The entire process consist of three rounds
Round 1 (SKYPE INTERVIEW) with a consultant
some basic HR questions like why consulting and since I belong to economics background so why not investment banking
Round 2 (SKYPE INTERVIEW) with Director
This was also simple, nothing to technical but involved a good case and rigorous discussion on it.
Round 3 (OFFICE INTERVIEW) with Partners
I could not make it up to this round but I believe this would have been a proper fit + case round as you see in other big consulting firms.
