Well I got hired in 2005 with the worst handwriting and spelling ever. I think its just one last thing they can throw you out on if they are on the fence about you. But if they like you and want you they probably just laugh at what you had to say and how cheezy it was.
Ha, ha, I saw that letter and drawing hanging in an HR cubicle, I assumed it was their childs work; guess it was a pilot applicant!!
