Sectors
What roles and sectors does Arcadius focus on?
Arcadius focuses exclusively on administrative and support roles within the business services sector in Belgium. They specialize in placing candidates who possess high-level trilingual capabilities, typically Dutch, French, and English. Their placements range from executive assistants and office managers to specialized administrative support staff who operate in complex, multilingual corporate environments.
Where you meet
How does the staffing process work for a candidate?
The process begins with a screening of your language skills and administrative experience to determine your suitability for current vacancies. If you are a match, a consultant will interview you to understand your career goals and professional background. Once vetted, Arcadius presents your profile to their corporate clients, manages the interview scheduling, and facilitates feedback throughout the hiring process.
What should I expect once I engage with the agency?
Expect a professional, candidate-focused relationship where communication is centered on specific job opportunities that match your trilingual profile. Arcadius consultants act as your advocates, meaning they will guide you on how to present your experience to their clients. There is no cost to you as a candidate, as the agency fee is paid entirely by the hiring company.
Your side
How can I get on the Arcadius radar?
To stand out, ensure your CV explicitly highlights your language proficiency levels for each language you speak. Use keywords related to office management, project support, and specific software tools common in business services. Registering directly on their platform and keeping your profile updated with your current availability is the most effective way to ensure recruiters find you when a relevant role opens.
Is Arcadius the right fit for my job search?
Arcadius is an excellent partner if you are a trilingual administrative professional seeking a role in the Belgian business services sector. If your profile does not include strong multilingual skills or if you are seeking roles outside of administrative support, you may find better success with agencies specializing in other domains. They are best suited for candidates who want a specialized partner to navigate the specific demands of the Belgian corporate market.

Frequently asked questions
Should I register with multiple agencies while working with Arcadius?
Yes, it is common practice in the Belgian market to register with multiple agencies to maximize your exposure to different job markets. However, always be transparent with your Arcadius consultant if you have applied to a role elsewhere to avoid duplicate submissions to the same employer.
What happens to my personal data after I submit my CV?
Arcadius stores your data in their internal database to match you with future vacancies that align with your skills. They are required to comply with GDPR regulations, meaning they must obtain your explicit consent before presenting your profile to any potential employer.
Should I apply directly to companies if I am already represented by Arcadius?
It is generally advised to coordinate this with your consultant. If Arcadius has already submitted your profile to a specific company, applying independently can create confusion and potentially disqualify you from the process due to agency terms of business.
How should I follow up if I have not heard back after an interview?
If you have not received an update within the timeframe discussed, send a polite, concise email to your consultant. This shows professional interest and allows the consultant to provide you with the latest status update from the client.
