be ready to walk away from their offer. Thats the only secret for negotiations, there is no other secret sauce.
>Them: The offer is for $X.
You: Thank you, but I will continue my final interview process with [CompetitorA] and [CompetitorB]
>Them: How much more money do you want to accept our offer and terminate interview process with our main competitors?
You: Add Y% and I will sign the job offer right now.
This approach doesn't require you to lie, or photoshop fake offer letter (like some bad people advice on places like Blind), and doesn't require you to arrange a direct bidding war - all are huge red flags for any employer.
Again: Be honest and upfront, full integrity, never lie, dont make it about money, but rather about the mission of the job
