I just wanted to throw some questions and answers I would give to each of them because I think they can help more people, I will say I don't always have a great answer but I do my best to respond with what I can to help as much as possible. If this gains traction I'll try to keep adding to this thread as we go (I have a ton of other questions in my DMs).
I think this varies a ton especially between countries, our company has some overseas employees but the main (full time) one started with us while he was in the U.S. and then the other is a relative to him.
I'm not really on the security side, but I try my best to be as secure as possible. I would say the best piece of advice anyone can give in any tech field, is never stop learning and never be afraid to ask questions. Out of all the people I've trained that's what I see people struggle with the most.
