ok so somehow I managed to get an interview for a graphic design position at a company in the oil industry, however I actually know absolutely nothing about graphic design beyond some stupid logos and posters I made for my friends bands and some other miscellaneous bullshit
they honestly seem to think I know what I'm doing so far but nobody has really questioned me because I think everyone I've talked to is old and knows even less about graphic design than me
what the fuck do I do
If you get the job spend all of your free time practicing and watching videos on how to design. Play ignorance if anyone asks.
Most of the work you will do will not be very technical so you can get by with what you know right now. I believe in you OP
What this anon said.
Fake it till you make it but you better hunker down and fucking learn as much as you can if you want to keep your job. Buy a subscription to Lynda if you have to, I don't care. Read books, watch documentaries, develop an eye for design all around you. Everything is designed by somebody, there are always lessons to be learned. Just keep studying, keep practicing. Learn your fundamentals and learn the basics of Photoshop, Illustrator, and InDesign, then learn how to be awesome with them.
You can do this, anon. It will be a lot of work but you can do this. You can carve out your own career path. The fact that you care enough to ask for advice and help here shows a strong foundation. You can do this.
That's how I was hired to make the illustrations for an educational book to be printed in the thousands every next ten years or so as a standard in some higher educations in my country.
Here's what I did: I opened Illustrator, clicked the pen icon on the left and started drawing shapes, sometimes over photos in the public domain. When I encountered problems, I googled for a solution.
No one questioned me. No one had any inquiries about my competence or experience.
The only advice I can give you, if you'll even have to concern yourself with printing and such, is to learn about color management and color profiles before you start.
Another solution besides actually learning shit is to just hire a freelancer to do your work and give him 10%.
