Can I move to Korea and find a job without a visa or Korean language skills?

Hey everyone! I'm Ukrainian and currently living in Barcelona. Lately, I’ve been thinking about moving to Korea to work, but I’m a bit lost on how to even start. Right now I don’t have a visa, and I’m not really sure what the process looks like. Do I need to find a company first that can sponsor my visa? Or is it better to just go to Korea and look for a job while I’m there? Also, how important is speaking Korean for getting hired? My Korean is super limited at the moment. For context, I’ve worked as a florist, office admin, and purchasing assistant before. I'm pretty open to different kinds of work. Would love to hear from anyone who’s been through something similar or knows what the first step should be. Any tips would be super appreciated 🙏
