Hello Codeforces

Every year big companies like Google and Facebook organize many programming contests, like Google hash code, Google code jam, Facebook hacker cup... I was wondering, is it really true that top contestants are offered jobs/internships at these companies? someone told me that this year everyone who reached Facebook hacker cup round 3 were offered internships and every one who reached the onsite contest got a job offer at Facebook. Can anyone please confirm or deny that? Please share your knowledge with the community.
