When I was asked for my availability for a phone interview, it took them a long time to respond. It seemed like the person who interviewed me didn't really have any technical experience, and was reading questions off a list. I tried to walk through my thinking with a few of the questions, but it seemed like the only thing that mattered was the exact right answer. I was expecting more algorithm-based questions, like how to efficiently do a certain task... instead, all they asked me were very low-level, language-specific questions that I feel like one doesn't really need to know off the top of their heads.
