How do you defend a 'Why IB' answer when your profile has clear inconsistencies, such as four consulting internships and a sudden IB application?

Own the path. Explain what each experience taught you, then identify the moment you realized transaction work fit better. Do not pretend the CV was always perfectly planned. A good answer says consulting built problem-solving skills, but banking is where you want to apply them to valuation, financing, and live corporate decisions.
