I'm a firm believer in job sites now. It took me a while to warm up to them. My recent experiences with one has made me a firm believer, however. One thing about job sites is that the best ones are dedicated to a particular field, such as
medical job sites for people in the medical field. It can be a lot harder to find what you are looking for in a mass site that caters to many different jobs, and employers gravitate toward specific sites more often as well, so you are more apt to find the perfect job at those sites.
