One of the best feelings at work is when you hire for a technical
position and a few months later you realize the person you hired is a Quant (for those who have seen the Big Short, you'll get the reference). It makes your life so much easier when you have a genius diving into the numbers for you.
For years there have been certain tasks where I have to roll up my sleeves and dig into massive financial spreadheets since the people who work in my department can't figure it out. My Quant does all that now. And my Quant does speak English.
