☛ We're back to the tree/forest concept from earlier. Training is about both details and the big picture. In a business setting, it's about the needs of the learner balanced against the needs/demands/constraints of the business.

☛ This type of question also allows insight into your decision making process. Businesses need people who can make decisions while learning from mistakes or missed opportunities. It's a bit complex at time, but in reality, good training programs, on any level, are about knowing what approach to take and what to not do or not to include.

☛ A question such as this also allows you to show how you learned and grew professionally in a roll. Everyone knows next to nothing when they start out. Everyone also does not know what they don't know. Still following? So being able to relate how your work, your tactics, your approach, your design, etc. changed as you grew and learned is a great way to show yourself off. But be wary again - be specific and be precise. There's a fine line between self-awareness and bragging.
