2 phone calls, 1 in person round. All interviewers were nice. Office was really nice. Interviewers were 1 hour each and consisted of standard quant questions. One interview had a coding element to it.

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.
