What will happen next

Once we receive your application, it will be thoroughly reviewed by a team consisting of the responsible HR representative and the hiring managers to assess how well it fits our requirements.
If your application results in a positive evaluation, we will invite you to a first video interview as the next step. Followed by another Meetup in person, in our Düsseldorf Office or via Teams.
