If he stares, and quickly looks away when he looks at you, then yes. If he just stares, and stares, and stares and doesn't even flinch when you look at him, then no.
Yes can lie you and seem interested if he stares at you. Guys don't always have to smile at a girl they like. You will know a guy is interested if he looks or stares at you for more than 4 seconds.
