I just came across this article, which strongly states that coding tests are a bad interview technique. I do not completely disagree, but it really makes a lot of sense to have coding tests. First of all, it helps in filtering the kind of people who can talk a lot but don’t have enough hands-on skills. Another thing is coding tests are conducted not just to get a working solution from the candidate but to check how good his OO skills are, which after all is one of the core competencies for a dev.
