I give this rating because I personally don't have any difficulty using the system. I didn't have any difficulty learning the system either. I know that in my position I am taking complaints from users who are having issues with the oracle sites but most of the time it is user error or a technical issue and they need to be using it in the best way possible. I do think it is one of the easiest sites for applying online and hiring candidates. In my 10 years of dealing with so many other recruiting and career sites like Kenexa Brassring, Erecruit or Peoplesoft, I don't recommend any of those at all. Oracle CRM/Taleo is by far the easiest site for applicants to apply, the easiest site for recruiters to hire and the easiest site to manage your hires.
