MBB is typically hiring because you already have communication strengths. Half the interview is technical, the other half is about structured communication and synthesizing "so whats" for a CIO-level audience.

I'd actually question whether working on communication skills is the right move? If you find it intrinsically valuable (i.e., it's a personal growth goal to be less introverted and a better communicator) then please listen to the rest of this thread, but if it's about career opportunity it's typically a much better investment to highly-leverage your strengths and outsource/partner where you have gaps. We could talk all day about the number of tech companies that are pairings of the uber-geek tech genius and the slick salesperson translator -- it's fine to team-up with people who have skills that complement skills you lack, and you are typically able to accomplish much more together.
