Here's a company employment dataset from the University of Waterloo showing where students go from one internship to the next: https://csclub.uwaterloo.ca/~vlyubine/co-op
In this dataset, ELO is employed such that companies earn points if they "beat" another one, which loses points as a result. That is, if someone hops from Company A to Company B, Company A earns points and Company B loses some.
Among Google, Facebook, LinkedIn, etc., it was found that Palantir was the only company that never lost a student to another one. If you go to the companies dataset here and sort by ELO: https://csclub.uwaterloo.ca/~vlyubine/companies
You'll note that the rankings are: 1. Palantir Technologies 2. Twitter 3. Facebook 4. Google 5. A9.com
It appears that Palantir also beats out fellow big corps as well. I think the consensus among Ivy leaguers I know and Stanford/Waterloo is that Palantir's strict hiring criteria and unique culture make it the newer Google of today.
