It was an on-campus Intern + PPO offer. There were two roles, C Developer & DevTest (Java, Python, C++). I applied for DevTest. There was 1 OA on HackerRank in which there were 3 DSA Questions of Medium Level and There were some MCQs with 90 min Time Limit. After the OA, there were 3 technical interviews conducted on Zoom Platform with HackerRank's CodePair link. Round 1: (50 Minutes) Interview started with my introduction. After the introduction, Theoretical Questions based on CN, OS followed for around 20 Minutes. After that, One Easy Question Based on String & HashMap was given. It was supposed to be fully coded.
