If you are out of work or just trying to upgrade your next job careerbuilder might be a place to check out. This site has hundreds of jobs that go back at least 30 days. The problem with it is that your resume is put into a pile of thousands and so not really noticed by employeers who might come to this web to search for possible employees. But have no fear for some bucks careerbuilder will upgrade you to the front of the line and that way you can get noticed by searching employers.
The website is very popular and there by your chances of jobs posted there are excellent but the problem with it is trying to stand out. I recommand that you see which employers are looking for someone in your field and send and write them directly, don't use the site to submit your resume as the employer will get hundreds from this site in this fashion instead write an introductory letter and attach your resume to it and send it by the post office, make sure that it is professionally done (this runs between $75 AND $250 depending on which service you use) and use good resume paper and send it directly to the hiring manager( you can get the name simply by calling up the company).
