On the one hand, it's not really your business. The recruitment team evidently need to sort themselves out.
On the other hand, I know what you mean. I hate when people tell blatant lies (e.g. societies they weren't in, work experience they didn't achieve), not so much because it benefits them, but because it degrades those of us who actually do bother to get relevant experience etc.
Ultimately, in your position I'd leave it be. It's not your place to get involved.
