Me postulé a través de una recomendación de un empleado. El proceso tomó 4 semanas. Acudí a una entrevista en Two Sigma (New York, NY) en jun 2016
Entrevista
1 HR call, 1 online test, 1 phone screen and 1 on-site. For the on-site there were 3 rounds in the morning, and then lunch with 2 employees, which were explicitly said to be not part of the interview process. I did not make it to the afternoon rounds. The interview itself was conducted professionally, but the HR coordination is a mess. I had to interact with 4 different HR people in the process and it was no surprise that something went wrong. On the day of the on-site I was instructed to go to the wrong building in the morning. The interviewers were given a very out of date version of my resume, which created a lot confusions (BTW I sent them my latest resume early in the process). I got the impression that they interviewed a lot of people and either didn't have the resource or didn't bother to make process smoother for the candidates.

Standard medium difficulty hackerrank. The question involved decoded an encoded string. It was not something I had seen on LeetCode before and I think was unique to the company. The question was not that difficult but I ran out of time right before I could finish answering.
