Snakedoctor, I think this whole thread says a lot more about Hacker News and its penchant for armchair psychology and condescension than it does about you and your future prospects.
There's a few helpful posts here... take what you can and go out and seize the day! I am routing for you.
It seems that a lot of people replying here never understood the phrase "don't just a book by its cover". So many people are opining about OPs character in definite, and it's just unpleasant to witness. Sure, the whole calling VPs directly thing is a bad idea, and definitely inappropriate, but I can understand someone feeling like they're doing the right thing to advocate for an issue they see to be impactful. I wish I could CC this to all the people postulating OPs universal lack of empathy. I agree that he could benefit from therapy, because honestly we all can benefit from therapy; but all the posts implying he needs to be medicated or psychoanalyzed are reprehensible. I see someone who is upset with where they are, so they wrote a post conveying that in a slightly conceited way, yet so many talented minds in the field of tech are coming to this post to say that he has delusions of grandeur.
He is the book, and this post along with the comments he's making are the cover. You can give advice on what's presented without insulting his character.
My take is you seem to have an inflated sense of your abilities. I've interviewed people who share this trait and it's a turn off unless they have a portfolio of work to back it up.
Perhaps try taking a more humble approach. Ask lots of questions as to what/where they need help. If they align with your experience then share concrete examples of how you've helped others in those same situations. If you haven't, make note of the challenges and see if you can identify patterns across interviews. This would provide hints as to what skill-building you could focus on in the interim.
Good luck!
