Bad Process, had a couple good interviews, then had an interview with the CEO which was weird, and he was asking weird questions, almost suggesting that I am lying about my work. Got ghosted for 2 weeks after, only to get rejected after following up.

HR reachout -> online assessment (ML/DSA) -> technical Q1 (1 - 2 LC medium/hard) -> onsite superday. Didn't make it to the final round. Overall experience was good but no question about data science or machine learning was asked.
