Our guide is marked **Verified** and is created from recent, real, first-hand insights shared by interviewers and candidates. If your experience differs, [tell us here](https://www.aced.io/questions/contribute). Jane Street's software engineer interview is described as collaborative, despite its public reputation for brain-teasers and mental math. Much of the loop develops one coding challenge as interviewers add requirements. Interviewers evaluate how cleanly candidates build and explain their work, as well as how they communicate throughout each round. ## Jane Street software engineer interview process The process has two main parts: a remote technical screen and a full-day onsite. Senior candidates also have a project discussion during the onsite day. Rather than presenting a new question in every round, Jane Street often develops one coding solution as interviewers layer on requirements. The process can include: - **Recruiter conversation:** A brief call that sets expectations and explains the collaborative, hints-allowed format. - **Technical screen:** A roughly 60-minute remote coding round with one interviewer, using a single challenge in the candidate's strongest language. - **Onsite coding rounds:** A full day of three to four long coding rounds, usually around 70 minutes each; most have two interviewers. - **Project discussion (senior and up):** A conversational discussion about a past technical project, focused on the reasoning behind the candidate's decisions. The exact number of onsite rounds varies by candidate, level, team, and office. Candidates should expect their own loop to vary. ## Recruiter conversation The recruiter call lasts approximately **20–30 minutes** and sets expectations before the technical rounds. Topics include the candidate's background, reasons for wanting to join Jane Street, and logistics such as location and timing. The rest of this guide is available to members.
