I've been both hiring manager and a member a team in choosing new staff. The advice I'd give to job seekers about good resume writing is to write like a real person! Don't talk in jargon. Write as though you were really talking to someone.
If a person looks like they would be a good person to work with and have qualifications, especially qualifications that are needed or even lacking by the existing staff, I'm going to seriously consider that person for the job.
The most common mistake people make when writing resumes is writing by a formula and not like themselves. Of course, it always pays to proofread. No one expects perfection when you actually get the job; however, typos are nearly the one thing that people can easily pick out and therefore pick apart.
