Re the personality tests.
As far as I can tell, it's less about your implied personality and more about the consistancy of your answers.
Even though the questions are all worded differently, they are all asking about the same 4 or 5 (or whatever) personality traits. So don't answer one question saying that your decision making is slightly better than team-work (for example) then say different in the next one.
Just my thoughts. Good luck to you all.
