If your recruiter is offering too low an amount that is even below the lowest market range for that role, tell them subtly what you are willing for and why. If they are not ready to raise the salary amount, try to negotiate on other perks like company stock, work flexibility, vacation, starting day of your job, etc. Even to that extent, if they can’t meet your expectations then reconsider the offer and make a decision whether the job offer is worth your ‘yes’ or not.
