I thought I had a pretty good resume after I completed it. Just about two pages long. I've had many recruiters reach out and I would submit it to them. I always thought to myself that I hoped to have all the keywords to help me land a new position along with a detail description of projects I've worked on. I've had friends and colleagues review my resume, but I never had a professional resume writer review it. So recently, I had one done on a site called Top Resume. They did a very nice job critiquing my resume. There were many things that I didn't have on my resume that I should. Keywords that are being missed when employers are searching for them. I think it's worth to have a resume writer review and critique your resume (It's free). Then decide to pay the $100-$200 to have a pro write it for you. It could be an investment towards the job you're looking for.
