I never said I want an individualized contract, but I reserve the right to reject the offer, and I have, when the contract is unreasonable. What I want to know is when exactly to reject it wrt the confidentiality agreement.

In my experience, as a normal non-unicorn employee at a large corp, I was able to have my contract modified. It required advice from an employment law lawyer that cost a few hundred dollars and a couple emails with the company’s general counsel.

You can change these contracts. Hiring people is difficult and once the company has made that decision they don’t want to lose you over a contract clause.

I had every single one of all my contracts (as employee and one-nerd-business) adapted in minor or major ways.

I am good at what I do, but no unicorn and not FANG "level".

But then again, I don't live in the US

As an average Joe, I was able to negotiate employment contract changes every place I worked in the tech industry in California in the early 02000s. I don't remember having been faced with contract clauses that I felt needed alteration as an entry-level tech employee in the 01990s.

You may have misunderstood the topic, which, I'll remind you, is confidentiality agreements that act as lifetime non-competes, which means for the rest of your life after you are employed by an employer in the same industry, not while you are employed by an employer in the same industry.
