Probably, but you'd expect that because the interviews only test part of what is required to be a good employee. It's just a in-precise filter - a bar they force you to jump over, which if you manage to do so pretty much proves you're not hopeless (and have enough dedication to learn the material). So amongst the guaranteed-non-hopeless people there is fairly random distribution of ability to perform well in the company.
