Mr. Selfish!
Well you asked for advice!!
Having trouble getting invited to an interview?
Firstly I would obtain the services of a very experienced writer of resumes!!
In your post, there are at least three spelling errors, poor grammar, and you used the "I" word at least eight times.
Hopefully you don't sign your applications: Mr. Selfish [Nick names are sometimes reflective of a person’s character].
Seriously, if any application letter is poorly written, and not addressed correctly, the Operations Support Folk will put it to one side, and the Chief Pilot may not ever get to read it.
Image, confidence, grooming and presentation in all its forms "may" get you through the door, but a poor application won't get you invited to the party!
