We have all faced challenges and overcome them, so which one do you choose to highlight for the interview? Well, ideally it is something you are proud of (which by definition means it was a significant challenge). Moreover, it should be within the professional context if possible. While it’s fine to say that you were able to climb Mt. Everest or won a medal at the Olympics, most of us will provide a great answer if we can talk about a workplace or business challenge we helped a team or company overcome.
