I like the way it presents all of my job searching options in one place, so that finding new opportunities to apply for becomes easier than ever.
The interface could be made more intuitive - you can't seem to do anything without having to click multiple times or go through complex menus before getting where you want to go! However, this has been improved since our last upgrade from version 4. We've had no issues with performance but have not used it enough yet to provide feedback on any potential bugs as we haven't seen them ourselves. It's great at tracking applications across different companies.
