search – Filtering with multiple choice according to OR, AND previous selection

I'm working on a site where users have to filter candidates (HR site) in different ways … The problem, for example, they have 6 options displayed with checkboxes, they select 3 options they can expect that the result can be candidates with these 3 options at the same time or candidates who could have one …

How do you think the best way to filter with these two options?
Do you think it's clear if we offer the user both behaviors?

I think a good way could be to show a change before the options where you choose if the selection is a kind of OU – AND …

Thank you in advance.
