Where does your impression of been a jerk come from? You could not find it in your portfolio much less in this (humbly) post.

Now about the question, without talking about yourself, we see jerks been hired all the time, and not fired, because:

1. they are brilliant and the tradeoff is worth it 2. they are protected by someone

the first one is acceptable (as a boss and as a colleague) if it doesn't trespass some limits. The second is always awful.
