Obviously, not viable for a new grad but it should be a goal. My career has been long with many failures but also notable successes and certain rare, valuable skills. In one recent case I was resigning my position to take some time off and do other things. I was senior, only a couple levels under the CEO at a very large F500 multi-national. The company really wanted me to stay on for a year or two more.
I generally liked the work and the people and they offered even more money to stay but for me one of the issues was that the inevitable HR policy creep was adding stuff like mandatory training sessions that were getting tedious and annoying. Basically, liked the work but hated the bullshit. So we made a novel arrangement. Any mandatory policy at the company requiring my attendance was optional for me. In the case of "specifically mandated and enforced compliance with a relevant government regulation" my boss had to explain why and just ask me. (I'm not unreasonable and there are a few SEC and state regs that they really can't just ignore).
This worked out very well and was a small but meaningful concession that really cost them nothing.
As far as I know, only the USA has gone so far as to ask for social media accounts for some visas. (I might be out of date)
E: I'm speaking more about job applications. The US Visa application requirement is of course already being litigated, and hopefully will soon not be a requirement any more.
That makes a lot more sense!
So, yeah, it absolutely does happen and to different (sometimes frightening) degrees.
Most people are not on Twitter or Insta the only possible 'odd one' would be Facebook, and you can say you deleted your account a while ago.
That leaves not much.
I can assure you, our value over time exceeds that of dogmatic thinkers. That's because, by the time you believe something, it's no longer true and we know that to be a fact before you do because we don't buy into this story.
