I wouldn't hire someone to work for me (in the personal finance industry) unless they knew how to use Microsoft Excel, and I would expect everyone to be able to use Microsoft Word.
Children in elementary school use Microsoft Word, so if a job candidate couldn't use Microsoft Word, I'd question their ability to successfully complete other tasks.
