Demonstrate to your interviewer that you value continuous growth and learning opportunities by discussing a recent project that particularly piqued your interest. In most cases, it's best to focus on a professional example, but it's okay to discuss a personal project as long as you can give a compelling reason why it's relevant to your current work.
Maybe a project put you out of your comfort zone professionally, or perhaps it had a far-reaching impact. Reflect on what made the project meaningful and the top thing that you took away from it.
