Start with Screening with a recruiter, followed by 4 rounds. R1: SQL + Python questions (Easy/Medium) + DS/ML theory R2: Mini case (Risk) + SQL + Python questions (Easy/Medium) R3: Mini case (Risk) + Past Experience based R4: Business Strategy (Risk) + Past Experience based

Had 3-4 rounds of interview which went well. Last round was more of a discussion and I was very hopeful of an offer but in the end they never came back.
