PCMag.com just released their list of The 20 Best Job Sites. The list features some familiar sites such as CareerBuilder.com, some sites that were new (to us at least) like TheLadder.com and some sites that just made us go hmmm… (Craigslist?! Really, PCMag?). While the list was lacking one or two essentials—mediabistro's stellar job listings is no where to be seen—overall it was an interesting look at the vast possibilities and opportunities available for job seekers right now.

1) Beyond.com Beyond claims to be the “largest network of niche career communities" on the Net. It essentially hooks together different organizations like PRJobForce.com and PhillyJobs.com all in one place, which makes it easy to find leads in your community.

2) CareerBuilder.com As the Web’s biggest job site, CareerBuilder gets more than 23 million visitors a month. The company has been around since 1995, and has developed an incredible network of listing sources and job search centers since that time.

3) Craigslist.org The granddaddy of online classifieds gives those who are focused on searching for jobs within their communities an easy way to look. It might be one of the least-polished entities listed here, but the sheer number of local job listings makes up for it.

4) Execu|Search This site looks to be a selective, higher-tier job search property. Execu|Search screens and reviews every resume that is submitted, and helps employers find the best possible candidates for their open positions.

5) Hound Hound's search engine shows jobs from employer Web sites only. In theory, this cuts out duplicate listings and shows opportunities that are not posted on other job boards.

More sites after the jump.

6) Indeed Indeed works as an aggregator for listings from major job Web sites, company Web sites, associations, and other online sources. Its simplicity and ease of use are its best features.

7) JobCentral JobCentral is a service formed by a nonprofit consortium of U.S. corporations like IBM and Dell, which makes it ideal if you're looking for corporate job listings.

8)JobServe JobServe claims it was "the world's first Internet recruitment service." In 2008, JobServe advertised more than 2.5 million jobs across 15 industry sectors.

9) Jobster Jobster uses an active approach to help employers and recruiting teams of all sizes find their candidates. The company calls its method "social recruiting," and it services 24 different job categories.

10) LinkedIn Best known for being a social network for professionals, LinkedIn also has thorough job listings, some of which are exclusive to LinkedIn.
