How are the video games designed for the major consoles designed?

Do the big companies like EA, Activision, Ubisoft, ect use C++ or C#, or do they have their own special programs for making games, or maybe possibly a certain kind of computer.

I’m interested in getting into being part of making video games with the big companies as a career but I don’t find all the coding too interesting. I would be more into using different programs to design the games rather than typing codes down.
Any insight would be really helpful.
