We interviewed a person a number of years ago now in a similar boat.

We'd asked him how proficient he was with a number of technologies he'd listed on his resume, and he didn't seem to know what any of them were.

Finally, frustrated, we asked him why he'd put these things on his resume. He said "my recruiter told me to". Sigh. I don't know for certain but I believe we didn't work with that recruiter again.
