Hiring Journey
Our recruitment process is designed to give you a real sense of our identity. You’ll meet our people, experience our culture, and connect with department heads so you can make a well-informed decision, with no surprises once you join.

1. Application & Initial Review
Submit your CV and cover letter through our careers page. Our HRM team reviews your profile, and you’ll always get a response: yes or no, so you can move forward with clarity.
2. Introductory Meeting
If there’s a potential match, we’ll invite you for a 45-minute conversation with HR at our Rotterdam office. It’s about getting to know each other, aligning expectations, and giving you a feel for our culture.
We will arrange the interview online if you're not based in the Netherlands.
3. Technical / Role-Specific Assignment
Spend a day working on a practical assignment, guided by one of our team members. You’ll get a real taste of the role and how we collaborate.
4. Team Technical Fit Interview
Meet our Heads of Development in an online interview. Together, we’ll explore your skills and working style to find the best fit within our teams.
5. Meeting with Our Managing Partner
Have an informal talk with our Managing Partner/CEO to connect on vision, values, and leadership.
6. Offer & Onboarding
We’ll share a personalised offer and walk you through salary, benefits, and your growth path. From day one, you’ll know exactly where you stand and how we’ll support your development.

FAQs
Our recruitment process typically takes about 3 weeks, but we understand that life is busy, especially when arranging a full-day assignment with us. We ask candidates to spend one whole day with our team, which may take some planning on your side. That’s completely okay.
We respect your time and are happy to schedule things in advance or move at a pace that fits your agenda. The timeline is flexible and largely depends on your availability. Whether you want to move fast or take it step by step, we’ll support your pace.
No need for formal prep, we’re not here to catch you off guard. Your skills will shine through during the practical assignment.
For the rest, it’s simply about being yourself. We focus on open conversations, your attitude, communication style, and how you approach collaboration and learning. We’re more interested in who you are and how you think than in perfect answers.
No. Our working language is English, and many of our team members come from international backgrounds. Dutch is not a requirement.
Yes, for the right candidates, we offer visa sponsorship and support relocation to the Netherlands. This is evaluated on a case-by-case basis.
We make commuting as stress-free as possible. Instead of a company car, we provide a first-class train pass with access to all public transport across the Netherlands. It’s an eco-friendly, comfortable way to travel and ensures you can get to the office, client sites, or anywhere else you need with ease.
Casual, but appropriate. We care more about what you bring to the table than what you wear to it.
That said, we expect a level of professionalism in how you present yourself, especially when meeting clients or joining team sessions.
