Pros
When I first started working at Etsy, the company felt like a magical place. Three years ago, having unlimited sick days, decent PTO, free snacks and a couple of lunches a week felt like actual perks, whereas now this is industry standard (not to mention Etsy has cutback on all of these things tremendously following massive layoffs and restructuring). The main pros I can think of is just experience. For anyone who isn't coming from a tech background, you can learn a lot here (as long as you make it your business to learn, and push your way into experiences, which is not always easy).
Cons
I had several experiences at Etsy that I felt were based in sexism and misogyny, a few of which I escalated to HR and upper management. I felt I was dismissed, and was told the issue would "resolve itself." After a few years at Etsy, I could really see that there is a lot of darkness here, at least in certain organizations. Women are not always empowered to speak up about their compensation, career trajectory, or general experiences within the company. I can't speak for the men there, so I don't know how their experience differs. I would caution any young women working here to be really tough on their managers to ensure they are receiving proper compensation. I left Etsy never being compensated for a large portion of the work I had done.
