Candidatei-me por meio de recrutador(a). O processo levou 2 semanas. Fui entrevistado pela Two Sigma em set. de 2016
Entrevista
The process was brief, there was a 3 hour online coding question, followed by an HR round. During the HR round we discovered that visa sponsorship would be an issue, and that they would not be able to continue the process. It might be worthwhile to check this beforehand, although I don't think of the coding test as time wasted; it was a confidence boost and I learned some valuable techniques during the preparation.

It will be a phone interview first. They will ask you technical questions about probability/ statistics. The interviewer is friendly, but the question is not easy. The process is good.
