HR round.
