The first question in the Cambridge survey is "I am good at predicting how someone will feel." What a stupid, meaningless survey. This isn't diagnosing me at all: I know exactly what answer to the above question will lead to which result, so the results are 100% determined by my choices rather than any diagnostic system.

It's even more stupid when you realize that even if I have great awareness of the rate at which I can predict how someone else will feel, it also requires me to have awareness of how my ability in this area compares with everyone else in order to choose between the gradations in answers between "strong/slightly disagree/agree". The first question summarizes the whole point of the survey, and leaves all the diagnostic work up to the test taker's own abilities! I find most tests to be like this. Complete farces.

A meaningful test is expensive: An expert would observe me as I interact with others, ideally in a controlled environment that's the same as other test takers.
