UCB Director interview questions

Had 3 rounds of virtual interviews over the course of 2.5 months. Part of the team was in Brussels, so some morning interviews to make the time zones work. There were lengthy gaps between each round in which I heard nothing from them and then was later told people were out on vacation for several weeks. In the last interview, they said they wanted me to speak with a couple more people and someone would reach out to schedule. Never heard from them again, despite my following up on several occasions. It felt extremely rude after such a lengthy process. I will not apply to work here again.
