As you advance in your career, your audience changes. You're no longer just communicating with your direct teammates and manager. You'll be asked to present your work, your ideas, and your results to people several levels above you: Directors, VPs, or even C-level executives.
These conversations are high-stakes and require a completely different communication style. Senior leaders are incredibly busy, operate at a strategic level, and have little patience for rambling or unnecessary technical jargon. Your ability to communicate effectively with them is a key indicator of your leadership potential.
Answering this question well demonstrates that you can think beyond the code and connect your work to the strategic goals of the business.
