I applied through college or university. The process took 1 day. I interviewed at Jane Street (New York, NY) in Jan 2011
Interview
All financial firm interviewers that came to our university are well-dressed professionals from Bulge Bracket firm names (Morgan Stanley, Goldman Sacchs, ...) to small boutique firms (Lazard, ...) EXCEPT for the Jane Street guys. I was interviewed by a nerdy looking person in a t-shirt and jeans (I have nothing against nerdy looking people. This is purely an observation). The guy either had little social skills in comparisons to interviewers from other firms, or was deeply uninterested in getting to know people and their resumes. He literally spent 3 minutes talking about my resume, and 25 minutes asking me math and probabilty questions, which was strange, but I guess fair too given the position that I was applying to. When he asked me what my favorite course was, I replied "Financial Institutions. It's a course where I got to learn about various financial institutions ranging all the way from commercial banks and insurance agencies to hedge funds, investment banks, and private equity firms". The interviewer then replied "Oh that sounds really cool. I know very little, if any, about these things, haha". I laughed along, but I would lie if I said that I wasn't put off by his comment. The interview then started with 25minutes of math and probablity.
Interview questions [1]
Question 1
You have 2 decks of cards (each deck contains both red and black cards). One deck has twice the number of cards in the other deck with the same color ration (so one deck has 52 cards and the other has 104, both half red and half black). I offer you to play a game. First you get to chose which deck of cards you want to play with. Second, you draw 2 cards at random from your deck of choice. If both are red, then I will give you a ferarri. Which deck of cards would you chose?
Some brain teasers and probability problems that are variations of commonly seen quant interview problems. Require smart reacting rather than very high level maths or finance knowledge. Friendly interviewers, active involvement.
The interview process involved multiple rounds, starting with a phone screen covering probability, brain teasers, and market-related questions. This was followed by a technical assessment focused on programming and mathematical problem-solving. The final round included onsite interviews with case studies, logic puzzles, and discussions on trading strategies. The process emphasized clear thinking, structured problem-solving, and strong quantitative skills.

Zoom interview, The audio quality is very poor, and I find it very difficult to hear the interviewer's speech clearly. They asked a question about probability. Zoom interview, The audio quality is very poor
