Two interviews, first assessment center, classic procedure: two case studies to solve in team and an interview vis a vis with the hr. Second interview with the head of operations, he asked me only motivational questions and about my experience and ideas. He always wanted me to explain the reasons behind. Did not get the job because I was not confident enough in the answers.

Easy, one interview with them, they are actively looking for people since they have a big churn rate, then it is not that hard to land a job there. They ask you about your past experiences, skills, then they want to know more about your constraints to start if you pass the bare minimum.
