When I was interviewing for a new software job a couple years ago every company wanted to know details about past projects. What I built, what technical decisions I took, what scale I operated at, what the setbacks were, what was the final result. Some companies even made the round presentation style, like a real tech spec review, and you had to present slides and architecture diagrams. And the project had to be real, something you had actually worked on at your current job.

"But all this stuff is confidential, I can't really talk about it."

"Well too bad. If you want the job, figure it out."

So I did what probably thousands of engineers in silicon valley do every day, and leaked company IP. It got me the job, and I'm pretty sure all the interviewers forgot about what I said 5 minutes later. But in practice every tech interviewee and every company doing interviews today (including Apple) can be charged with most of what Apple is alleging.
