In a way, competence is for me, and friendliness is for others. Here's what I mean:
I need competence to get through the day without getting killed, and doing my work to my own satisfaction, even in the absence of anybody else watching. I have hobbies where lack of competence would be instantly obvious, such as being a jazz musician and manufacturing a humble but useful product.
Naturally I also need friendliness to get through the day in any social setting, and to do my work to the satisfaction of others. Since I'm moderately extraverted, this is valuable to me. My job is in an area where neither my boss nor my colleagues understand what I do. So, I need to be trusted.
But I can't imagine doing a job for very long, where friendliness can make up for lack of competence.
