I wish I could take this advice, but my imposter syndrome is just too strong and you cant just turn it off with logical explanations.
By the time I get an offer, I already feel like I’m already uncomfortable about all the bragging I’ve had to do to hype myself up. Asking for more in a negotiation is just a recipe for even worse guilt during the onboarding process (which is already a fraught time for feeling like an idiot).
The simple thing I tell people to do who are uncomfortable with more complex negotiation is, just before you're about to accept the offer, just ask if they can increase it any. Just straight up say "Is there any room to increase this offer?" If they say no, just accept it. If not, let them increase it, then accept that increased offer. I've gotten an increase at a significant majority of companies doing this and it's essentially zero cost.
How many different companies have you worked for?
Close to 20 now I believe all time.
Imagine meeting co-workers on your first day: "This is parpfish, a rock star who is making twice what all of you make. He is one of those 10x engineers you all hear about. Just stay out of his way while he re-architects all our systems!" I think I should have taken the lower offer?
The hope would be to get an intro like “This is parish, a normal 1x coder that makes a normal amount of money so please be forgiving when he doesn’t understand something”.
