If he/she been able to get a job doing dev work, and that's the career he/she wants, what more is he/she going to learn that he/she could not learn him/herself later if they wanted (online or books). As a hiring manager I'd usually check out where the person has worked before if they have already started working. If it's the first job, yes the education matters because there's nothing else to go on. If it can be managed they may as well complete it, especially if there's any chance they want to do a degree.
