Entrevista
I first had a phone interview where I was asked about my background. Then there were some conceptual Python questions and SQL questions. Everyone was very friendly throughout the whole process and the interview was much easier than I expected. There was no whiteboard coding since the interview was focused more on knowledge of Python data structures and discussion of database technologies.
