It's been an absolute mare for around 10 years of so. We take on 3 graduates / year and none of our 2017 intake lasted past Christmas. These are the ones who have got through the interviewing process & aptitude tests!
So many with text book answers who crumble when faced with reality. We're taking a different approach this year and have offered apprenticeships to students with degrees, based on the intent to add practical knowledge to the theory gained at University.
