You have to read between the lines on job applications. What they really mean is, "is this person going work well with everyone else here at this particular company?"
There's nothing that just because you have SA means that you won't be able to sit on committees and report abot your work. If it's in customer service, you can guaranteed outgoing is important. I think what most employers want is some who is efficient and just friendly. You don't have to be everyone's best friend

. I know some real jerks who hang on to their jobs!
Also keep in mind that you could tailor your applications to your strengths ("Works extremely with minimal supervision") and ("Extremely Self Motivated") and ("Takes Direction well and accomplishes goals by deadline with minimal supervision.").
There are also ways to work on teams and be quiet. you just try to avoid speaking until someone asks you a speciifc question

. And if you have to give a presenation, you pretend everyone is in their underwear, or take a half a xanax a few minutes beforehand
