IS THIS GUY INTERESTED?

so i saw this bunch of guys at the mall the other day, i caught one of them checking me out. He came over and said hi to me and started flirting with me...i kinda ignored him at first but then later on i bumped into them again...his friends started to tease him about it...and they were all staring at me...but he didn't get my number or anything...so is he interested?
