Candidatei-me online. O processo levou 2 meses. Fui entrevistado pela Two Sigma (New York, NY) em mai. de 2018
Entrevista
I did a coding test followed by an onsite interview. For the onsite interview, when you go for lunch they decide whether to continue the process. I was brought back for additional interviews, but never got an offer. The junior people were generally pretty friendly, but the senior people that I met were not.

Pergunta 1
Standard ball probability questions, basic coding, a calculus question, some basic linear algebra, some ML, a data question about identifying data that is uncorrelated but not independent.
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.

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