I think you've taken my post a little out of context. lol I wasn't suggesting that if you "mess" up the maths test then that might be acceptable. Nor was I suggesting that if "your face fits" then you are a shoe in. This isn't American politics we're talking about here!
What I was actually saying is that I'd rather make a couple more mistakes than my competition and outperform them in the interview, than the other way around. I think it'd make more of an impact. And although the various tests are all important, I do believe that the interview is individually the most important. Yes if you fail maths or physics it doesn't matter how good you are in the interview; you're out. But for the marginal cases, I believe the interview will be the most significant differentiator. And it has nothing whatsoever to do with how "your face fits". My initial post was referring to the quality of your interview answers, not whether or not you fit some arbitrary stereotype.
