I think that's perfectly reasonable. Although I'm not a native speaker I quickly get annoyed at people's inability to form proper sentences. But only in formal situations, such as the job application scenario in the original article.

I went to a Barclays bank in the UK the other day to try and open a business account. One of the main reasons I didn't go with them was that the guy who was going to be my 'personal banker' could not spell the words maintenance ('maintainance') and developer ('devloper'). This just makes you seem incredibly unprofessional and unworthy of future dealings.
