Common Interview Questions at Belgian Tech Companies
Walking into a glass-walled office in Brussels or a converted warehouse in Ghent for a tech interview can feel like entering a linguistic and cultural maze. I remember my first technical interview in Antwerp; I was prepared for complex algorithms but was totally blindsided by subtle questions about my "cultural fit" and "modesty." This guide breaks down exactly what Belgian tech recruiters are looking for today.
Understanding the Belgian Tech Culture and Local Expectations
The Belgian tech scene is a unique beast. Unlike the high-octane, "hustle-till-you-drop" culture of Silicon Valley or the aggressive scale-up mentality of London, Belgian companies—even the most cutting-edge ones in Leuven’s biotech corridor or Ghent’s SaaS hub—value consensus, stability, and a certain level of professional humility. If you come in boasting about being a "rockstar" or a "10x developer," you might actually alienate your future teammates.
In my experience, the Belgian interviewer isn't just looking for someone who can write clean code in Rust or manage a Kubernetes cluster. They are looking for someone who won't break the delicate balance of their "flat hierarchy." You’ll find that while the office might look modern, the underlying values are deeply rooted in collaboration. This means your answers shouldn't just be about what you did, but how you enabled the team to succeed. This is a foundational part of Belgian Work Culture: Bilingual Workplaces, Meetings, and Hierarchy that every expat needs to grasp before stepping into the room.
The Nuance of Modesty vs Achievement
In many cultures, the interview is a place to sell yourself aggressively. In Belgium, there is a fine line between confidence and arrogance. When asked about your achievements, the "I" should frequently be replaced with "we." If you built a groundbreaking API, explain the collaborative process. Recruiters here are wary of high-maintenance personalities who might disrupt the workplace harmony.
To bridge the gap between your technical prowess and the local communication style, you might want to look into CVs and Cover Letters in Belgium: Formats and Interview Norms to see how to frame your experience on paper first. If you feel your communication style is too blunt or perhaps too indirect, using platforms like Coursera or Udemy to take a course on "Intercultural Communication" can be a lifesaver. It shows the recruiter that you are self-aware and proactive about integrating into a new European environment.
The Language Equation in Tech
While English is the "lingua franca" of tech in Brussels and Antwerp, don't be fooled. At some point in the interview, the recruiter might ask about your willingness to learn the local language. Even if the job is 100% in English, showing an interest in Dutch or French demonstrates that you aren't just a "mercenary" expat who will leave in six months.
If you are aiming for English-Speaking Jobs in Brussels: EU Bubbles and NGOs, the pressure might be lower, but for local tech firms, saying you are already using DutchPod101 or FrenchPod101 to pick up the basics can give you a massive "social integration" edge. I’ve seen candidates lose out to slightly less technical peers simply because the other person showed a genuine desire to stay in Belgium long-term.
Behavioral Questions You Will Definitely Face
In a Belgian tech interview, the behavioral portion is often as long as the technical one. They want to know who you are after the screen turns off. You are likely to be interviewed not just by a CTO, but also by a peer or a HR manager who will probe your soft skills.
Why Belgium and Why This City
This is the most common "trap" question for expats. The interviewer is trying to gauge your flight risk. They don't want to hire you, spend three months on your onboarding, and then have you move to Berlin because you find Brussels too "grey."
Your answer should be specific. Don't just say "I like the beer." Talk about the central location, the high quality of life, or the specific tech ecosystem in that city. For instance, if you are interviewing in Ghent, mention your interest in the city's history of innovation. If you are still weighing your options, reading up on Where to Live in Belgium: Brussels, Antwerp, Ghent, or Leuven? can help you formulate a more convincing and grounded answer.
Dealing with Conflict in a Flat Hierarchy
Belgium prides itself on a relatively flat organizational structure. You might find yourself in a meeting where a junior developer openly disagrees with the CTO. The interviewer will likely ask: "Tell us about a time you had a technical disagreement with a superior. How did you handle it?"
They are looking for "consensus-building." In Belgium, we don't like shouting matches. We like meetings that lead to a "compromise." Your answer should highlight how you presented data, listened to the other side, and reached a solution that everyone could live with. If you struggle with this, practicing with a tutor on Lingoda can actually help improve your "diplomatic" language skills, even if you are speaking English.
The Question of Work-Life Balance
Belgian companies are increasingly protective of work-life balance, especially with the focus on mental health. You might be asked how you manage your time or how you feel about the "right to disconnect." This isn't a trick to see if you are lazy; it’s a check to see if you’re a burnout risk.
| Interview Topic | What they ask | What they are actually checking |
|---|---|---|
| Relocation | How are you settling into your commune? | Are you struggling with bureaucracy? Will you quit because of stress? |
| Salary | What is your expected monthly net? | Do you understand the Belgian tax system and "fringe benefits"? |
| Teamwork | How do you handle a peer who is underperforming? | Are you empathetic or will you create a toxic environment? |
| Remote Work | How do you stay productive at home? | Can you be trusted without micromanagement? |
Technical Scenarios and Modern Expectations
Of course, it's a tech interview, so your code has to speak for itself. In 2026, the focus has shifted from just "can you code" to "can you code sustainably and ethically."
System Design and Maintenance
A common H3-level deep dive in Belgian interviews involves "legacy" versus "greenfield" projects. Because Belgium has many established firms (banks, insurers, logistics giants), you will often be asked how you would modernize an old system without breaking it.
The question might look like: "If you had to migrate a monolithic Java application to a microservices architecture while maintaining 99.9% uptime for our Antwerp port clients, where would you start?" They want to see a pragmatic, risk-averse approach. They value stability over "moving fast and breaking things."
Artificial Intelligence and Ethical Tech
With the EU AI Act fully in force by 2026, Belgian tech companies are hypersensitive to compliance. You might be asked about the ethical implications of the algorithms you build. "How do you ensure your data sets are unbiased?" or "How do you document your AI models to comply with regional regulations?"
If your background is primarily in non-EU markets, you should spend some time on Coursera or Udemy looking into "EU Data Privacy and AI Ethics." Bringing this up proactively will make you look like a seasoned professional who understands the local legal landscape. This is just as important as knowing Working in Belgium as an Expat: Jobs, Culture, and Hiring (2027) because it shows you are ready to work within the European framework.
The Practical Coding Test
Most Belgian tech firms (like Odoo, Collibra, or Deliverect) use a "take-home" assignment followed by a "technical review" session. They aren't looking for a perfect solution; they are looking for how you respond to feedback. During the review, the lead dev might suggest a different approach just to see if you get defensive. Stay calm, listen, and acknowledge the validity of their suggestion. This is the "Belgian Consensus" in action.
Navigating the "Salary and Benefits" Conversation
This is where many expats trip up. In Belgium, we talk about "Gross vs Net" salary constantly because the tax brackets are so high. If you ask for €6,000 gross thinking you’ll take home €5,000, you are in for a shock.
Understanding the Total Package
When the recruiter asks about your salary expectations, don't just give a number. Ask about the "fringe benefits." In Belgian tech, the "package" often includes a company car (or a mobility budget), a phone plan, a laptop, and the famous Meal Vouchers (Cheques Repas): How This Employee Benefit Works.
I always tell newcomers to use a "net calculator" before the interview. You should also read Gross vs Net Salary in Belgium: Why the Difference is So Big and How to Discuss Salary Expectations During a Belgian Interview to ensure you aren't under-selling yourself or asking for something impossible.
Questions About Your "Status"
If you are a non-EU citizen, the company will ask about your "Single Permit." They need to know if they have to sponsor you or if you already have an "A Card" or an "F Card." Being honest and knowledgeable about your visa status is crucial. If you are unsure about the current 2026 thresholds, check the latest on Single Permit (Gecombineerde Vergunning) Process for Workers to show them you’ve done your homework and won't be an administrative burden for their HR department.
The Indexation Talk
Inflation is still a topic of conversation. You should understand the Indexation of Salaries in Belgium: How Inflation Adjustments Work. In a tech interview, you might ask: "When does your company typically apply the sectoral indexation?" This shows you are a "local" expert who understands how the Belgian economy protects worker's purchasing power. It’s a very "insider" question that will impress seasoned HR managers.
Final Advice for the Big Day
Before you head out, make sure you’ve checked the commute. If you are interviewing in Brussels, the STIB/MIVB can be unpredictable. Being "Belgian late" (5 minutes early) is the gold standard. Dress code in tech is usually "clean casual"—jeans and a nice shirt/sweater are fine, but maybe leave the hoodie at home for the first meeting unless it's a very small startup.
Don't forget to ask them questions too. Ask about their "joint committee" (likely CP 200 for tech), ask about their remote work policy, and ask how the team celebrates successes. Showing interest in the social fabric of the company is the best way to prove you’re ready to call Belgium your new professional home.
