Jane Street Interview Questions

Interview

I applied for a trader position off my college’s career site. They were prompt in replying. I received two phone interviews. The first was easy probability questions, but the second had more difficult questions. I did not get a final round interview. The younger guy I interviewed with was friendly but the older guy was really harsh/dismissive when I got something wrong.

Application

I applied through college or university. The process took 2 weeks. I interviewed at Jane Street in January 2014.

Interview

Contact was made by e-mail to setup a phone interview. Interview was extremely quantitative, but relatively obscure. Main question was about a complex probability game that the interviewer expected you to calculate mentally. A few more obscure technical questions (as a person coming from a math background) and the interview was over. Process seemed self-defeating as a very small number of people would have the intuition to quickly do a problem like that in their head, but that says little about skill.

Interview

the interview is intro college probability questions, each two or more parts. you have plenty of time and you can explain your rationale before or after solving the problem, but it should be coherent. it's very relaxed.

Interview

First round is a phone interview. A trader at the firm will ask four or five brain-teaser questions. Interview took about an hour. The trader was very kind and patient and gave suggestions when I was stuck on a question. It seemed that the interviewer was testing how I responded to not immediately knowing the answer or the process.

After submitting an application on my University website, I was contacted a few weeks later to set up a coding interview by phone. The interview focused on linked list implementation, optimization and optimal algorithms for searching, inserting, etc. All employees I interacted with in the process were very kind and knowledgable, seems like a great company!

Interview

I had two interviews. Someone emailed me, set up and interview over email, and then I got a call at the agreed time, a few days later. The first one was with someone who seemed very enthusiastic and knowledgeable, who asked deep challenging questions. The second person asked straightforward algos questions and didn't understand the algorithm I was trying to describe to him over the phone.
