contract negotiation requires human interaction. the "redline the clauses that are unacceptable to you" statement should be treated as non-literal. you don't literally resubmit a document with struck text. you get on the phone and talk to the hiring manager.
Mhm! This is something any professional should learn to do early on. You can literally print a new document and show them the changes you've made, but you still have to interact with the person hiring you.
