Process involves 3 x 1 hour virtual interviews that will cover basic probability/stats/coding tasks, passing this there is an in person day with a more involved challenge and presentation to team. Final HR style interview will only happen all this and one should expect 2-3 weeks between interviews.

I went through 2 rounds. Both rounds asked a lot of tech questions such as linear regression, mean-variance optimization, and traditional quant questions(probability, etc.). Overall not too hard, received reject letter in a week.
