I did get feedback, they phoned me. Say said they liked me and that although I did well in the tests I balls up my interview. She also said that I lacked any experience in the maintenance/engineering field.
I was told to get some experience and apply again as they recruit for apprentices yearly.
I have no idea where to get experience though. I've had so many job offers turned down lately I'm thinking about just joining the army and getting out of here.
