Here secrecy is a part of day-to-day life. Security checks happen every now and then. You will be asked to stay back at your desk, lock your computer, hand over the mobile to the authorities. If you recieve or need to make a call during the security check you need to ask their permission and your call will be monitored.
If your phone data could be backed up, it would be backed up for later analysis. All your recent activities on the phone would be checked very thoroughly. No matter, if it was with your doctor or lawyer or your spouse.
Well, you could refuse to oblige, after all it happens in a free country which fights for the freedom of other nations. But, you will be asked to leave the company right away and never bother to come back.
Can you sue them? of course not, as it all happens after signing up the NDA and all necessary legal documents.
Mind you the workers are not unskilled uneducated workers. They are the best in the business. Sometimes they work on products even without knowing on what they are working and why they are working. You literally have to cross seven oceans and seven hills before you can work on the actual product prototype. Secrecy is just their second skin.
This company is no sweat shop, but one of the most coolest, most innovative, most popular with cult like customer loyalty. Their products restore a child like sense of wonder to our lives.
And all the above mentioned secrecy and security check is just another day in business leading to "there is one more thing" showmanship of their CEO during the product launch which more likely happens with prior strategic secret leaks leading to million dollar worth of free publicity in rumor mills.
Alas, recently one of the prototype found its way to the internet in all naked glory. All because of a german beer and a birthday bash.
But the point in question is will you be willing to work for this company with your privacy as the price? I WILL!
Based on this and this
The California police seized the computers and servers of Jason chen, the editor of Gizmodo.com.
Gizmodo got hold of the next iPhone to be released and published the pictures with a tear down analysis. Apparently it was left by an Apple employee in a bar on his birthday bash after having some german beer. Apple legal wrote a letter to Gizmodo, how they could get back their property. Gizmodo replied with jason chen's address and Apple gatecrashed his house when he was not there, of course with a warrant.
