Avantages
Paycheck is great, people to work with are generally very intelligent, positive and professional. Many positions are work from home or at least hybrid. Continuous learning is encouraged. Since the company is technically British, it is very inclusive and has several networks to ensure inclusion (although some such as the menopause support group are UK based which isn't surprising as the US doesn't typically care about such things though they should).
Inconvénients
The workload is often insane to put it mildly. You are expected to sort of "do everything". When you are encouraged to speak up if you have too much work, they pretty much tell you "well you just have to figure out how to get it done because we have to give you more work". There is blatant favoritism. Those who are liked are praised for giving detailed answers on calls and granted a month off of PTO while those not as well liked get grilled when they ask for one day off and are told "not to overthink" when they try to provide detailed answers.
