OK Mike, I'll humour you...
I said earlier that each line of questioning should probe, to determine depth of understanding; for example:
- please tell me about V1
- what might happen to V1 on a wet runway?
- what is the relationship between VEF and V1?
- is VEF determined at the design stage or defined during flight test?
I'd hope any competent candidate would give a reasonable response to the first 'question'; very few indeed will be able to answer the last one. Rather than predetermined streams of questions, it's better to pick at the answer to the first question in a set, as the limit of knowledge is more rapidly determined.
This method means we don't just find out whether people know the answer, but whether they know the topic. 'Please tell me about...' is much more effective than a WWWWW question, too, and allows people to identify their own limits.
We tell candidates that they will be asked questions to which they don't know the answer.
The cardinal sin, of course, is bull####ting...
