What does "here we go" mean in this situation? and why did he say "we" not "I"?

He says "here we go" because "here we go" is an idiom that is said when someone is going to do something they are nervous about. Therefore, "I" should not replace "we" here because he is using an idiom. Ex: I'm about to have a job interview. Here we go!
