Perspective people. It was a minor mistake, not worth mentioning in the context of a 12 week process for a $100 000 job.
Do you think those corporations like Google, Microsoft, Apple, IBM, HP, Oracle, Yahoo - all those that have left Amstrad in the dust and make Viglen look like a yo-yo dealership - employ anyone who gives a flying flippancy about greeting strangers by their first names? Nope, and that's why they got where they're at. Never let an irrelevant formality get in the way of adding value to the company (in this case, a talented job candidate).
Steve Jobs, Bill Gates, Larry Ellison and people like that are renowned for not giving a crap about formal politeness. If those are the sort of people Sugar wants to find in the next generation, he can't afford to employ stuffy interviewers. Of course, we know that;'s not really what Sugar wants so the whole thing is hypocritical nonsense.
