If you remember a while back, SitePoint had an article about creating the "perfect job posting site" with the ability to link resumes with open positions and have a nice, simple job posting site that would allow people to submit those resumes to you. Well, they have up the second part in the "The Perfect Job" series this morning, and it dives more into the admin side of things.
They start off with an explanation of what the admin system will help you with, then it's straight into the code. As always, they give you all the code you'll need to add/remove/edit entries in the job posting table and search the resumes submitted to find the qualifications that you need for certain jobs.
There's also all sorts of little things to deal with when you have a system like this, and they try to cover a few of those - such as viewing the resume details, handling errors, and some of the other search options (sans code, unfortunately). MySQL full-text searching could be a good match for something like this though, instead of the LIKEs that they use...
