I don't employ myself however the company I work for is rather picky about where people studied. I have found when training new employees that quite a few highly qualified new hires didn't know which end of a screwdriver did what, they just weren't interested in installing complex oilfield equipment. This was mandatory for their progression though. I also had a new start that didn't speak to me for about 2 months as I was one of the youngest field guys we had at our base. They only started speaking to me when they were informed that although one of the youngest I held the most senior position.
My father on the other hand does employ. Well actually he has people that employ for him. He can have a say in hiring as at the end of the day it's his company. He generally employs people that have served apprenticeships and those that don't flit from employer to employer. His sparkys obviously have to have the correct qualifications coming from apprenticeships but his office based Engineers have all graduated from workshops rather than universities.
He said he's wasted time, money and energy on graduates in the past and generally it's not worth it to him. He'd rather give someone a chance in a shift that just hung up their coveralls.
For the record he has no school qualifications, didn't even sit any exams. Half his teachers probably didn't know his name as he was never there. Hard work and good mentoring has made him and his business the success it is today.
At the end of the day, it's what you do in your job that counts. Getting the all important foot in the door can be hard but once in it doesn't matter if you graduated from the inner city school of chav with an honours degree in being a c*ck or with a PhD from Cambridge. If you work hard you WILL be noticed.
