Avantages
Coworkers were really nice. Healthy work-life balance. You can get compensated well if you fit the culture.
Inconvénients
No upward mobility unless you curry favor with the right people. Everything depends on your relationships with the British men running the company at every level. All decisions get made from London, including benefits/HR for the ~100 employees in the US despite no one in London understanding private health insurance or 401k. The leadership team seems to genuinely care but is also incompetent, defensive, and extremely emotional. And no matter how good you are, you won't get a >3% raise unless you bring them a competing offer, which means even star employees feel unappreciated.
