Interviewed at Mars & Co
Interview Details – Phone interview asking about interests and experience. Then flew down for two onsite interviews. Both of the interviews were briefly about my past experience and then short market-sizing questions. Nothing too difficult but I was not prepared for market sizing questions. They also wanted my notes after the interview...which I did not expect.

I applied through college or university and the process took 2 months - interviewed at Mars & Co.
Interview Details – I was selected for a first round interview through my college. I liked Mars interviewers the most out of two other job interviews I had that day. I had two 30 min interviews. One was behavioral and case. The other one was just case interview. I didn't get to move on to the second round. I think it might've been because of how I did on the case interview--they were trying to confuse me.

Very Difficult Interview

Interview Details – After a short phone interview that was only personality and resume questions I was invited to Greenwich to interview on site. I met with three interviewers who presented different cases. Questions ranged from statistics to calculus to arithmetic. It was challenging, but interviewers were helpful.
I applied through college or university and the process took 2 weeks - interviewed at Mars & Co in November 2011.
Interview Details –
I applied through my university career services. The first round consisted of two 1:1 interviews with a Senior Associate Consultant and a Managing Director. Both started with the typical behavior questions which was then followed by a market sizing question. The questions were not too difficult, however, they did question my assumptions to pressure me a bit in defending my answer.
The second (and final) round was at their Greenwich office, an hour from Manhattan. I had three back-to-back interviews for a total of 3 hours. They were all with very senior executive people (VPs, Sr. VPs). Again, each asked me a couple of fit questions but the interview was mainly focused on the market sizing questions. and brainteasers. The questions were definitely unusual, and I thought, pretty challenging.
Overall, you need to be very quantitative to enjoy and have success in their interviews. Most of the employees have some sort of engineering or mathematics background.
