Although your professional pursuits might possibly remain the same, thoughtfully explain to your interviewer that through hindsight, if given the chance to start again, there are probably a few things that you would do differently. If you were starting again suggest that maybe you would pursue different course work or another college major, or even a different school. Maybe you would learn more about other facets of your industry. You recognize that other kinds of training might help you achieve your goals. Another possible direction for your answer might be that you wouldn’t change a thing. You are proud of the way your career has progressed, the accomplishments you have achieved, and the opportunities you have in front of you. Be careful not to sound glib, cavalier, or insincere, and say anything negative about yourself, past employers or anyone else!
