Agree with this, last place I had an IIP guy in, I didn't get selected from our area yet my techy who had just been on a course did.... I dropped a hint in the staffroom and in hearing of the IIP man (as i was in a bitter mood) that it was a fix and the IIP man did say he knows it is and it is in every establishment, however they leave it up to the establishment to chose the "random" selection of staff for interview.
