Our Recruitment Ethos

We’re united by a deep intellectual curiosity and desire to use our abilities for measurable positive impact.

A note on AI: we're happy for you to use it for research and interview prep, but please don't use it to generate answers during live interviews. We also use an AI note-taker (Metaview) in interviews so interviewers can stay present (which you can opt out of just let us know,) and every application is reviewed by a human, never decided by AI.
