However, how can we say for sure that employers don't AT ALL look at the university factor? Employers are only human. And as humans, many of us are attracted to the more popular option as seen through certain materialistic goods, for some, only because of the status symbol.
So why can't employers make decisions similar to this? In this case, picking the student from the more socially popular university based on academic competitiveness and reputation. Especially when they are faced with the dilemma of choosing between two students, one from a more prestigious university, but both have the same grades and achievements. There is MORE reason to choose the student from the more prestigious university. Its all in their discretion after all right?
Basically, what I'm trying to say is that we cannot make definite statements on who law firms will employ based on a person's tertiary study. we don't know how employers think 100%. We can only speculate by thinking what is more attractive, as a human being, who would people generally pick.
Nonetheless, wherever you are, if you try your best, stand out from the crowd both academically and in the extra curricular fields, there is no real reason you cannot be competitive enough for a job. Good luck!
