Entrevista
Nice and friendly interaction throughout, interview was technical in the sense it tests your mathematical ability to quick thinking on the spot and how you solve problems logically. Not many questions but you go rather in depth for each of your answers
They tend to examine the logical thinkers that can communicate clearly and concisely, and some problem-solving exercises intended to explore how you gather and apply new information, very different from other tech companies' interviews.
Initial application and online assessment. Had a first round behavioral interview where they asked me about myself, my experiences, and a couple of brain teasers. The interviewer was very nice.

Entrevista
Phone interviews (at least 3) - questions were of mixed difficulty (some pretty hard) but the interviewers were friendly and they gave helpful hints. Kind of fun - review probability and game-type questions.
