Convention seldom works for me because I am not well prepared for it, unfortunately. If you can’t win at one game, you have to play a different game that you can win. The trick is to get someone else to play with you.
The most effective way to lead a person across a stream is not to call him over. It is to go over to where he is, see what he sees, and walk with him to the place where you have already been. (yeah, I watched “Kung Fu” way too much back in the seventies). But seriously, try to put yourself in the person who is hiring for a specific job’s shoes and try to figure out what about you can make you a person of interest and what does not matter. Then try to figure out a format to get that across with the least amount of background noise.
