As a computer scientist at Microsoft (14+ years) who interviewed many, I would say that the most important part (over which good college you are from)is how much you know about the theory of computer science , coding algorithms etc.
Interview process at Microsoft is very through including 7-8 hours of interviewing at the white board answering many algorithm questions. Interviewers start with saying that answer to the coding problem can be implemented in any coding language chosen. So starting learning JavaScript vs C is irrelevant (though C is much more respected coding language than any scripting language)
In short, which college you are coming from is not that important as long as you prove your knowledge of coding at the interview. In the interview, nobody gets threated differently just because they are from Stanford vs MIT vs University of Washington etc.
