1)Phone interview 2)Assigment 3)Aptitude test They put me in the process of doing the assigment which took me 5 days to complete it and then rejected me by saying that at the aptitude test I answered 13/20 correct questions while I had to make 15/20. --During the process they showed non-professional behavior.

First round was a basic get to know you phone call, second round was a coding challenge with 3 problems. The second round included processing a log file, using PostgreSQL, and using an API.
