I applied through college and had 4 rounds of interview each round was an elimination round. 1st round was usual aptitude mostly from RS Agarwal and Indiabix 2nd round was GD more of an extempore on current trending topic 3rd round was technical PI 4th was HR round and finally if you get through all the rounds, there will be an interaction kind of round with the MD Mekalai R at the company premise. All the rounds were quite easy to clear.
