It was not that bad, 3 initial rounds overall okay, it would have been nice if they added some more depth in questions and asked good questions. and it would have been great if they call or tell something before interview.

terrible Data Scientist role interview process, took 3 months and got rejected after final interview where the interviewer didn't have my resume and asked something else which the recruiter did not mention to prepare

A recruiter phone call and then a coding round. SQL medium + predictive modeling. I think the modeling task could be a take-home assignment. However, the test was closed before the promised time. It was a 89-minute test.
