The people were very friendly and the process was clear. - 1st round: 30 min phone call with basic motivation questions (why Coolblue etc.), salary expectations (they said somewhere at the lower end of 3100 to 3600), and very basic data science questions - 2nd round: 1h virtual interview, talking about a data science project of yours (20-30 mins) and some behavioural questions (mostly how you work in teams) - 3rd round: 7 day take-home forecasting assignment and a report. They said it would take 1 day of work, but it took at least 4 days for me. It is also vague: there is a large emphasis on making it efficient, but there is no objective measurement for this. Explain everything - 4th round: 30 min virtual interview about assignment and 2x 45 min virtual interview with data scientists perhaps about technical and behavioural questions

First step was to call with the HR person. Then had an interview with the team lead and a data scientist which I talked about one of my projects. After that they gave a case to do at home and send the answers. I failed at that step so I don't know what comes next.
