Can I tell if a man likes me by the eye contact?

I like a guy who works in the adjacent office but am shy.. yesterday we had to walk past eachother and I noticed when we said good morning he kept staring even when I stopped looking.

I attempted to talk to him a little later at the coffee stand but he just kept it professional though, so I’m not sure. I can’t completely discount him liking me because if I like someone it will seem the complete opposite but should I judge off of that eye contact encounter? Do men typically keep looking after passing a woman?
