Guys, is he being polite or interested?

Recently went out and hooked up with a guy. Neither one of us said anything for a week and a half after. I texted him hey stranger how are you type text a week and a half after the hook up. He texts back asking saying what he has been up to and asks how the new job I started is and i reply back saying how it is and he texts back sympathizing in the transition period of job phase. I text him back but send a text that didn't require a response back. I haven’t heard anything since. A week later he watched an Instagram story of mine but we don’t follow each other. Is he interested or just being polite?
