I only had 1 round which was conducted virtually on MS Teams. So, the interviewer started off by asking me to give a brief introduction, the projects that I have done, and how I spent my college days. I was asked what language I was comfortable in (C++). He gave me a coding question based on anagrams of strings. And asked me for 2 optimizations for the solution that I provided. Rest of the interview was full of theory questions based on CS fundamentals. Although I had prepared for subjects such as OS, DBMS, I was surprised as the interviewer was focused more on theory unlike a complete coding interview (giving a lengthy question and asking for optimizations). So be prepared for some uncommon questions and make sure you know the basics of your favorite language well !!
