J'ai postulé via un recruteur. Le processus a pris 1 jour. J'ai passé un entretien chez Two Sigma en nov. 2010
Entretien
Got a phone interview + code test first. Code test is average. Got response one week later saying i am invited to a full day on-site interview. The interview starts from 9am and i was interviewed by 3 people in the morning. I was able to answer most of their questions and solved the rest after given a few tips. The questions cover basic maths, algorithms/data-structures (hash-table/BST) as well as coding on a computer. They bought me a to a restaurant in the noon and I had a free lunch. However, the first guy in the afternoon was late by 15 mins. He asked me a probability problem upfront. I got stuck unfortunately and was unable to solve it until he gave me many tips. This used up my time. After he left for a couple minutes HR came and told me I was done today. I was quite unhappy and felt insulted. Being rejected immediately because I did not do well in a single interview is unreasonable.

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.
