I believe he's still an undergrad, I don't know about google but here an intern can be anything from a pre university student to someone finishing a phd.
Exactly. It’s not unheard of for “intern” to just be HR’s shorthand for “someone who is working here for a fixed timespan before returning to a university”. I know of a 40 year old professor who spent a summer as an “intern” at Apple circa 1990.
