Me postulé en línea. El proceso tomó 2 semanas. Acudí a una entrevista en Two Sigma (Londres, Inglaterra) en oct 2017
Entrevista
Applied through their website. Got an email the next day offering a HackerRank test. Then phone call with a recruiter, and on-sites scheduled the next week. On-sites lasted from 9am to 6pm, with a succession of 1 hour rounds, and a lunch with part of the team in the middle.
The questions were interesting and challenging, everybody was nice and smart – interviewers were helpful and it felt like they wanted me to succeed. The whole experience was very pleasant. Got a phone call from the recruiter congratulating me and telling me they would extend an offer. Offer came a week later.

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.
