These sessions are crucial for teamwork in solving complex issues, socializing, learning from each other, and experiencing our culture.
Each division has a pre-set optional office day each week. Based on our preferences, we come together at our offices at our discretion as an opportunity to feel more team spirit, immerse in our culture, and familiarize ourselves with our way of workings.
We offer the opportunity for a two-month full remote work program, allowing you to work from abroad, during the summer period (July to August).
