Steve Jobs exhibited a unique personality characterized by a mix of slim yet peculiar intensity and a detached rebelliousness. This attitude often led him to isolate himself from his classmates, including McCollum, who noted that Jobs preferred to work alone rather than engage with others. He was so unpredictable that McCollum never felt comfortable giving him a key to the stockroom.

In one instance, after realizing he needed a specific part that was not on hand, Jobs made a bold move by calling the manufacturer, Burroughs in Detroit. He claimed he was designing a new product and requested the part, which was subsequently sent to him by air freight. This demonstrates Jobs' resourcefulness and willingness to take risks in pursuit of his innovative ideas, a trait that would define his future endeavors.
