I don't follow the Shangai listings (because to me they are kinda pointless) but if pressed to list canadian universities, University of Waterloo would definitely be there....
Erm, that's well-known as an excellent school. Top-tier, really. My only qualms about inviting in a Waterloo man for an interview would be that our work might not be interesting enough.
Read Cryptonmicon and you can work out who Randy's' family is based on
edit: Your original comment (paraphrased) was, 'I go to this school no one's heard of, but my classmate get offers to <top-tier tech companies>', but the reality of this is that all of these top-tier tech companies are without a doubt quite aware of Waterloo and it's quality. The same can't be said for, what, I don't know, Cleveland State University.
