This sort of thing is quite useful to those of us who have an involvement in hiring, but don't have a lot of experience.
I've been involved in hiring a couple of people, though the process I go through usually involves:
a) Read a code sample, if available. b) Face-to-face interview (telephone if face-to-face is difficult). c) Hire/No-Hire
The interview usually involves talking about our company and the interviewee talking about their previous experience. The hiring decision is usually based on "I like the feel of this guy", with some weighing up of their skill set, the job role, and also how interested they would be in working for us.
I've found this works for the company I work for. We don't hire large numbers of people, so I don't think this approach could scale - as an example, the largest block of CVs for a position that I've seen is about 10. I don't know how it would work if we got 100 CVs.
