I applied through Internshala and received a call from HR for the first round of the interview. Round 1: The interviewer asked me to solve a problem based on a priority queue. After successfully solving it and explaining my approach, I was selected for the next round. Round 2: This round focused on Object-Oriented Programming (OOP) concepts, where I was asked to explain them along with their implementation. Following that, the interviewer asked questions related to Android development, reviewed my projects, and asked in-depth questions based on the work I had done.
