Sorry, I'm out with both. They lied. Full stop. What else will he/she lie about next? You can't walk into an interview and lie about your skills and not be outed - you can walk into an interview, be candid about your lack of skills in one particular area but highlight your strengths and willingness to learn new skills. I'm glad this programmer worked out for you, but I'd be careful about trusting too readily in the future.
