We’re back with our traditional PandoList this week, profiling the earliest engineer hires at some of the most successful companies in the country. Too often, we hear about these engineers’ products, and very rarely do we hear about what it was like when these companies first began. Who were the original hires, and what the heck was it like when these guys were starting out?

This week, we’ve got Facebook’s Phillip Fung, who has one of the most entertaining stories about how he landed his job, Zynga Fellow Nick Tornow, Adobe Photoshop creator Thomas Knoll, ZocDoc’s Technical Lead Jonathan Wetzel, who is revolutionizing primary care, and finally Pandora’s Eric Bieschke.
