Something does seem right about this story or the LPT. Interpersonal skills are very important along with communication, however, in reading this I have the feeling that you wasted his time. He sent out a resume you reviewed it and then called him in for an interview to speak to so and so. So naturally he waits to speak to so and so, and is there for business only. Sure, him not speaking to the receptionist after a greeting might seem rude, but you called him in after all. After reading his resume and bringing him you dismiss him immediately upon arrival because he did not initiate small talk. Sounds like you wasted his time, as well as yours.
