Just came up with this, but you could ask the interviewee to teach you something programming related that he/she learned recently. That should tell you how well they communicate, can deeply show you their level of experience (and interest), and it doesn't require that they recently revisited their notes from academia. Another option would be to keep notes on programming challenges you hit (and the attempted and final solutions) while doing the job this person is interviewing for and ask the interviewee to walk you through how he/she would go about solving the problem.
