Jobs's primary test for recruiting people in the spring of 1981 to be part of his merry band of pirates was making sure they had a passion for the product.
He would sometimes bring candidates into a room where a prototype of the Mac was covered by a cloth, dramatically unveil it, and watch.
"If their eyes lit up, if they went right for the mouse and started pointing and clicking,
Steve would smile and hire them," recalled Andrea Cunningham.
"He wanted them to say 'Wow!'"
Bruce Horn was one of the programmers at Xerox PARC.
When some of his friends, such as Larry Tesler, decided to join the Macintosh group, Horn considered going there as well.
But he got a good offer, and a $15,000 signing bonus, to join another company.
Jobs called him on a Friday night.
"You have to come into Apple tomorrow morning," he said. "I have a lot of stuff to show you."
Horn did, and Jobs hooked him.
"Steve was so passionate about building this amazing device that would change the world," Horn recalled.
"By sheer force of his personality, he changed my mind."
Jobs showed Horn exactly how the plastic would be molded and would fit together at perfect angles,
and how good the board was going to look inside.
"He wanted me to see that this whole thing was going to happen and it was thought out from end to end.
Wow, I said, I don't see that kind of passion every day. So I signed up."
