Entrevista
It was a phone interview about math stats problems, the interviewer was pretty friendly however the process was kinda stressful. First-round and no behavioral questions asked. I would definitely recommend practicing more before interviewing.

The technical interview consists of "simple" probability/combinatorics questions (by simple I mean that knowledge of advanced statistics isn't needed). The questions can be solved with a high-school level of math but are still difficult.

Phone interview. 2 Probability questions. First one about rolling a dice. You may reroll at certain price. Find the expected pay off. Second one about two players tossing a coin BO7. Say A bets on heads and B bets on tails. Given that the game lasted 7 rounds and first round's a head. What's the probability that B wins?
