Pros
The unlimited PTO is real, and line managers encourage you to take it. Individual teams / managers are supportive and positive. No set schedule or deadlines, and radical developer freedom (more on this in the cons).
Cons
Fetch has leaders who are absolutely convinced it's the best place to work in the world, and they had me fooled for a while. They tell you they care about your wellbeing, and the wellness coach does. However, they impose unreasonable standards for app performance (sometimes outside of the engineer's control) and expect a level of urgency that is completely unhealthy. Multiple times the entire tech org was expected to work through the weekend because the CTO said so. The overwork would actually be tolerable if it weren't for the public humiliation. The design reviews are really just a chance for the CTO and his favorite engineers to talk down to people and make them look/feel stupid. The CTO has also openly stated that he doesn't care about how he makes you feel and that engineers are expected to tolerate any abuse he dishes out at any time, and how he delivers that "feedback" is irrelevant. It's good pay, it was a good team, it had good benefits, but it will never be worth being publicly humiliated over the tiniest mistakes and being expected to produce perfect work or be shamed for it. There's no concept of improvement here, if it doesn't match some arbitrary standard set by the CTO, it goes in the garbage.
