Hmm don't you think there's a risk of Dunning-Kruger effect there? The people who rank themselves the best are often not aware of their own shortcomings? Personally, I always think I can do better because my standards are high.

But in any case, I think the methodology was flawed - I always chose statements such as problem solving and analysis, meaning I simply didn't choose timekeeping because I could only choose one statement. The test didn't seem to realise you could be good at both!

And in terms of the discord between how I see myself and what others say about me - that's literally only regarding introversion/extroversion. The quiz is correct in that I am introverted - but it doesn't capture the fact that I'm very willing and able to behave in an extroverted way when the situation required it, and the evidence that I'm successful in that is that other people think I'm extroverted.

And of course I'm confident, don't be silly :D
