Meet some of our past and present interns

We value our interns enormously. We provide the relevant work experience that helps students put their education into practice and develop the leadership skills that give them a competitive advantage — whether they are pursuing a permanent position or further study. With this aim, we generally accept three interns per academic cycle. In turn, interns keep us at the height of innovation in our field. We welcome their inclusion into our very diverse team — not only do they develop their confidence, they enrich us with theirs.
