Curious? Let’s Talk.
We believe that good collaboration starts with genuine dialogue.
That’s why we’ve designed our selection process so both sides can find out whether it’s the right fit – professionally and personally.
We usually get back to you within a few days.
Our process consists of three interviews – fair, transparent, and on equal footing. At least one is via video, two are usually in person.
This way, you’ll get to know not only us but also how we work on site.
Our process consists of three clearly structured interviews:
Initial Introduction (remote, approx. 30 minutes)
You’ll speak with our recruiting team. We’ll clarify initial questions, discuss expectations, and check whether our values and way of working align with your profile.
Technical Interview with Your Potential Manager
Here we go deeper. We want to understand how you work, what experience you bring, and how you tackle challenges. You’ll also gain insight into how we lead, make decisions, and collaborate.
Personal Meeting with the Team – Ideally On Site
You’ll meet colleagues you may work with in the future. It’s important to us that you get your own impression of our work environment, culture, and processes.
We conduct all interviews as equals – open, honest, and respectful.
You’ll have the space you need to ask questions and make a well-informed decision – just as we do.
