    Summer Associate Consultant Interview

    Anonymous Interview Candidate in Stamford, CT
    No Offer
    Positive Experience
    Difficult Interview

    Application

    I applied through college or university. The process took 4+ weeks. I interviewed at Mars & Co (Stamford, CT) in November 2016.

    Interview

    Applied via on-campus recruiting. First round was 2 back-to-back 45 minute interviews with Senior Associate Consultants. Final round was two 55 minute interviews and one 30 minute interview with senior personnel (project managers, VPs) at their Greenwich, CT site. All the interviews had a combination of case (usually market sizing or profit estimations) and behavioral questions, with a couple of brainteasers.

    Interview Questions

    Easy Interview

    Application

    The process took 3 weeks. I interviewed at Mars & Co (Greenwich, CT) in October 2016.

    Interview

    First you have a phone screening with a recruiter. Basic Fit questions.
    I was called very soon to be flown to the Greenwich office for a 1st round interview.

    The first round is 1.5 hours. 2 1:1 interviews.
    We first talked about my resume. Then, he gave me a market sizing question.
    He tested me on an assumption I've made, but I defended it by thinking about it in another way.

    The second one also started with questions about my resume.
    Then, the interviewer gave me two brainteaser questions.
    There was a blunder with the first one because the question was a bit vague, but it was solved in 3 minutes. I couldn't get the second one. When I asked the interviewer, he didn't really give me a good explanation for the correct answer. He said it was just arbitrary.
    Finally, he gave me a pricing question of a company. It wasn't a standard question you would expect at a consulting interview, and it was finance-ish.

    Interview Questions

    Application

    I applied through college or university. I interviewed at Mars & Co in October 2016.

    Interview

    The first round was a 20-30 minute phone interview. It is mostly to discuss your experience and data analysis projects. It was relatively straight forward, but be prepared to answer the question "are you interviewing with any other firms?" If you pass the first round, you travel to the office for an in-person interview.

    Interview Questions

    • Describe a time when you used data to solve a business-related problem.
      Also general questions like: Tell me about _____ on your resume. Why consulting?

    Senior Associate Consultant Interview

    Anonymous Interview Candidate in Greenwich, CT
    No Offer
    Negative Experience
    Average Interview

    Application

    I applied online. The process took 8 weeks. I interviewed at Mars & Co (Greenwich, CT) in October 2016.

    Interview

    Initial phone screen focused on my interest in consulting. First round interviews consisted of two 45 min interviews with junior consultants. I felt the interviewers were a bit unprofessional and untrained. The first gave me a riddle and brainteaser that are both known cliches of consulting interviews, and then spoke more about himself than listening to me. The second asked me to describe my background, and after nodding along for a minute asked me a completely irrelevant question about sports. We then did a market sizing question, but by that point I felt like walking out.

    Interview Questions

    • Tell me about yourself/why are you interested in consulting.   Answer Question

    Average Interview

    Application

    I applied online. The process took 3 weeks. I interviewed at Mars & Co (Greenwich, CT) in April 2016.

    Interview

    I met Mars & co. at the Columbia University career fair, applied online, and get an interview. The interview consists of a initial phone screen (fit) followed by 2 rounds. Mars responded very quickly (2 days after the 1st round, and offered me a position on the spot in the 2nd round). The interviewers were friendly and the cases were not too difficult (I have practiced about 75+ consulting cases so I'm a very experienced case solver).

    Ultimately, I decided to turn the offer down for 5 reasons. 1) The company is a sole proprietorship which I believe is not a good ownership structure for a consulting firm. 2) Career options seem limited after working with Mars & co compared to BCG or McKinsey as they are a small firm that not many have heard of. 3) The compensation package is not that great. I was offered $110k base salary with a $10k signing bonus and no annual bonus. That's pretty low for the industry 4) PhDs (I'm a PhD) start a pay scale under MBAs. I don't think that's fair as I think PhDs have a better analytical skill set than an MBA and Mars markets them selvs as an analytic heavy consulting firm. 5) The daily 1 hour commute (on way) from manhattan to Greenwhich, CT seems kind of brutal. Greenwhich is not an attractive place to live for young people like myself.

    I would be very hesitant to take a job at this firm.

    Interview Questions

    • The interviews are a combo of fit and case interviews. Study how to do market-sizing, answer brainteasers, and answer abstract questions.   Answer Question

    Associate Consultant Interview

    Anonymous Interview Candidate in Greenwich, CT

    Positive Experience

    Application

    I applied online. The process took 3 weeks. I interviewed at Mars & Co (Greenwich, CT) in May 2015.

    Interview

    There were three rounds. The first was a 30-minute phone interview with typical fit questions. The next one was a set of in-person interviews consisting of back to back 45-minute meetings with an Associate Consultant and then a Senior Consultant. Each of these interviews contained fit questions and one case. The final round was another set of in-person interviews: this time three back-to-back interviews with a Project Manager and then two Senior Vice-Presidents. They asked fit, brain-teaser, and case questions. Two consultants also took me to lunch before my final-round interviews.

    Case questions consisted primarily (but not solely) of market sizing. One of the interviewers really challenged my process at a couple of points but every other interviewer was simply supportive throughout the whole thing. The Senior Vice-Presidents that I met with were especially warm and friendly.

    Communication and coordination with HR was quick and smooth throughout the entire process.

    Interview Questions

    • Basic fit questions: e.g. Why Mars & Co? Why consulting? Tell me about yourself.
      Brain teasers: Probability questions
