<prompt> Human: So Ive recently been offered a job that Im certainly interested in, but not fully committed to accepting due to several details namely, spending a number of undetermined months in a developing country. Anyway, in the offer letter it mentions that the job is under an employment at will policy. I want to keep this job as a back up in case I dont find another one by the time i graduate. Can I respond to the letter with acceptance, and then go back on that even before I start working there, without penalty?  <response>: Its kind of a dick move but sure. You wont be the first person to back out of an offer or quit right after starting. If there is a signing bonus youll likely have to repay it
