I know this is a caste thread, but there might be a more general issue at play here - a mediocre person may not be able to recognize a talented person, a good solution or a good design. Not putting mediocre people on interview panels would be way higher on my list before getting to cultural or discrimination issues. I am almost inclined to bet that more talented people are less likely to discriminate anyway based on race caste etc... because they don't have the same insecurities.
