Firstly, it's an on-campus recruitment which is of 2 rounds, first is online assessment in which the first part is of 30 core questions which you have to solve within 30 minutes, that was quite tricky because I chose research and development domain so there are questions from analog electronics, control, network and microprocessors, after this there is gamezy in which basically you have to solve puzzles, charts and there is also a game like sudoku, so that's it about assessment, after 1 week results are announced and also there are respective cutoffs of every section, only 3 students are shortlisted for interview process.
