Does Google hire from Hansraj College?

No, if you mean hiring through on-campus placements. Google does not search for profiles at Hansraj College. You can still apply through off-campus placements.

If you are searching for a technical position, you should be aware that Google no longer visits campuses (with the exception of IIT-B and IIT-D) for placements in such positions. There is an extensive off-campus employment procedure that begins with applying for an internship at Google. You can apply regardless of where you graduated.
