Pros
The only pro for working at BK is that the compensation is very fair, and their bonus structure adds nicely to your earnings. However, management will try to knock your bonus percentage down by not agreeing with blatant data-supported results. And the coffee and soda was free. That's about it.
Cons
If you are the type of person who wants to do nothing but live for your employer, then Burger King is the place for you. They literally drive employees into the ground with how much they over-work them. If you expect a normal work week where you can put in 40, maybe 45 hours and actually have a life outside of work, then don't take an offer from BK. You'll be expected to work a minimum of 55-60 hours in the building, and then you'll be expected to work most evenings from home and occasional weekends. If you don't comply with these efforts, you'll be ousted and considered to be "not a cultural fit." Advancement within the company is completely based on a popularity contest (and I was told this from senior and executive management). They will tell you that they "pay for performance," but in reality they only think you're contributing if you're the last one to leave at 10pm. Another item I was told my senior management is that they keep note on who spends the most time there - as if that had any correlation to performance. The run very lean, so lean that you must buy and bring your own office supplies (including pens), so don't be surprised as they eliminate positions and thereby overload everyone else because they are too cheap to pay enough people to get the job done. Voluntary turnover at BK is super high, so high that one of their Major Goals for 2014 was to drop Voluntary Turnover below 50%!! That means that over half of the company leaves every year on their own terms - what does that tell you about the work environment and the "culture?"
