Pros
The starting wage is decent considering they don't require experience in anything, the raise schedule is explained to you before you even start, and they actually give raises following that schedule.
Cons
In the specific warehouse I was in, management was totally inept. You could ask one manager, get an answer, and then you could get another answer from a different manager. (This is about serious, warehouse-affecting things like sending 180 cases of ibuprofen instead of 20, and then they wonder why inventory is always so messed up. When a lazy employee asks what to do, and gets an obviously wrong answer from the first manager, I bet they don't try to find a halfway competent response from someone else. They just do the wrong thing resulting in aisles overflowing with product.) You can't trust much of what you're told. During the hiring process, they told everyone in my orientation class that the schedule was set for the year, we'd work four ten hour shifts, and overtime is available if you want it. On my first night, our shift was moved back, and we had to work a few hours of mandatory overtime (and this happened almost every single night I worked there including one 16 hour night). Within a few months, we were told the schedule was changing, so we'd all be working five ten hour shifts (which were generally 12-14 hour shifts rather than ten, but they still call them tens), and then they took the set schedule away in favor of putting up weekly schedules in the break room. Management complained about workers going to the bathroom outside of break times in pre-shift meetings. They hired me for one job and put me in a job I wasn't comfortable with after a few weeks. Despite multiple requests to be put back (and assurances that they would), they wouldn't do it. Your job is dependent on production numbers, and yet the people in the office who put the production sheets into the system often mess up the numbers, and you'll sometimes see petty politics playing out by way of people in the office intentionally putting numbers in wrong, making someone's production lower than it should be (or higher than it should be). The whole thing is a mess. It's one of those jobs you only want to stay at as long as you need it, and you should only take if you don't have another option. The demanding work is fine, but the constant issues and disrespect that came from the management in the warehouse I worked in made it a very toxic situation. Walmart is more respectful of their employees than the distribution center I worked in was.
