Being able to communicate empathetically with your coworkers is a core competency for technical workers too. There's a difference between an introvert and an asshole.
Asking people to tell their "life story" in a job interview seems like a sign of boundary issues, not empathy. An empathetic person would realize that people come to job interviews expecting to talk about their professional experience, so it isn't the appropriate environment to ask such an invasive question.
You choose what to talk about and what to share. It's open ended to give you the ability to share as much as you're comfortable with. You can tell the story of your career, no need to get any more personal unless you want to.
