I found a wide variation in the quality of information and the ease of use and navigation of the sites. CareerBuilder had some interesting interactive tools that human resource professionals could use to create job-oriented web sites for their own corporations. When its redesign is finished later this fall, it will have the best system for notifying job seekers of new jobs as well as helping them post their resumes for prospective employers. I feel it is the best way to begin a job hunt on the Internet. Depending on how this will be implemented, it could be more cumbersome to search for job seekers than searching a single database.
Some sites charge employers to list jobs on a per job basis or a per job category basis.
And there are various pricing plans for quantity listings. CareerPath does a good job with dealing with basics. For example, the home page lists the current number of jobs available today at the top of each and every page, an important reminder of why anyone is using these services to begin with. Both NationJob and Online Career have readily available pricing pages. Most of the other sites either don't post pricing details or require you to send them an email with your query.
