Don't try to bullshit your way through anything. It's actually a strength to admit that you don't know something. Bonus points if you can describe the resources you would use to learn the answer.
Almost a repeat of the first one, but slightly different. Don't play buzzword bingo or you'll sound like the 5th grader that just learned a new curse word and is showing it off on the playground. It's fine to use the industry jargon in appropriate ways; just be sure you know them.
It's an entry level position. The kind of skills and initiative they're going to be looking for is the desire to learn, the ability to correct/improve documentation, understanding/following procedures, thoughtful suggestions for improvements, and having enough confidence and competence that they don't have to babysit you constantly.
Networking / servers / security really covers a lot of ground and it leaves me wondering exactly what it is you're saying you'd like to do. Give some thought about how this entry level position helps you build your skills on your path to your ultimate goal and how you'll provide value along the way.
Yeah, I'm early gen-x and I only answer the phone if its a member of my immediate family and even then it's 50/50. Capitalism ruins everything. Need to talk to me? Leave a message and I'll decide if and when to call you back.
Probably wasn't a good suggesting, anyway. Realistically, you need to talk to your parents. You can have an adult conversation with them about your and your partner's wishes. If that 'sours' their attitude, then that is on them. Ultimately, your partner is more important than your parents so protect that relationship, first.
