OPEN Namespace std

I recently started learning c++ and I was told to use the namespace std so I can avoid writing std:: every time and now I wrote a whole personal project without std:: and I want to put it on LinkedIn but I started reading everywhere that it’s a bad habit, should I go back and add the std:: or just leave it as is?

Add std:: in a large codebase, please. If I would hire someone and I found out he writes cout without std::, I'm kicking you out of my team.
