Jane Street Software Engineer Interview

Hi everyone, I recently applied to Jane Street for their Software Engineering role and have been asked to participate in the first round of interviews. The interview process when joining AWS comprised a fairly equal mix between technical and behavioural questions - I’m wondering how this is different at Jane Street? Is it purely technical? Additionally, has anyone found good resources for interviewing there? From the brief research I’ve done it seems like they ask open-ended questions and place a large emphasis on clean/concise code. Thank you! #interview #finance
