Effective listening is a skill, we are not born with it.
Unfortunately, it’s a skill that’s nowhere near as common as you’d think. The ability to listen is a career strategy, plain and simple.
There is a competitive advantage that you can give yourself by honing your listening skills. 
When you listen to someone properly, they gain a positive impression of you. In a business environment, it’s easy to see how, repeated with employees, colleagues, managers, providers and customers, this could really develop your positive profile. It tells people that you respect them.
The good news is that, regardless of how good or bad your current listening skills are, you can improve on them. As well as being a skill, it’s also a discipline. Like riding a bike or playing an instrument, it can be learned, improved and mastered. And the more you do it, the more it becomes a (very useful) habit.
Try this: The most simple exercise is to force yourself to count to 2 (under your breath of course) when you think the person has finished. If he or she is finished, great – you can now respond. If not, then continue to listen politely.
To interrupt, so “step over” someone is just plain rude, so what is the down side of those 2 extra seconds?
