As someone who has done a limited amount of hiring, I'm inclined to think that the inconsistency is something to be wary of. It's worrying to open the blog page and be able to simultaneously see titles reading both "I Didn't Get Hired. Here's Why" and "Why didn't I get hired? I don't know why". It leads me to believe that the author does not bother checking their own work, and/or has trouble articulating simple thoughts (ie. whether or not they know why they weren't hired, a yes or no question).

To your question - would this affect the author's code quality? Maybe, maybe not. They could be an absent-minded-professor-type who can easily do genius technical work, but misses things like this. However - Google looks for more than code quality.
