I went t through three separate interviews, and was told that they would give back to me within the week, several months later I still haven't heard back. Which isn't a problem but you can at least inform candidates that they're no longer in the running for a position.

The interview process was pretty standard and they asked simple PM questions, a couple of behavioral-based questions, and allowed me to ask a "non-tech" question which they then stole and used in interviews ever since
