See, I saw that problem in the kid's sense of entitlement to an employment opportunity he's apparently been vaguely offered and thought that's the sort of mistake a naive kid might make

I also saw an arguably-too-informal response from the author which completely failed to address that problem, noted he saw it fit to publish in a blog promoting "workshops on how to attract and keep young talent" and thought that's the sort of mistake somebody promoting himself as an employer-youth communications guru really shouldn't be making.

I didn't see too much wrong with it (it seemed like he was genuinely busy and explaining what is going on)... until I got to the part that said "... hearing what you might be able to offer me." Not an appropriate response for someone offering you a job.
