Ahahaha, oh brother.
You need to care about how much I'd make at another company, because if you dramatically underpay me, I'm walking. I'm ok with fuzzy variance - a few K/yr isn't making or breaking me. But if you short me and give me <90% market average, I'm job hunting. I don't care about how much I like the job - you simply are not valuing me as much as other companies do, and that's unacceptable in my eyes.
Unwillingness to negotiate is a red flag: it signals you can't work with me, are inflexible, and are not interested in accommodating me if something comes up.
So no. Negotiate with me and offer at least 90% of market value. Or I will walk - either I'll join and quit as soon as I get another job, or I'll keep searching. Neither are good outcomes for you.
>The first part is very personal. People having mortgage and two kids just overvalue themselves. Immigrants in US (and I guess everywhere) just don't need as much money as they don't see the neighbour's grass. Can you explain what you are saying here? Are you saying that only immigrants are willing to take the offers you make, or that you make higher offers to people who overvalue themselves?
I'd walk rather than accepting an offer that truly can't be negotiated, because if the company is so inflexible that they can't even yield a tiny little bit, then that's a huge red flag to me.
