We suffer from adverse selection bias (as does any online job application). Many companies don't even hire from their online applications for this reason (instead using referrals). The truth is that almost all of the people we don't interview would not have passed (we have a small control group that we always interview, to measure our false negative rate). We do certainly make mistakes (our false negative rate is not 0). But I am proud of our process. It's more open than any other interview I know of. We routinely find awesome self-taught programmers who no other company would interview.
