Tableau Software Lead Engineer interview questions

Applied through LinkedIn, the recruiter scheduled the first round in hakerrank coding challenge, then virtual onsite interview. Virtual onside was 5hours, first two rounds are coding, 2 questions each, one round desgin, its about data governance desgin, one round by director for an hour, one round by hiring manager he asked some coding and design. The Director round is a bit unusual for an hour!! No direction in the discussion. The desing round also very vague!
