Does it matter if I went to a university ranked lower than 100 for engineering. Would it affect my job prospects
One would hope so, otherwise why are so many students fighting tooth-and-nail to get into top-tier universities?
Engineering is a very broad term. Chemical engineering? Software Engineering? Mechanical Engineering? Or are we talking about General Engineering?
I can see that you've posted in the University of Manchester and University of Central Lancashire forums before. Manchester is rated highly for engineering, and UCLan is probably ranked around the 100-mark - so let's compare the graduate outcomes for students from these institutions. I'll use Mechanical Engineering BEng (Hons) for the comparison.
Six months after graduating, 67% of Manchester graduates are "employed in a role where degree was essential or beneficial", with 52% being engineering professionals. By contrast, six months after graduating, 85% of UCLan graduates are "employed in a role where degree was essential or beneficial", with 58% being engineering professionals. Hmmm, that's odd.
What about income? 1 year, 3 years and 5 years after graduating, those graduating from Manchester are earning on average, £27k, £33k and £38k respectively. The same numbers for those graduating from UCLan are £25k, £32k and £34k.
So, it really doesn't have the sort of impact you might expect. The source of the data above is The Uni Guide, here and here.
