There's a reasonable expectation to have to demonstrate one's skills in an interview. Whether any given test or set of questions actually is valid for doing that is another matter entirely. Put another way: it's just as unreasonable for a company to expect a developer's skills to be measured by contrived tests or to demand they spend any unpaid time at all doing "work" (e.g. projects), as it is for a candidate to expect a company to effectively kiss his butt and lay out red carpet just because he decided to apply.
