Before the interviews
When you submit your application to Jane Street for any role, it’s reviewed by an actual human. We respond to every application we receive, ideally within a week or so. Depending on your background we might also suggest you consider another position. We’ll always be up front with you about what roles you’re being considered for (or aren’t), so please also let us know what you’re interested in throughout the process.
If you’ve applied or interviewed before don’t let that stop you from trying again! We reconsider people all the time—people add to their experiences and our needs often change as Jane Street grows—so if it didn’t work out a couple of years ago you might have a better chance this go-around.
Our trading interview process
Our interview process consists of phone interviews at the start, and then in-person interviews for the final stage. The final round interview will consist of a variety of types of questions, which may include problem solving, probability and statistics, coding (in any language of your choice), data analysis, and general interests. All of your interviews will be conducted by quantitative traders asking questions that test a variety of foundational skills that are important for being a successful trader at Jane Street. However, the interview will feel a lot more like a conversation than a quiz and won’t require previous knowledge of finance or involve any complicated math, such as what you might learn in a higher-level math course in college.
Successful candidates are curious, organized, and open-minded. They approach interview questions thoughtfully and collaboratively. Most are comfortable working with numbers and logic. Maybe most importantly, the candidates we ultimately hire are humble, pleasant to work with, and open to feedback. A few other tips:
Approach the problem methodically.
Communicate clearly.
Correct your mistakes.
Ask why.
