Tableau Software Senior Software Engineer interview questions

Recruiting agency got in touch with me regarding a tableau hiring drive .I was immediately given a hackerrank coding challenge.. Medium level .I was invited for the virtual onsite ,Did not have time to prepare. had to schedule on the same date they provided .First round was with engineer .It was coding round -Dynamic programing , next round was with another engineer , coding again , easy .Hiring manager as about behavioral questions , finally one round with Team lead system design. this person was so unprepared and did not know what to ask. Was constantly looking at the time to finish of the interview..

3 Rounds ..Phone call + 5 onsite interviews + 1 take home assessment post onsite to determine level + compensation leetcode medium/hard questions ..Just practice those and be honest about your experience.
