-: You should negotiate your salary,
you know what it is as a baseline.
But all they can tell you is no,
they're not going to revoke the job offer
just because you tried to negotiate your salary.
But it's tricky.
It's definitely tricky also if you are a female.
And so I my advice there is to make sure
that you know what your market value is.
And you can sort of use Glassdoor as something as an option.
But also if you have applied for other positions
and you've received an offer,
then you have a sense of what your market value is
and if your preferred position is below
what you're receiving from your non preferred position,
then I think you are well within your rights
to go back to your potential employer
and say, "I have an offer for this."
