Woof etc, I don't think it's fair to point fingers at the testing officer in a case like this. The perception of an individual's attitude varies greatly from one person to the next and even in cases where a bad attitude has been identified it's still quite difficult to objectively use that as the pass/fail item. All technical aspects of flight testing are known quantities, you either know what you're doing or not. Tick those boxes. However, the accurate assessment of someone's psychological attributes is widely acknowledged as being one of the most seriously deficient elements in modern aviation. A look at some of the social hand grenades climbing into cockpits every day will testify to that. My point is, there just isn't enough information and knowledge available today to effectively implement a filtering system that will be satisfactory to all.
