Describe what you learned and how you plan to leverage the lesson if selected for the MBA program at MIT. Also, be sure to keep your answers professional. While you may have learned in college that partying with friends until 3 am the night before an exam is a poor idea, your MBA interview is not the best setting to discuss your wisdom on that subject. If you do bring lessons like that up, be sure to phrase what you learned skillfully. For example, you might instead describe that you learned the importance of staying focused on your goals and pursuing them despite outside distractions.
