Wal-Mart is an oft overlooked corporate entity that presents many career opportunities and is steadily growing!
Pros
Wal-Mart allows for vertical as well as horizontal employment advancement. You have the opportunity to try many different disciplines within the company, each with promotion opportunities, and promotions often come quickly for enterprising individuals. Corporate sponsors many learning opportunities for individuals not possessing a degree to have the same opportunities as their peers to apply for a position in another section of the business, be it technical, business, communications, merchandising, etc.
Cons
There is a lot of negative press concerning the company, being one of the largest retailers (10K+ retail units globally) and employers (almost 2 million employees globally) in the world. It is not always easy to acknowledge your employment at the corporate level to others without being forced to defend unfair assessments of the company's actions or inactions. There is also some disconnect between the associate in the filed (at stores and distribution centers) and the corporate headquarters hat is being remedied but still exists, in terms of new processes and practices not being communicated with a true understanding of the audience that will be required to execute them.
