Maybe the process is fair and a good indicator of suitability, maybe I am indeed not up to the job and have been rightly eliminated from selection and I agree my analogy was a poor one! I also stated quite clearly that I did not know if I was a borderline case or not, the point I was making was that in my opinion potentially good and motivated applicants are precluded from interview prematurely. For the record I also take on board that the HR staff are mostly helpful. Rant over.
Good luck in your application if you are not already through Louby.
