Extremely negative experience. Interviewer spoke broken English and had a difficult time explaining coding questions. Provided no guidance and in hindsight directly misled me. Very unfriendly and rejection email was quite unpleasant.

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.
