Central limit theorem problem and programming problem. Standard stuff. Programming was leetcode easy/mediim. Interviewer mainly talked about my background tbh, I finished the problems in 5 mins. Also, the interviewer had a very thick accent.

Online assessment and coding for a first round with básicamente questions. Then one ronda of interviews with basuc maths quick questions and some dev pricing. The final ronda was 4 interviews of 1h each.
