I really enjoy your short tips and like the idea of bringing in developers to the table.

David, recruiter

Just signed up! There is always plenty to learn in this challenging and dynamic market!

Marta, recruiter

I was really surprised how professional the course from Geekruiter is - IT people finally speak a normal language that everyone can understand! It is very much visible how much work they have invested in order to help recruiters understand technical fundamentals; so essential for our work!

I got to learn a lot of new things, made things clear that I thought I knew, but Michal together with his team helped me to understand it in a wider concept.

I do recommend you to join Geekruiter - learning is fun with them and they are ready to explain you every single detail that you were afraid to ask before.
