I applied in March 2023. There are 5 rounds in total and I got to the last round. The entire process took more than a month. First round is an online assessment where they test numerical, deductive, and inductive reasoning. I had to pass a 90% threshold in the online assessment before getting an introductory call with the recruiter. Then I had a technical interview with the team lead. Passed it too and got a take-home case study and a Python test. Final round consists of 4 interviews (2 technical + 2 behavioral) in total which last for 5 hours.
2-3 hrs OA test, extremely fast-paced, with hard probabilities problems, need to think on the feet. Advised to take some break between the tests, even though it was not listed out.
