Candidatei-me online. O processo levou 1 semana. Fui entrevistado pela Jane Street em dez. de 2014
Entrevista
I applied online and got a reply the next day asking me to schedule an interview. I scheduled it for the week after and the called me at the exact time we agreed upon. The interviewer asked me about my ongoing Math Ph.D. research and even though he didn't understand much of my field, he asked me to be specific about what I was talking about. Following this, he asked me two math puzzles that looked easy but ended up begin a bit more challenging than expected. I had to be pointed in the right direction before successfully answering the questions.

Pergunta 1
There is a solar system with three planets orbiting around the sun. One of them has a translation period of 60 years, another one of 84 years and another one of 140 years. Today, the three planets are aligned with the sun. When is the next time the three planets will be aligned with the sun?
The process began with serveral online tests for maths and logic. They gave a personal interview to get to know the candidate better and evaluate fit for the company/role, then held a technical interview covering maths and logic problems.

Entrevista
Fun and filled with unexpected questions. The questions rely on fast thinking and fast calculations, and sometimes intuition because there is no sufficient time for me to work through the whole problem.
We started with a bit of small talk, followed by some probability questions. Ended with some basic algebra questions, Make sure to ask questions if you have any. Good experience, feels like the interviewer was trading.
