Pros
If you are friendly, smart, outdoors-minded and ecologically-conscious, you'll find many like-minded co-workers and gain quite a few friends. The people at Patagonia are great regardless of wether you're in retail, wholesale, or DTC. You'll have great access to product and good opportunities to provide subsidized service outside of the workplace if you wish. There's (mostly) good management at lower and mid levels and the pace of work could be described as busy, but in a good way. If you so choose, there are ample opportunities to acquire new skills with movement from position to position. At lower levels, movement upwards can be somewhat quick if you know whom to talk to and how to position yourself. If you rightfully gain the trust of your management team you may gain some autonomy in your role, which can be gratifying. Once abilities are demonstrated, Patagonia allows one to somewhat define the convention of their role.
Cons
Patagonia is a popular company which is great for stability. But that popularity gives the company a huge amount of leverage over its staff in terms of advancement and compensation. If you don't believe that pay is adequate for a given role, there is almost certainly someone else outside of the company (or inside) that would kill for that same opportunity, perhaps for even less pay. Be prepared to accept woefully low compensation (comparative to industry standards), and know that opportunities for raises are non-existent. Also know that the company places more importance on teamwork than individual importance (that emphasis is not necessarily bad on the surface). However, if you're a top performer, be prepared to have that performance overlooked and outweighed by office politic when promotions/opportunities come around infrequently as they do. That trend alienates good talent and causes the undue loss of real contributors. Communication from the top down can be inadequate at times and company and departmental direction can seem murky at best. However, that may be said of most any business growing at such a pace (Read: not Patagonia's problem alone).
