I have to agree with grasshopper.  The email (although meant to be a wake up call for the individual) came across as insulting.  The author did a great job in protecting his company and their interests by providing a fairly thorough interview and subsequent due diligence. That was his responsibility.  What was ALSO his responsibility was to NOT make the individual feel lesser of an individual because of his knowledge base and that is the risk the email presented.  Who knows what the individual was like.  Would this be the one "life occurrence" that had lasting dertimental effects.  One would think hopefully not but if there is one thing I have learned in my life thus far, is that just when you think you know something, poof.   I can understand the frustration of the author but the leaders must lead.  Now what the hell are these BOOKMARK LOOKUPS lol
