But how an audition will improve anything? The marginal improvement in the new hire quality that you get from doing an audition is not worth the time and money spent on auditions plus the cost of lost candidates who took offers that did not require auditions.
Actually, I'm not advocating auditions. I'm also really not a fan of the StackOverflow/GitHub/you-shouldn't-have-a-life-outside-of-coding approach either. But just because that approach is overkill doesn't mean that interviews should be be treated lightly (and I think treating interviews lightly is unavoidable if an employer considers firing to be a routine tool).
