I will say this from my personal experience. I've been working in the financial sector for over about 8 years now and in those years have yet to encounter a colleague who is as efficient and productive as I am. And I attribute my skills and abilities to the many hours I've spent playing Starcraft back in college. Playing Starcraft taught me how to manage and multi-task efficiently by taking the time to learn and get accustomed to using hotkeys. Sure it's slower than clicking at first but once you have the shortcuts down, damn I just blaze through my work.
Every once in a while, my managers and coworkers would come up to me to discuss certain issues encountered for the day so we can try to figure it out together and they'd be like, open this, pull that up, do this do that, etc and without putting my hand on the mouse I'd have everything they asked for opened with a few keystrokes before they even finish their sentence. And every time without fail, they'd be gobsmacked at how I did it.
I wish I could put down that I was good at Starcraft in my resume cause personally, I feel it carries more weight about my abilities than some of the other stuff I put on it to make it look nice. And I didn't even played competitively.
