Not sure how locked your computer is but everywhere I've ever worked, it's been trivial. Email the source file, zip it and upload somewhere, pastebin temporary, airdrop it, usb sticks.
My client is in the financial industry and have to use their equipment as a remote contractor.
The win10 laptop is locked down tight, including removable drives disabled, DNS forced through corporate servers, SSH blocked outside network, etc. I wouldn't be surprised if all activity was somehow centrally logged for compliance too.
I had to request permission to whitelist my VPN account to access Github.com. Even with VPN disabled the laptop still uses corporate DNS.
The security policy is designed to prevent theft.
Of course there _are_ ways to circumvent these protections but you'd be in a world of legal trouble if caught.
Working in the financial industry as well, not as a contractor but within the organisation itself.
To add to the above (everything is quite the same in my case): pasting medium chunks of data to external websites is restricted on the system level, same for uploading documents/images; emails to non-corporate addresses are scanned.
You would do that? Now I'm beginning to consider if I should be asking candidates to bring some intellectual property owned by their current/previous employer as a filter.
I am not saying I would do that (I wouldn't). I am just not sure how a computer can be locked down so tightly that it is impossible to send text from it to another computer.
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.
All of those things you mentioned? Blocked. As an example, if I even plug any sort of device like a usb stick or an external drive to my machine, the computer locks up and security is on the phone with my manager within seconds.
