Candidatei-me online. O processo levou 4 semanas. Fui entrevistado pela Two Sigma em nov. de 2018
Entrevista
It was a code test and HR phone interview, followed by a technical phone interview. I didn't pass the technical phone interview, although it was easy and I was asked about the exact same question I saw on glassdoor. I thought I got the answer, but actually I didn't.

What is the relation between regress Y on X and regress X on Y? Be prepared to derive the relation between 2 r-squares analytically.
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.

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.

Fiz uma entrevista na empresa Two Sigma (New York, NY).

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.
