My sister is an ISFP. She works in a bank, and kind of likes it. I think that's mostly because she appreciates the security of an extremely structured job, and she is appreciated by her boss. Who just told her that he is separating from his wife and not to tell anyone. The sleazy bastard.
To be honest, I don't think it's a job she would've chosen straight out of high-school. But she had some tough years doing shitty jobs with no security. I guess working for an extremely structured organization looks a lot like a career. If she'd been male she might have joined the army.
