Entrevista
The interview process was too long, consisting of about ten interviews during many weeks, and including a quite complex coding test. I had interviews with many different interviewers, or even the same interviewer wearing different hats in different times.

Pregunta 1
Challenges in previous projects. Coding exercise: optimize a Spark query, comment a series of python scripts, solve a series of SQL puzzle, implement a machine learning solution with Spark.
The interview questions includes from ML concepts to python design, which is harder than I expected. But can use SQL as well. You can choose what you want to use.
3 rounds, 1 case interview, 1 fundamentals and 1 SQL interview. The case interview was extremely technical and the fundamentals interview didn't cover my resume at all. Overall it was quite difficult, and the fundamentals interview prep sheet was not helpful at all
