Interview process. From the start, we did away with whiteboard questions and instead opted for a take home test. The test wouldn't take more than an hour or two, depending on how much effort the candidate wanted to put into it. They got 2-3 weeks to complete it, with the help of the internet. Because the test was specially designed to weed out people that didn't know how computers/compilers worked, it was surprisingly effective at removing 90% of candidates. The people that got in were of the highest quality.
