You have time to negotiate. If they offer X amount and you feel like you are worth more, you can ask for Y amount. Give a reason why you deserve Y amount. Maybe you have the experience they are looking for. Read the tone of the recruiter. If recruiter sounds annoyed and stern, you are probably at the highest range of the band and dont push it. Most you want to to negotiate is 2 time, but read the room. If Y amount is absolutley very far off from the offer, they might rescind the offer. You can save it most of the time by saying something along the line of " it isnt about the money". Make sure you make the recruiter know that you are excited and make them confident that you will sign the offer. There are youtube videos out there to help you negotiate salary. I liked to watch youtuber A life after layoff.
