Spot on Exmil-person. All interview and selection processes I have taken part in, for both aviation and non-aviation fields, has been competency based. It exists in all walks of life so get used to it! I am sure they will be some fresh school leavers who really have gone the extra mile to gain the required skills through extra-curricular activities, so I would not read it as entirely biased against the proverbial 18 year-old. You are 16 years old so have the time to work on any blanks in your CV.
