Jump is quite streamlined with only two main rounds: 1-hour online interview then superday. a few HR calls in between.
Superday is very technical. They cater to the content that you're supposed to know given your background, so it's fair.
Questions d'entretien [1]
Question 1
Statistics, linear algebra, some challenging brain teasers

Few Hr calls prior and between.
First round: Probability questions, questions on general ml knowledge: lasso, ridge, mathematical justification of gradient descent, prob inequalities, linear algebra and geometric interpretations of probability. Final Onsite: Leetcode problems, stats, harder probability problems, deeper into ml knowledge: linear regression basics, pca, linear algebra, questions on the classes you have taken.
ML knowledge is very much needed.

interviewed with low-mid frequency equity team.
1st round: coding + statistics, mainly probability, stochastics and OLS. Questions are quite interesting.
2nd round: only about past experience, focus on all the details.
3rd round: onsite interview.
Well organized process: first round covered resume walkthrough, probability, and combinatorics. Final round included deeper probability questions, a data interview, and an HR discussion. Overall, a structured and positive experience.
