I applied through college or university. The process took 3 days. I interviewed at Deloitte (Noida) in Aug 2017
Interview
First round was a AMCAT aptitude round. Questions were pretty basic and easy but there was a sectional cut-off and a range for right answers.
Second round was a GD round. Confidence is the key here.
Third round was face-to-face interview. Interviewers were pretty experienced and helped the candidates to ease into the interview. Questions ranged from moderate to hard.
