The first round comprised of 50 MCQ questions including aptitude, logical, C output questions, and technical portions (Test Duration: 1 hour): Quantitative aptitude and Logical part were much more predominant, the questions were more intuitive and not typical paper pen/formula based. They were not very difficult but were very tricky. Suggestion: I would suggest doing practice from sites like GeeksforGeeks, Indiabix, etc. as it will give the confidence to solve problems. The technical aptitude part covered questions from computer networks, operating systems, data structures (particularly tree), digital electronics, and questions from microprocessors & other electronics topics. C output questions were also there. Suggestion: I would suggest doing quizzes from GeeksforGeeks to get in touch with all concepts of C and other subjects.
