I Won't Hire People Who Use Poor Grammar. Here's Why.
I read a very interesting HBR article by Kyle Wiens about the importance of grammar and what it represents when assessing potential employees. In short, its more than just a person's writing that may be affected by their use of grammar. He writes:
grammar is relevant for all companies. Yes, language is constantly changing, but that doesn't make grammar unimportant. Good grammar is credibility, especially on the internet. In blog posts, on Facebook statuses, in e-mails, and on company websites, your words are all you have. They are a projection of you in your physical absence. And, for better or worse, people judge you if you can't tell the difference between their, there, and they're.
If it takes someone more than 20 years to notice how to properly use "it's," then that's not a learning curve I'm comfortable with. So, even in this hyper-competitive market, I will pass on a great programmer who cannot write.
Grammar signifies more than just a person's ability to remember high school English. I've found that people who make fewer mistakes on a grammar test also make fewer mistakes when they are doing something completely unrelated to writing — like stocking shelves or labeling parts.
I suggest that you read the whole article if you're interested in learning more.
