first round is a coding quiz and after you pass the first one, there is one behavior survey that will not affect your application, then the last round is director interview.
Video interview, basically walking through the tech stack(e.g. Hadoop, Hive, Flink, Kafka) and previous data warehousing projects(details and relevent troubleshooting process) on CV. Some ad-hoc questions(e.g. how to deal with data skew in mapreduce task) were also asked.
