You are assuming a lot. Many stanford phd's /dont/ fail the google interview. I'd guess larry, sergey and zuckerberg had a pretty good chance of /passing/ their own swe interviews...
You might be semi joking, so apologies if I took it too literally: I'm assuming nothing really. And we are saying almost the exact same thing. Many pass, many fail. Pretty good chance of succeeding, pretty good chance of failing.
