Taleo's been around for well over a decade at this point, and it's pretty terrible. As a serious job seeker, the interface barely works. I was sent to the beginning of my job application after having the nerve to click "Next" in the middle of the application process, and, after having started over again, was notified of a system crash upon attempting to submit the job application after finishing... and then being told by the system that my profile no longer existed, and I'd have to create a new one.
Yeah. I tried again a day later and it finally worked, but if you're looking to frustrate your potential employees to the point of giving up before you ever contact them, Taleo's the web app for you!
