This question already has an answer here:
On December last year I received and accepted an offer for Company A, a big one in the Software Dev business. According to that offer, I should start this fall.
Since the acceptance, my personal circumstances have changed. I moved to Silicon Valley and got married. For personal reasons, I want to look for a different job near my current location and reject the offer from Company A (located in a different state), but I'm afraid of the problems it will bring.
I'm not worried about the legal implications. I understand that it's me who causes this problem and I will pay the services that Company A already provided me with. My biggest concern is the bad reputation that this could bring me. The companies in the valley talk among themselves, and rejecting an already accepted offer could make me look bad. Am I being too paranoid, or are there real possibilities of me being flagged as "not to hire" in other companies?
[Edit: I don't have another offer at this moment. I plan on look for another job]
[Edit2: Company A still hasn't provided me with any benefits, only some informative talks by phone. As for the offer, I accepted by mail, I didn't sign anything. Anyway, I'm not (too) concerned about the legal or economic problems, but about the bad reputation ones. I don't want to end in a blacklist outside Company A (I already assume my future chances of joining again Company A will be close to zero).]
[Edit3: As for the duplicate links. I'm not asking if it's ok or unprofessional to reject an already accepted offer. I know it can be a dick move, but that's what I have to do now. I'm asking about the chances of me having problems looking for jobs on Companies B, C, D, etc. after rejecting Company A offer]
