We do not like complicated recruitment processes, so we have developed a few simple steps that will allow us to get to know each other better. We start with a telephone conversation during which we will discuss your current professional situation, competencies and plans for the future. We will also answer your questions. After this initial, bilateral verification, we will arrange an online meeting with the manager of the area to which you are applying. If all goes to plan, we will welcome you to the team that you will have the opportunity to meet with before you start onboarding.

The recruitment interview is an opportunity to show your best side, but also the opportunity to get to know us better. We encourage you to familiarize yourself with our activities so that no question will surprise you, as well as with the requirements that we place on a person in a given position. We will ask you about your previous experiences, projects, and initiatives, as well as your strengths. We would like this meeting to be bilateral, so also prepare your own questions for us. We will answer each of them.
