EDIT:
People seem to focus on the wrong thing here. I just started playing AFTER A BREAK.
Original post:
I've just started playing and I've been thinking to do some mythic dungeons and normal (maybe hc) raids. It's really hard to find a group without a guild and no prior experience.
So I gave "Find a guild" feature a try. I applied to some guilds that I thought looked interesting and had a lot of members. However, those guilds are not accepting me. They are not denying either, the request has just been sitting there for a week. Maybe "find a guild" has tons of dead guilds. I don't know.
I tried asking in chats but no reply.
Blizzard forums don't have recruitment by realm (or battlegroup). Neither does mmo-champion.
Can you now join a guild on any realm as long as it's your faction and zone?
