As someone who was also home schooled and had problems with social interactions in my early twenties the best advice I can give is join several clubs that does things in person.
You MUST learn how to make friends, how to not upset people, how to be comfortable in social situations and empathy.
To do this I would recommend that you force yourself into social situations regularly. Afterwards spend some time thinking about how the interaction went, especially from the other persons viewpoint, practice empathizing (it is a skill that can be learned and will make you a better more considerate person).
So join several clubs that meets and does something in person. You should have two scheduled social events every week.
Try your best to be aware of peoples feelings and groups social structure so that you can try to not trample all over either.
Going straight to upper management as you described is generally not well accepted and most definitely upsets middle management (the people who would actually hire you).
Basically, realize that the problem is who you are and that you need to become someone else to succeed. Changing your own personality is one of the hardest things one can do, so expect it to take a few years.
