Application process

Initial HR call

Once you apply, our hiring journey begins. The HR team carefully reviews your profile to see if there's a potential match. If so, we'll invite you for a first conversation, either over the phone, via Microsoft Teams, or at our headquarters in Gentbrugge. This informal chat helps us understand your motivations and gives you a chance to ask questions.

Interview with the hiring manager

Still a good fit? Then we'll invite you for an in-depth interview with the team lead or department manager. Depending on the role, we may include a short practical test to get a clearer picture of your skills, nothing to stress about, just an opportunity to show us what you can do.

Offer & proposal

If everything lines up, you'll receive a contract proposal from us. You'll have the time to review the offer and think things through. If you accept, we'll schedule a contract discussion and get everything ready for your onboarding.

Off to a flying start!

Welcome to the team! Before your first day, we'll prepare your onboarding plan and make sure everything's in place. On arrival, your HR contact and a dedicated mentor will guide you through your first weeks, with training and support tailored to your role. After six weeks, we'll check in to see how things are going.
