☛ The person is checking your thought process. They don't really care about how much you know about ADDIE, Dick & Carey, or any other design model. They want to hear you speak, they want to check how you approach the entire spectrum of training.

☛ They may also be checking your work style or work ethic or may even use this as a way to get you to talk more about your experience. If this doesn't come a place in the interview where there's a natural segway into - okay - tell me about training (or if you are a seasoned person with training experience) then this may represent an attempt to gauge exactly what working with you would be like. Remember, employment really is a two way street. Managers/Bosses can get just as frustrated with an employee as you might have gotten with a boss at some point in your career.

☛ Additionally, the interviewer, again depending on the timing of the question, may want to check your ability to analyze a situation and/or problem solve. This type of question is the generic equivalent of "tell me about ____ (this position) or (this project) ". Again, this is not the time to theorize about a model or a theory. It's about your power to observe, assess, and respond to the work environment and its demands.
