Imagine this: you come across a vacancy that’s a perfect fit for you. You’re excited, you have the right skills, but… you don’t get invited for an interview. Why?
Your CV only shows your work experience—it doesn’t reflect that you’re results-driven, have strong problem-solving skills, or the ability to quickly learn new things, all of which are crucial for the role.

Frustrating, right?

Welcome to Assessio

Organizations save time in the recruitment process, improve the quality of their hires, and increase long-term employee engagement.

We do this for more than 2,000 organizations, including Rabobank, G-Star, KLM, Maandag, and PostNL.

Our hiring process

We practice what we preach. That’s why we ask you to complete two assessments: a personality test  a cognitive ability test and sometimes a motivation test. Everyone does this. Why? Because we want to give everyone a fair chance and base our decisions on data—not gut feeling. It takes about 50 minutes, and once completed, you’ll receive a quick response from us.
