I applied online. The process took 3 weeks. I interviewed at StepStone Deutschland (Düsseldorf) in Nov 2021
Interview
First a telephone interview with the Recruiting Manager, then a video interview with the Recruiting Manager and the manager of the team.
Lastly, an interview on-site that lasted more than 2 hours: I was asked to present my business case, then I met the team members and I visited the company.
