What is That Stuff Above the Peanut Characters Heads?

Today I had a job interview. It wasn't a good one. I tend to think all of them suck, and that I will fail. I don't understand why I keep trying some of the time, although I don't have many interviews; this was probably the third this year. It seems that whenever I am interviewed, the CIO or Director seems to think that being an asshole is the only way to get a sense of what type of person you are dealing with. I can see that logic. I think you can see it by being nice as well. If someone has a character flaw or has a hard time explaining themselves, that will come up naturally in the interview. At the beginning of every interview, I try to forget asking myself questions and instead focus on being centered and being true to myself. And I find that I betray myself once a situation comes up. Which leads me to being true to myself. Once this happens, I tend to spiral into self-attack - how could I have bent on my beliefs and convictions? Well, I did. No point in dwelling on it now, except to learn from it. If only I didn't dwell on it. I'm dwelling on it, and building a basement and a panic room below that. And I feel like that is the biggest obstacle to getting a job. What is my greatest weakness? Panicking and freaking out when someone pressures me to bend and my natural inclination to accommodate gets the better of me. Someday I will be able to move on. Someday my greatest weakness will be something else.
