I applied through an employee referral. The process took 1 day. I interviewed at Allsec (New York, NY) in Apr 2017
Interview
1st round will be group discussion-easy
2nd round will be Manager round, they just expect good communication skills and very frank of the role and salary they provide you if you join.
Interview process was pleasant an smooth. First there was general questions by managers, then group discussion. Later there was HR interview. All in 1 day. Process was real quick and smooth.
