Me postulé en línea. El proceso tomó 3 meses. Acudí a una entrevista en Two Sigma (New York, NY) en oct 2023
Entrevista
Applied directly on website. About 4 weeks later, was asked to complete an 3 hour online coding challenge. A week or two after that, had phone interviews with a recruiter (non-technical) and then a hiring manager (technical). 3 weeks later, was invited for a virtual onsite consisting of 4 interviews with members of a hiring team. Questions were a standard mix of machine learning, statistics, and probability, both theoretical and applied.
5 weeks after my interviews, I haven't heard a word from the recruiter, despite follow-up emails after 10 and 20 days. Feels like a total waste of time to never hear back after investing ~10 hours inteviewing with this company.

Pregunta 1
Questions about ridge regression, practical/design aspects of supervised learning problems, some transformations of random variables, etc.
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.
