The first interview was a brief phone screen, but the second interview was approximately four and a half hours--an hour-long writing test involving four prompts (never mind the fact that they had already received my portfolio), followed by interviews with the marketing team, the communications team, some stakeholders, and the head of the entire department.
Everyone was friendly and welcoming enough--but asking candidates to clear nearly five hours on a workday morning is unreasonable and unnecessarily time-consuming. That being said, if you're going to do it anyway, at least have enough respect to tell people you've rejected them, instead of telling them you'll get back to them in a week and a half, then leaving them in limbo for nearly three weeks until they email you for an update and receive a bland, copy-paste rejection the next morning.
All in all, the people genuinely did seem fine, but the process ended up being time-consuming and demoralizing when it really didn't have to be.
