Mars – Why Work For Us?


In 1911, Frank C. Mars made the first Mars candies in his Tacoma, Washington kitchen and established Mars’ first roots as a confectionery company. In the 1920s, Forrest E. Mars, Sr. joined his father in business and together they launched the MILKY WAY® bar. In 1932, Forrest, Sr. moved to the United Kingdom with a dream of building a business based on the objective of a “mutuality of benefits” for all stakeholders – this vision serves as the foundation of the Mars, Incorporated we are today.

Based in McLean, Virginia, Mars has net sales of more than $33 billion and six business segments including Petcare, Chocolate, Wrigley, Food, Drinks and Symbioscience.

The Five Principles of Mars

The Mars Five Principles of Quality, Responsibility, Mutuality, Efficiency and Freedom are the foundation of our culture and our approach to business. They unite us across geographies, languages, cultures and generations.

Our Five Principles are synonymous with Mars and have been guiding Mars Associates throughout most of our company’s history. Every day, we do our best to put our principles into action through our work and our relationships with our consumers, customers, business partners, communities and one another.

At Mars, we deeply believe that everything we do can mean more. That’s why our objective is to make a difference to people and the planet through performance. We do that in line with our values that have been with us for decades; by putting our Principles in action.

And because we are a company that is about more than just profit, we look for Associates that seek to make the opportunities they get here mean more. More to themselves and their own career, and along the way, more to the people and the communities they interact with.


Contributing positively to our environment and local communities is critical to the way we do business at Mars.

A mutually rewarding experience.

Work. Realize your ambitions. And realize there’s more to being in business than just making a profit. That’s the Mars philosophy. And the opportunity we offer every one of our Associates. An opportunity to take what you do and make it mean more for you, for those around you and for the planet.

What you get here is challenging, interesting work. You get the tools you need to do a great job and you get to have the best possible people on your side to help you do it. And at the same time as getting to find ways to do business better today than we did it yesterday and driving a great career, you also get to build a more enlightened business and drive sustainability.

Because it’s never just about a single person, a single project or a single brand. It’s about how you can grab everything that’s within your reach here and use it to pursue mutual, long-term gain. It’s about having ideas. And ideals. Being prepared to risk failure because the promise of success means we’ll all be a little better off. It’s that mix of integrity and ambition that makes Mars such a special place to work. And why working here is always about more than just a job.

    Management Development Programmer Interview

    Anonymous Employee
    Anonymous Employee
    Application Details

    I applied online. The process took 2+ monthsinterviewed at Mars in January 2015.

    Interview Details

    Filled in the online application form, completed the numerical and verbal reasoning tests then got invited to phone interview which was held 2 months after originally applying.
    Fairly standard competency based questions. The email will tell you it will last for 40 minutes, the person on the phone will tell you it will last for 20. They read through a script telling you your examples should be recent and can be academic, personal etc etc.
    The woman conducting my interview sounded like she couldn't have been less interested. She was very formal, robotic and cold. One of my answers involved divulging that I had recently lost a close family member; adding context to one of my answers. She pretty much glossed over that fact and pressed on with the next question. Very unwelcoming person/tone of conversation.
    I don't think I would have accepted in the end had they made me an offer. I have another interview lined up; it's less money but I've been more excited about it than Mars. I also didn't like the fact that they never seem to respond to anything on their MarsGrads Facebook page, unless I can only see limited posts because I haven't liked it.
    The advice I was given at the end of the phone interview should you get through to the next stage is to really research Mars and really think about why you want to work there and what tasks of the job you would enjoy doing.

    Interview Questions
    • All fairly standard, she asked me 4 or 5 questions.
      Obviously; "Why Mars?". Why the MMDP and not a different programme, some variation on "what are your strengths/what are you good at?", "name a time you had to support someone in something new- what did you learn from it?", a variation of "when did you do something new/alone, and what did you learn from it?"
      Answer Question
    No Offer
