- Problems can be a bit undefined; you must be ok with ambiguity
- OKRs and various processes can be a bit hectic. No one seems to love them (though I've been through much much worse)
- There is a lot of context switching due to the fast pace of the environment.
- The company is weirdly buttoned up - and I'm not saying dress code, it's just that communication is very formal at times
I don't know if any of these are "cons" objectively, just thing you'd want to be ready to handle.
