How much room is there after an offer? - what worked for you?

I want to negotiate but I am afraid they will withdraw. This is my first time dealing with any of this. I have a competing interview next week. Did you negotiate?

Ask about the range, not a number on its own. It felt more collaborative.

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.
