Christopher McCandless: If we admit that human life can be ruled by reason, then all possibility of life is destroyed.
Christopher McCandless: You don't need human relationships to be happy, God has placed it all around us.
Christopher McCandless: I read somewhere... How important it is in life not necessarily to be strong... But to feel strong.
Answer: Chris probably knew what his Social Security Number was, and providing this could be enough to legitimately get him on the payroll. The people he worked for along the way could have been used as references. It is also possible that he was able to get a transcript and/or other documentation from Emory University; maybe a phone call to check if he graduated was more than enough. Christopher was also somewhat older and educated/ intelligent than others seeking such employment - in his early 20s compared to high school kids - which may have given him an advantage. There was probably a high job turnover rate among the employees, making it easier to get hired. Fast food restaurants tend to hire people from all walks of life, many who do not have much, if any, formal education or prior job experience; they often hire whoever applies.

Not entirely disagreeing with your answer, but having worked at a university, I can say that someone cannot simply make a phone call to obtain a student's academic information, even their own. A 1974 U.S. federal law (FERPA) protects student privacy. Every school is different, but there is usually a process requiring identification, paperwork, and signatures to prove identity. As Chris had left all his I.D. behind, it would take some time for him to get any college information, particularly from a school in another state.
