Why work with us?

Recruit4.Work was built on four core values, and they are as relevant today as the day we began: honesty and clarity, proactivity, long-term relationships, and knowledge.

  • Honesty and clarity

    We ensure these values are the basis of our interaction with everyone; clients, candidates, suppliers and each other.

  • Proactivity

    We are creative and solutions driven and don’t rely on existing methods. We are flexible, open to change and constantly question the status quo

  • Long-term relationships

    We develop relationships with a view to forming successful and sustainable long term partnerships of mutual benefit.

  • Knowledge

    We continually build upon our in-depth understanding of the disciplines and sectors in which we operate.


Recruit4.work will do more than just finding that absolute professional for you. We judge the person also at their personal and contactual abilities.

Will he/she fit within your organisation structure? Is he/she a real team player, will he/she show enough leadership to lead a larger unit, is it a real personality, and will he/she estimate that very special procedures characterizing your organisation?

A company specialized in recruitment and selection will take those aspects seriously in the profile. 

Recruit4.work is such a company.
