I have no portfolio. Almost every line I've written for the past 5+ years has been paid for. When I do code for fun, it's never my best stuff because I'm mostly either trying new technologies or it's not a particularly complex problem. This approach would seem to select for pretty specific set of candidates. The current system is really easy. I prove to you I can code, we talk about technologies I like and things I've done, we talk about work style and bing-bam-boom I either get the job or not. And if I don't like the question you asked me in the interview -- why would I want to work for you anyways?
