I love grammar and generally, I rock at it.

“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.

In the same vein, programmers who pay attention to how they construct written language also tend to pay a lot more attention to how they code. You see, at its core, code is prose. Great programmers are more than just code monkeys; according to Stanford programming legend Donald Knuth they are “essayists who work with traditional aesthetic and literary forms.” The point: programming should be easily understood by real human beings — not just computers.

And just like good writing and good grammar, when it comes to programming, the devil’s in the details. In fact, when it comes to my whole business, details are everything.

I hire people who care about those details. Applicants who don’t think writing is important are likely to think lots of other (important) things also aren’t important. And I guarantee that even if other companies aren’t issuing grammar tests, they pay attention to sloppy mistakes on résumés. After all, sloppy is as sloppy does.

That’s why I grammar test people who walk in the door looking for a job. Grammar is my litmus test. All applicants say they’re detail-oriented; I just make my employees prove it.”

I Won’t Hire People Who Use Poor Grammar. Here’s Why.
