ABC ABC Test interview questions

The interview process typically includes an initial screening, followed by one or more technical rounds, a behavioral interview, and sometimes a final discussion with leadership before receiving an offer. excellent

The first round comprised two sections Aptitude and Technical each having 30 MCQ questions total of 60 MCQs. There was negative marking and a Sectional cutoff. I did 31 out of 60 questions. The quantitative aptitude part was much more predominant, the questions were more intuitive and medium-level. They were not very difficult but were tricky. Suggestion: I would suggest doing practice from sites like GeeksforGeeks, Indiabix, etc. as it will give the confidence to solve problems. The Technical part covered questions from Object Oriented Programming, data structures, and C output questions was also there. Suggestion: I would suggest doing quizzes to get in touch with all concepts of C and other subjects. Tips: Solve the questions with a calm mind. Don’t stress yourself during the test because you have to do 60 questions in 60 minutes. Don’t spend too much time on any question if you are not able to do it on the first attempt.
