1- When they are asked a question they don't know the answer to, and they respond "I didn't learn that, we don't use that at work, only in school" instead of "I don't know"

2- Most hiring managers are actually more interested in soft skills, professionalism and attitude than they are technical skills. Even if they are giving you a technical interview, they are evaluating soft skills more (the way you answer, how you act when you don't know the answer, etc.)

Did you have hearing protections during those situations? If not, did you notice long-term effects of noise exposure (hearing loss, Tinnitus) ?

There are a ton, here's one I can think of:

"What are the most important attributes a candidate needs to have for this position? What do you value the most?"

Maybe also:

"What worries you the most about me for this position?"

Then you can answer why that you're not that bad at that thing.

In the companies I work for, they have a minimum standard for communication/attitude. They would refuse a 100x coder if those things were subpar. The reason is the coder will need to interact with customers and the company has to protect its reputation.

Honestly, get some side projects going. You can make a simple, somewhat useful side-project in a couple days of work. If you spend a week or two making a few of those, and you get a better job as a result than if you didn't, your future self might end up 2x as wealthy due to those few weeks you spent. Why? Career growth compounds, especially early on, getting a good early start accelerates your career.
