Ruthless,
Road sweeper eh ????? might actually be a promotion from driving my 757 / 767 !!!!!
I too have been FORCED to interview prospective candidates at my company. This is a job I hate and would never volunteer for.
If you are what you say you are, then you would know that these exams really mean very little and are merely "hoops" that need to be jumped through in order to gain your licence.
How much of the information you had to learn for your exams have you actually remembered and are using on a daily basis ???? not much I would guess. Could you pass the exams today?? I would guess not. Does that make you a worse pilot??? Well, only you can answer that.
Personality is basically what counts in the interview situation.
Hope I never have to interview you !!!
