As City Councilperson, I have gone through resumes to hire Chief of Police, Fire Chief and City Manager. In my experience of reviewing applications, I first toss out lengthy, wordy introduction letters. I have seen 2-3 page introduction letters, along with a full work experience sheet that tend to be more than what is required or asked for.
Secondly, I look for work tenure. If they have been short term employees for several companies over several years, they get tossed.
Thirdly, I look at their experience and education. A person needs to sell themselves on paper first. They need to show confidence in themselves through their introduction letter.
I also look for spelling and grammatical errors.If the criteria is met and all qualifications look well, then I choose to interview that person.
