I just started job searching again for the first time in a few years and it seems like every problem has been "bumped down" one degree. So medium/difficult questions like the classic "most profit buy/sell stock" are now classified as easy, and the "hard" questions are close to impossible to solve within 60 minutes unless you specifically prepped for it.<p>Have tech companies made their tests more rigorous (in response to books and sites dedicated to passing interviews) or am I just out of practice?
