I know exactly what you mean and this is pretty much how I operate too. I don't like following any strict protocol, I just like being spontaneous.
It seems like people in creative industries are more accommodating of this, which is why I got surprised that my art teacher was saying all this lol.
But I can understand the employer's concerns too. If they get a candidate who is just a rebel and deliberately going out of their way to not listen to the boss, then its a concern for the employer because their company's productivity is at stake. But as long as they're honest and diligent, I think they should overlook silly stuff like being socially awkward or not moving the chair properly.
Ok cool. I think in a job interview, I would tend to act like a robot, and make absolutely no effort to try to be creative or stand out, just kinda brag about what I (didn't actually) accomplish. My problem is, if i got the job, I would start to be inefficient or screw up or not take anything seriously. Even with a lot of potential, generally just underachieve. I am working from home now but I can work from midnight to 8AM to get everything done so I can work on my own schedule. I can sleep from 2PM to 4Pm and then rush to ship everything out before the 5PM cutoff at the post office. I could also work from 3Pm to like 9PM and then sometimes take the next day off and sleep all day. Any 9-5 job I would consistently be 20 minutes late and take too long for lunch, I have to work on my own schedule.
On a date, my natural tendency is to just be a goofball. Even as an older guy now, I feel like a teenager in many ways, i take nothing seriously and would rather say shocking and offensive things to break the tension than just ask the standard questions or say the standard things. Most women have no clue if i am serious, a wacko, a goofball or what my agenda is. All it really is is that I don't take anything seriously. I could carry on a sarcastic ridiculous conversation for 3 hours and never come back down to earth. Most people are not like that. From what I observe at games I go to or restaurants I very rarely go to, (I never eat out, only order or get food to go)... Most older guys who are married or in a serious relationship, tend to not really talk much, to their wives or girlfriends. I just see a lot of silence, where often the man is the provider, although you see that less and less in 2020, but the guy is just kinda the worker bee, who sits and provides, maybe asks a few questions, maybe makes one remark every 40 minutes, but not ruffling anyone's feathers, just generic talk and questions but mostly dignified silence. The wife or girlfriend might be talking to her friend or talking on the phone or texting. My point is people don't want people like me around or know what to do with them. I would say or do inappropriate things for shock value. Kinda like I am doing a prank show like Jackass or Impractical Jokers.
