I can write and also translate and I have some design skills, I'm interested in those three.
I'm creating my profile, but I don't seem to be able to add more than one option regarding my job interests. Is it beacuse I'm new or is there any extra tab I'm missing?
Thanks for your help.
I know this isn't what you're asking, but it's generally not a good idea to try to hit multiple markets like that on Upwork. You're in competition with tens or hundreds of thousands of people who are showcasing themselves as experts in the one service the client is seeking...jacks of multiple trades tend to have difficulty landing jobs here.
You'll be able to add up to 10 different skills to your profile, but you can choose only one category. As Tiffany pointed out, new freelancers who specialize in a more narrow set of skills tend to become successful faster on Upwork.
