It appears that you're excelling in one aspect of the evaluation but failing in another. There's a reason WHY they're not following up. If he failed some other part of their interprocess -- that's fine, they can send a polite and professional rejection letter. Even a soulless form letter will do. But to not follow up in any way with the candidate, after that? Unless the candidate vomits in the interviewer's lap, or something similar -- that's just pure rudeness, on the company's part.
