Honestly, just a guess, you're probably giving off bad interpersonal vibes/people don't really like talking to you. Half of interviewing is just being very personable/being able to talk comfortably with other people. Generally in this space (this space meaning those interested in tech/startups/etc) sometimes people struggle in this area but really shine in tech. I would encourage you to spend some time reflecting on your interpersonal skills.
Some other red-ish flags from your post - you kinda seem like you might struggle just doing exactly what you're asked to do. Bringing up how frequently you quit things for various reasons or finding issues and bringing them up with your superiors' superiors, spoofing numbers to get in touch with very very senior people. Lots of lower-tiered jobs literally just need people to show up and do what they're asked. A part of getting a "first" or "entry level" job is accepting you're there mostly to learn, not to teach/move outside of your lane. The fact that you would even bring up Bill Landreth seems like you might not necessarily see yourself how the rest of the world sees you.
I'm not trying to offend you - I really hope you can line something up soon. I apologize if this feedback seems cold - I think reflecting on things like this can be hard because you have to face things about yourself you may disagree with or not realize. Unfortunately interviewing is such a biased game, you kind of have to play your opponent (meaning, be the person they want, not the person you are).
Happy to chat through any of this stuff if you have questions. Wish you all the best.
