A common problem I find is that companies that have open positions either do not advertise those positions on their own websites, or even if they do, they don't link to those pages from anywhere else. Lots of companies have "Careers" or "Jobs" links, typically in the footers of their pages but often at the top. They're real easy to find. But some companies have no such links. I speculate that this is because the HR department is granted access to a specific directory on the corporate webserver, but somehow it never occurs to them to ask the webmaster for a link from the homepage. Another problem is that the URLs are sometimes hard to figure out. If I speculate there might be a Jobs page, I can often guess at the URL: http://www.example.com/jobs http://www.example.com/careers http://www.example.com/careers.aspx But sometimes it's something really obscure like: http://www.example.com/corporate/join-our-team.html
