Pros
Fantastic culture. It's a fairly laid back environment with great people who treat everyone as their equal. As the office manager, I felt valued and appreciated by the executive team as much as individual contributors. I can't say enough about the culture. They encourage you to try things. Mistakes are not things you tend to get in trouble for, but instead learn from. Failures mean you're taking risks and that's meaningful to them, Benefits were good, PTO started at 15 days and went up from there. After 4 years I had close to 30 days of PTO. They don't roll much over - they want you to take your time off, and they don't expect you to pick up your phone or respond to email while you're off. I was laid off when they committed to a more remote focused model. As the office manage, that cut my role significantly.
Cons
They don't always have consistent processes and procedures across the org, which for the office manager can be maddening, since I often had to sync between multiple teams doing things differently. No job is perfect, but I'd rather work for a place with some frustrating process systems than a negative work environment.
