J'ai postulé en ligne. Le processus a pris plus d'une semaine. J'ai passé un entretien chez Quantcast (Londres, Angleterre) en févr. 2016
Entretien
Very efficient and pleasant process. I submitted my CV, got a response from HR the next day. A phone interview one week later. Phone interview was technical with questions of intermediate difficulty. I failed 1-2 of the technical questions and did not proceed to the next stage. Despite this negative outcome, I was impressed by the efficient interview process.

Entretien
I was contacted by a recruiter. I then had two phone screens. The phone screens were friendly and very focused on machine learning. The folks there have interesting backgrounds and asked very pointed questions. Ultimately, I didn't get an offer though the experience was ok.
Overall I got the impression that their work was interesting and that they have strong momentum in their problem space.

Entretien
The hiring process consisted of two phone interviews (technical) followed by an on-site follow up. The interview had a strong focus on probability and statistics; mainly on how to model problems, and evaluate the assumptions made in order to get a tractable solution. I found the interviews challenging but came away with a good feeling. The interviewers were engaging and dropped hints when they found me struggling. Most of the interview questions are based on actual scenarios encountered at Quantcast.
