Here's a fun little tidbit from a talk by Adam Lashinsky,
author of Inside Apple,
at LinkedIn's headquarters. In it, Lashinsky and a member of the audience shoot back and forth about Apple's rigorous interview process, which can last up to nine months
or longer. They also touched on how Apple is able to maintain its (nearly) impenetrable veil of secrecy, a big part of which is hiring people they can trust. "But how does one prove their trustworthiness to Apple?" I hear you cry. By working on fake products.
