Phase 1 (Online Objective round): Set of 50 simple MCQs on C++, aptitude, and logical. Only those who cleared the objective round were allowed to sit for the subjective round. Phase 2 (Online Subjective round): In this round, we had to write the whole program along with appropriate comments. The code should contain explanations wherever required. Many students who wrote the correct code and passed all test cases were not shortlisted because they forgot to write the comments. You could even include some edge cases in the comments and how they are being handled.
