A job related all or one of these related fields, IT security, Network security (that's almost the same as IT security), Computer security. I also have no job experience (as in actual job time), but I do have expertise experience related to projects that I have and am doing in college. I am graduating in May with my masters.
So, having no experience, the message you need to get across is 'I can learn'. Believe me when I say right now, you don't know enough to be productive in IT. Based on that, don't try to fluff yourself by saying you do, or that you can do things already. Make them understand that you can spin up on new knowledge quickly. Talk about how you self-taught xyz in x days or weeks, talk about how you worked ahead of the class on abc content or projects because you found it easy to understand.
Regarding the actual interviews, practice pretending to be human. If you're an introvert (you have 3 friends, you're an introvert), you understand what that means. You'll never come across as affable by acting natural, because natural for an introvert isn't affable by extrovert's terms. Just act like you're not a weirdie, someone who collects stuff, someone who'll put people off. Talk about quirky but reasonable talents or hobbies you have, like blacksmithing or running an amateur tree nursery or online gaming or something. Accuracy isn't super important, just make sure you have some backing knowledge so you don't look like a liar or an idiot.
