Pros

No micromanaging, good pay, good benefits for london based employees

Cons

unrealistic product milestones and extreme ambiguity on asks, unfair OKRs, no ability to calibrate on feedback in time as it is not given timely, peers give only positive feedback so there is not way to understand negative yearly review

Pros

The culture at Flagstone is a genuine strength. There is a real sense that people are listened to and that their wellbeing matters. It feels like being part of something meaningful — a company at an exciting stage of growth, large enough to offer real opportunity but still small enough that individuals are known, valued, and recognised for their contribution.

Cons

At this stage, there are no significant areas for development to highlight.
