Pros
Not being from the midwest, I didn't grow up with Walmart and assumed it was an evil corporation bent on putting small competitors out of business and destroying community-based employers. It was surprising to find such a relatively benevolent company lurking behind the sensationalist headlines. While there used to be odd cultural hangovers (like not having a website until around 2000, a conservative dress code, no alcohol at celebrations, etc), the company has really loosened up over the last decade, celebrating diversity and welcoming new ways of thinking.
Cons
When you're this big, both mistakes and wins tend to be at scale. While there are folks walking around with 30 and 40-year badges (what other company can boast that?) I have also seen layoffs happen to folks regardless of tenure or performance, which is both disheartening and illogical. Generally, the company tends to take a lot of shortcuts, outsource solutions, and neglect to invest in long-term tailored solutions, leading to most teams investing huge amounts of resourcing to keep legacy operational and technical hacks running because they've become intractable.
