EE - Testimonial - Advanced Negotiations - Sonja Hamann

Sonja Hamann

Head of User Experience at a banking group in Switzerland

This was as tough as it was valuable, as there were many group negotiations with complex dynamics. Nevertheless, I am very proud and grateful as the whole program has had a positive impact on my day-to-day business and life in many ways.
