4 stages, 1 recruiter call, one competency interview and two technical interviews. All the interviewers were relaxed, asked the questions I would expected for the role. Overall it was a positive experience

The most horrible interview process. Recruiter was ok, and two departments were interested. One department moved faster-ish. Took 2 months to have 3 screens with recruiter, a coding assessment with 3 questions, only one of which is relevant to data science, and a final interview in the form of data process presentation, where you are given two datasets and absolutely no other information -- no scenario, no business question, no guiding problem. It's like they want you to be mind-readers. During the final interview, they acted extremely arrogantly because I did not do what they wanted, which they didn't tell me they wanted in the first place. Never even explained what they wanted to see during or after the interview. I don't think they understand how to do data science and they do not respect you as a candidate. Never heard back from the other department and recruiter quit half-way, so I just got ghosted. Could not have had a worse experience, honestly.
