I have found CVMinder really easy to use and I haven't need any documentation or online help to be efficient with it. There is no prescriptive workflow, but there is a visible process. That means that I can do things in the order that I need. I love the fact that automated alerts have resulted in placements and I like the fact that I don't have to upload CVs and create candidate records; the candidates do that for me.
I can share the responsibility for parts of the recruitment process with others and I can get a top-down view of everything really easily. For instance, I really like CVMinder's employment checks and how that is shared with a trusted administrator here. When my boss asks me where our best candidates are coming from, I can show him. It's all very simple.
Support is first class. I use it very infrequently, but it's a comfort that I can also send candidates to their support desk if they ever have an issue.
