So this is likely speculation….. in fact I know someone who got picked up for Intel that got 9s and an 8.
I doubt the 8 was the OIC as the board sees that and it is going to be an issue, a 9 happens sometimes but often accompanied by comments on the sheet that are glowing.
I can tell you that in over 3 years not 1 person who went for DCO via my office that had an OIC interview less than 10 was picked up, my lead processor who worked at 3 different recruiting districts over 10 year said the same thing which is why we were paying attention.
It was when application numbers started decreasing that you started seeing an occasional 9 OIC score get picked up.
Next Wed I will be at a career event where I know the recruiters will be there I can ask they think now, but when this came up 18 months ago and I asked the last guy he said 10's are competitive anything else isn't.
