Take a tour of the Mars Chocolate office, where life-sized M&M's greet you at the door with free candy

Working for a candy company can be pretty sweet- especially if your employer is Mars.

According to employees at Mars Chocolate - a segment of the $33 billion Mars candy, pet care, and beverage company - the free Snickers and M&Ms aren't even the best part of their job.

"Mars Chocolate is a truly unique place to work," one employee told Business Insider during a recent visit to the Hackettstown, New Jersey, office. "Everyone is passionate about the work they are doing - and the people are incredible. We are one big family and that's not something you get everywhere."

Mars - which was ranked on Fortune's "100 Best Companies To Work For" list in 2013, 2014, 2015, and 2016 - employs 72,000 people worldwide and over 25,000 in the US. About 16,000 of those global employees work for Mars Chocolate.
