The process was fast and efficient. I applied online for an internship and the whole process took about 2 months for 3 interviews, although it might extend up to 5 interviews depending on the candidate. All the interviews were by phone call and the interviewers were really nice.

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.
