Logical reasoning is required, and the ability to determine an efficient solution for the task at hand is required. Keep in mind that many of these algorithms that are tested for are not intuitive and took researchers years to come up with. What you are being tested for in an interview is not logical reasoning (as much as they claim that's the case), but rather your ability to memorize algorithms. It's silly and counter productive to finding actually intelligent people.
