I have the luxury of living within walking distance of the office. At the end of a working day, I unwind as I walk home and then I exercise at the gym, play squash or have dinner with friends.


What do you love about your job and your employer?

My job is dynamic and challenging. One day my diary is dominated by meetings. The other day, my diary is fairly empty while ad hoc tasks or hurdles pop up during the day that require adaptability and flexibility. Relatedly, I enjoy the many responsibilities you have as a project manager to move the project forward. The focus is on constantly improving project execution and solving problemens where necessary taking into account time, buget, and quality constraints. Besides these hard skills, soft skills are also important when working with the customer, your suppliers, and the internal project team.
