Pros
Chances are, any people you will work with directly are pretty great. But that's genuinely true of people everywhere. You'll get a lot of socks and t-shirts, so if you don't have an Old Navy or similar close to where you live, that's a definite plus. Everyone is constantly doing and learning things for the first time, so you will have ample opportunity to make mistakes and learn.
Cons
You will be significantly underpaid, and not in a way that's cute-because-we're-a-scrappy-startup anymore. Your managers will either do what they can to help you, or do what they can to help themselves, and neither of those will be enough, because Jobber is a sales organization, not a product company, and this is reflected in nearly every decision that is made. Not that you will necessarily know, because upper management & executives will happily make decisions that undermine or overrule other employees with no notice or explanation. Jobber cares much more about winning "best place to work" awards than it does about actually making it a good place to work (see the first point above), and is absolutely 100% committed to being politically and socially "neutral". Maybe ignoring the world around you is good for business, but it sure makes people who work for you feel like they don't matter. If you learn to keep your mouth shut about it you will do fine.
