Various points
"- Terribly written CVs are not unusual I agree, and I have been amazed at some of the poor quality people submit, but I've not noticed any connection to the particular university they attended. I think that is just snobbism to be honest."
That is so so differetn from my experience and I get several CVs a week. There is a direct correlation to poor comp, bad GCSEs, terrible middlesex poly type institution and CV quality, compared with I went to a good school, got AAA in my A level sand 2/1 from Bristol CV. I think I have never seen a well written CV from someone in the first category and virtually always do from the second. The second know where to put their apostrophes and things like that.
I was also asked:
"What in your opinion is the biggest draw back of a good state school education?"
Most people go to state schools and lots of people who do do absolutely fine. It's not a question of draw backs particularly and it depends where in the country you live. May be in state schools (and my children's father has taught in both sectors so it's not as if I'm completely ignorant of the state sector) your peers can be less ambitious and most of us have fairly mediocre children rather than thsoe who are happy to be the nerd, studious one who stands out from all the others and can cope with being teased. Most children are just in the middle somewhere. So if 100% of your class go to good universities and get over 90% A or A* in GCSE like at say North London C where my daughter went, then you're likely to follow that herd and do what your peers do. If most are going to leave school at 16 and go on the dole then you probably follow the majority.
Secondly perhaps accent, connections, class isn't helped even in our better state grammar schools, not that I think ever a connection from my school has led to any work. Perhaps your friends are more likely to take you on skiing holidays if you're in the private sector. But my children didn't go to school with particularly rich peers so I didn't really notice that effect particularly.
