It starts with a written Slack interview (which took me a day to write excellently), then a take-home assignment that took me 3-4 days, including analytics+ML model+design+productionizing. Then an interview that includes questions on take-home and some ML based questions. Then comes a presentation round where you present a project which took me a day to prepare. Honestly, it took me a total of more than 6-7 days fulltime to prepare for the process - only to be rejected with a generic email. Everyone i met were nice but very poor communication. One of the worst after-decision experiences.
