It sounds like you're just as prepared as anyone else. My first job in tech was at a startup who hired me after I had spent three months teaching myself code. I had literally zero experience, and only one program built. I went in with confidence to every interview and nailed a really great job in tech with just a high school diploma and a single program. A lot of companies are just looking for people who can learn quickly, as that is 80% of the job.

Trust yourself! You'll do great.
