Pros
Really nice culture if you fit in with your team, everyone's really chill and easy to meet people. Work is stimulating. Direction of the technical side of the company is really good. Genuinely a data driven environment. CEO is awesome and down to earth.
Cons
Really poor WFH policy. I do not think there would be an opportunity to switch to remote work even with a pay cut. Yet some people just do this silently and get away with it. London pay is average comparing to other companies for Data Science. Poor career progression all around and varies massively from team to team. Not much differentiation between people who are very productive and those who aren't. Across all teams it seems like the hardest working people leave and the people who coast along are the ones who stay longest. CEOs pay was disproportionately large in every way.
