Online assessment over spark and basic programming questions, very fundamental ones, someone straight out of high school might be able to do these. Followed by a single HR round, which only focused on the top-5 HR questions you can google, why data, why analyst, past experience and where do you see yourself in 5years. Simple 30min interview, after which I was offered the role by another HR, I was a bit skeptical as none of these guys could be found on linkedin.... HR was persuasive to buy a course on "apache spark" from an agency which costs 20,000 INR and said the company would re-imburse this along with my first paycheck. HR didn't follow up, I chose to join another company as none of it felt secure, people mentioned in the offer letter could not be found online.
