Are there any diff between a person who speak one language and a person who speak two language? how?

I mean I speak both Spanish and English, so sometimes I have to translate for people. I also got a funny accent too, but that depends on where the person is from.

Actually fun fact, people who speak 2 languages are more likely to get a job than a person who only speaks 1. I speak english and spanish as well as do sign language because my sister is deaf which means I would get a job way faster than a person who only speaks just one language.
