Pros
Typical start up perks. Hybrid environment to go into office twice a week, free snacks and drinks, there were free lunches, but that's being phased out, unlimited PTO. Most people are nice enough there, but there are too many changes between people leaving and new people starting to know who is who.
Cons
It's a startup, so you're going to work and work and work and never really feel satisfied. You will find yourself eating lunch at your desk (or just skipping it all together) to get caught up on your work. Meetings I am in you're going to hear a lot of people trying to ask clarifying questions to get more answers about what this #1 priority is. If you manage to schedule some time off, by the time you get back, you're already burnt out by the end of two weeks again and looking forward to the next time you can get away from work. My goals that I set are a joke since by the time the next quarter rolls around, most of what I WAS working is now no longer what I am now. I find it incredibly difficult to keep focused on my career and where I want to head next. We are so busy attempting to attain the next customer milestone that was promised by someone that I've never even met that you will find yourself on "death march" projects where the sole focus is to just "get it done" and then there will be time to focus on the things we need to do to fix things so they are better for next time. But the next #1 priority comes while the last one is still there, and this just keeps happening. We are using either outdated software or stuff that has been built in-house, and we can never get an opportunity to deal with the core issues. If you're lucky, you will not be managed by a micromanager, but you will inevitably be dealing with a micromanager on some level when they reach out to you since their employee stating you were a "blocker". Be aware that even though this is a start up, we've inherited everything legacy from CFN.
