3 weeks ago I accepted and signed an internship offer letter but surprisingly and unexpectedly got a much better offer a couple days ago.
How do I politely reject the first offer after having signed the contract? I did not see a offer retraction fee/penalty in the first offer letter so this wouldn’t be a problem. Ultimately, I don't see the first firm as my future firm of choice but still i do not want to burn the bridge or sound rude.
Thanks in advance!
