The purpose of a resume is to get an interview - period.
So what should your resume contain? Experience leaps to mind. Education looks good also. What about an abstract? or job objective? or even your "perfect" or "dream" job?
Many experts say all this and more.
My limited experience searching for qualified DBAs has lead me to believe the search for candidates is either feast or famine. Either you cannot find anyone - qualified or not - or you're deluged with qualified resumes.
So what do I look for in a resume?
First, an indication of experience. Experience is probably the most important thing for DBA work. Second, I look for... ok, all I look for is experience on the resume. If I see some, I'll schedule a phone interview.
