The interviewer seemed surprised I hadn't prepped distributed systems more lol. Hacker rank was 2 questions. SQL assessment had Snowflake specific syntax for streaming data, more complex than expected. Superday had 4 sessions but couldn't answer the system design on distributed query optimization well enough
