I applied through a referral. It took a few weeks for the recruiter to get back to me. She scheduled the first round with the hiring manager in Amsterdam. This round was more about my experience and somewhat behavioral. She explained their requirements and challenges very clearly. A few weeks passed before the second technical round was scheduled.
