Fascinating. Can you now please tell us:

(1) the success rate of candidates who can answer these questions
correctly in getting past the first interview?

(2) the success rate as measured by employers who administer these
questions as part of their recruitment process? measured in terms of
satisfaction with the employee?

(3) the perceived relevance of the quetions as measured by employers ...
ditto?

(4) the % accuracy of the answers provided to these questions as judged
by independent experts?

Until you provide this kind of data, this is just meaningless spam. Note
that I am not claiming any necessary correlation between (1), (2), (3),
and (4).

From a quick scan of the questions and answers I would say you are
contributing to the problem rather than solving it. The answers in
general are meaningless drivel which would give me, as an interviewer,
no confidence that the subject understood the topic. See e.g. the
mutually circular answers to 'what is a class?' 'what is an object?'
'what is the difference between a class and an object?'
