Yeah. When I was job hunting ~3 years ago I knew I was going to have to do a lot of whiteboarding problems. I only had two 2 years of coding experience, and for the last six months I had been freelancing, which doesn't often encourage algorithms. I was working through "Cracking the Coding interview" and "programming interview exposed" but I was worried. So I sent an email to everyone in my coworking space that I'd put a six pack in the community fridge for every person who did a mock whiteboard interview with me. Some of them came with their own problems, some of them picked problems from websites or the books that I hadn't done yet. Some of them were doing it as a favor, and some of them wanted to practice interviewing people. I got five mock interviews over a week, many of them with strangers. Best 40 bucks I ever spent. (I nailed the next real interview I had and got a job offer.)
