If you're only applying in-game a lot of them will ignore it too because they take applications or advertise through Discord or other channels.
It depends on the guilds too, some are very strict and competitive, some run the guild to make money of running a guild, some just create one in hopes of having a full, active team playing together.
My guild Dinero Juegos is shooting for #1 Spanish guild, but we're still focused on teamwork and being a part of the community more than anything. We have a hive.blog page too which you can check out if you'd like, not any openings now unfortunately.
A big part of any guild is being active and having a decent ranking to prove you are committed to the game, if you're Bronze 2, that's essentially the lowest rank because you can't earn from battles below, so you will either need to find a guild that helps new players, or work up to Silver 3 or higher and then search. The benefits of being in a guild aren't very useful when you're in bronze either, though still good.
Here's a few great links that you might find useful!

Thank you! This is very helpful, I'll take a look at those links and try to look around for some discord pages or things like that. Also working on getting my collection up, for sure.
