Minecraft villagers change jobs?

I healed a zombie villager and he turned into a farmer. I want him to be an armorer, but when I put the grindstone at his feet he just looks at me. I've already built a house for him. The videos on YouTube didn't help me. How do I change my job?

That does not work. Once a villager has his job, you can only change it in the NBT tags

Has already cleared up he has just changed his job

Your experience probably does not refer to current versions where you can easily change the profession of a villager with the respective occupational block.

Sometimes it takes time for him to take up the new job. Just waiting still worked.

Ja

No, it doesn't
