I haven't decided. This is one of the toughest questions I've experienced in recent interviews because I have so many interests, some of them I haven't begun to explore. For now, I enjoy building things that people can use to make their lives easier. Is that vague enough? If I were interviewing me, I'd feel disappointed with the answer, so I always go with something more concrete like, "I'm fascinated by the way we interact with machines, so I've been focusing on UI/UX design." It's technically true, but I haven't planted a flag just yet. I feel the same trepidation you feel when I think about committing to a narrow field like sentiment analysis or augmented reality, for example. Right now I'm learning as much as I can about two different subject areas, testing and WebAssembly.
Maybe your question is even broader, though, and I've had thoughts about that, too. Should I be leveraging my situation to prepare for a career as a lead engineer, or should I focus on PM or business? In that aspect, I am giving myself more time to figure it out. Good luck!
