Submitted my resume and got a response about a month later, the interview consisted of basic probability and mental maths questions. The interviewer was very friendly and helped me simplify a few of the questions to make them easier to answer. I am now awaiting for a second round interview in the next week or so.
Questions d'entretien [1]
Question 1
1) 12% of 47
2) If I pick 2 cards from a shuffled deck (with no jokers) what is the probability that they are both a queen?
3) i) If I toss 4 fair coins, I get a dollar for every head, what is the value of this game?
ii) If I have the option to re-toss all 4 coins and must take the value of the second rounds result, what is the value of the game now?
4) How confident are you that you got 0,1,2,3 or all questions correct, giving percentages
5) If two teams play a best 4 of 7 series and have 50% chance of winning each round, what is the probability that they will play to the 7th round?
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.

Entretien
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.
