Ask HN: Professional Resume Critique?

Hello HN,

I've been wondering what process you all use to get your resume looked at. Is it worth paying for some sort of professional service, if friends/colleagues have already looked over it?

I've also heard that a lot of hiring these days uses automated services to screen resumes. Can anyone who works in recruiting share anything about that? Is it all about keywords + gaming the system now?

I feel like I haven't given this as much thought as I should, and given that resumes are the bulk of what I submit to job apps, I figure it'd be good to get some more perspective on this.
