Pros
Fun events if you have any energy left to attend them. Some really great team members who, through shared trauma, become as close as family to you. You're surrounded by people doing interesting, innovative things, which can be inspiring, especially if you have entrepreneurial leanings.
Cons
Workloads are unbelievably unrealistic. Even when my team committed to it, it was nearly impossible to make time for real lunch breaks. While you're working on the front lines, decisions and initiative were being handed down from above that seemingly had zero input from those who would actually have to execute them, sales teams/managers are complete lunatics and no one actually knows what most of them do all day, ditto for many of the "marketing" or "partnerships" people. Buildings open far before they're truly secure or ready, leaving the community staff to deal with inadequate and sometimes unsafe environments. Member to staff ratio is seriously off - in my building it was 3 community team members to 800+ members. And finally, while one of the founders is at least humble (although he did slip up and say something I found pretty offensive once about how community management could be chalked up to customer service, plain and simple - which I completely disagree with), the other has a raging god complex and drug problem. We actually received detailed instructions once on how to survive a visit by this guy to our building, and it included things like keeping the lights low, making sure the DJ played old school hip hop, and having his favorite snacks and tequila (and expensive bottle) on hand at all times. There's no excuse for behaving the way this guy does, especially when his employees are making him billions of dollars. One of the biggest reasons I left.
