Multiple steps:
1. Online test, mostly mathematical, logical and methodical questions (sorting and calculating percentages, scheduling meetings in a team, etc.)
2. First interview (30 min), more general questions, CV is talked about, previous experiences, etc., Brain teaser and a percentage has to be calculated out loud (some % of 440)
3. Recruiting Friday (Introduction presentation followed by 3 interviews (around 1 hour each) back to back, with people from different teams.
CV was asked about in every interview, but the focus is on more behavioral and situational questions (what would you do if...)
Brain teaser (what would you do with scissors as a delivery boy) and percentages were asked again, some further creative questions, too
Also a case study about a sleep beer (decide if investment is worth it)
