Solicité el puesto a través de la escuela superior o la universidad. El proceso duró 2 semanas. Acudí a una entrevista en Two Sigma (New York, NY) en oct 2012
Entrevista
First round with HR. Very friendly, asked fit questions. What is ideal role, what is my experience with coding etc. Asked about previous employments. Then coding test. Needs to be in C++, C, or Java. I haven't used any of these languages for a long time, so was very rusty and couldn't finish the test in time. Quickly after they said they are not interested in me anymore. The coding test is fairly easy if you are familiar with the syntax of the coding language. So pseudo code is really not a problem. Questions have been listed in this forum: Sort a list of words and integers and keep the relative order of words and integers, plus your data-center screwed up and know every data center needs to have the data from the other centers again, what is the most efficient way to copy data such that every center has it.

No difficult questions in the coding test, as long as you are familiar with the syntax. It might help if you have a set of predefined functions available (e.g., sorting algorithm), I didn't have that and had to code up everything from scratch in the two hours time limit.
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.

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.
