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

It is the first offer in 2 months and I do not want to mess it up. I have been trying to stay organised about it. I have a competing interview next week. Did it backfire?

I thanked them and said I was excited but hoped we could talk about the pay. They came back with a bit more.

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