Want to know more?

  • How does Coolblue adhere to the 1.5-meter rule at work?

    We adhere to the recommendations and guidelines of RIVM and the government, of course. This means that all colleagues from the main office work from home as much as possible. The interviews for your application will also take place via video calls.

    We’d be happy to have you at the office on your first day. So we can drink a cup of coffee and get to know each other a little better. At an appropriate distance, of course.

  • Can I keep developing myself?

    Coolblue University: learning at Coolblue, in a different way.

    With over 30 training courses in our own Coolblue University, you can get a little bit better every day. At Coolblue, we go back to school sometimes. But not by sitting there quietly and just listening. The training courses aren't boring, but interactive. You have to do exercises and have discussions with others. At the Coolblue University, we choose what we want to learn, so we can continue to develop en become real experts. For example, a Delivery Driver needs different training courses than a Customer Service Employe and a starter needs different courses than a manager.
