Posted a comment in the above tread. To add to that everything one sends to print is being monitored. That leaves a room for leakage but it also makes the leakage tracing relatively easy, unless you have stolen other employee's ID (which is required to print), but do we really want to go that far for a job interview?

There are, of course, ways, but some organisations make the overhead way too big to bother.

I personally know of a case where the 'core team' of a major payments processing system was running development being completely isolated from the internet due to security reasons. Need to check stackoverflow - sure - have a walk to the cabin where you have a dedicated machine connected to web for that. Oops, and no copy-paste, sorry.
