Do you have an example?
The idea is that you can have different views for different jobs, but all the data stays the same. So if you're looking for a system administration job, you might leave out some of your robotics experience. If you're applying for a position working with hardware, you might want to include it.
The views are created as you need them, deleted when you don't- and you can revoke access to them at any time by re-generating the url.
