J'ai postulé via un recruteur. Le processus a pris 1 jour. J'ai passé un entretien chez Two Sigma en oct. 2010
Entretien
I got a phone interview from two sigma last friday and got the code test today. The code test is not difficult but the two hour time limit is really a big problem. The code test consists of two problems. The first one is very easy, which is about missing characters. The second one really took me a long time. It is about the animation of particles moving around. I took another 40 min to figure it out.
Questions d'entretien [1]
Question 1
There are a collection of particles. You are given a string of 'L' and 'R's, where 'L' denote a left moving particle and 'R' denote a right moving particle. The moving speed is given as another parameter. Multiple particles could stay on the same position. Give the animation of the moving particles.
I interviewed on zoom with three different interviewers. The first was talking to a recruiter about interview processes and why I am applying and going over my resume. The second was with a quant researcher about my resume, past research and domain knowledge and technical questions. The third round was with another quant researcher about past research and some more technical questions. I didn't proceed after that.

Question 1
statistics and regression questions and some math brainteasers
The interview process typically starts with conversations with team members, followed by three rounds of technical interviews focused on data analysis, coding, and statistics. Each round includes follow-up questions that probe deeper into the candidate’s reasoning, methodology, and ability to apply concepts under realistic problem-solving scenarios.

Interview mostly consisted of conceptual ML questions and general experience, with no coding. The interviewer was super nice, but they were looking for more experienced candidates, which my years of experience didn’t quite qualify me for.
