This question is about finding out if you are interested in continual learning and self-improvement. Businesses are constantly changing and adapting to stay competitive and profitable. This means that as the company changes, its workforce needs to adapt too. This is also why employers, when making hiring decisions, look for candidates who are proactive in their professional self-development. You should be prepared to answer questions about self-development and how you consider yourself a life-long learner. Start by writing down the top courses or workshops that you have completed in recent years. Include a short paragraph or bullet points on how you benefited from that course. Your goal is to present yourself as someone eager to learn and develop.
