Why are applications so poor?

I have a position to fill on my small team with a local council. I have received 69 applications, but the quality of most of them is remarkably poor. Two applications have a set of brackets: "I have considerable experience from working at [your job here]" or "I am fluent in [enter language]" which makes me think Chat GPT may have been used. Applications include incomplete sentences, at least one reads like it came directly from Google Translate, and one begins with the word "hi" and continues with the word "basically".

The covering letter or supporting statement should speak to the applicant's experience and how it relates to the role. If I have to fill in the blanks with my imagination, it may not go the way you want it to go.

Am I expecting too much?
