This is handy for a quick job search, but, do keep in mind that all you're searching is the jobs listed in Google Base. At the moment, that's about 1.5 million listings. Compare that to the over 5 million jobs searched by SimplyHired, for example, or the more than 2 million jobs posted on America's Job Bank. You won't necessarily find the same job postings on every job sites. So, it's important to use a variety of job sites, including job search engines, local job sites, niche sites, and the top job banks.
