You tried but did you really try . . . in a way that exceeded the competition? Perhaps not. Did you work every summer at a firm or elsewhere? The students at my law school alternated 10-week rotations between classroom and working in a legal setting. They did not get summers off. This was required of all students; by the time they graduated every student had worked in four different (almost always) paid positions. They were well poised for employment when they graduated. In fact, most of them went to work for one of their previous 10-week employers.
It goes without saying that the plum jobs are for top graduates at first tier schools. If that is not you then, no, you never really had a chance. Similarly, those plum jobs are often reserved for people with connections (family, legacy, friend of X). Again, if that is not you, then you never really had a chance, but admission officers were not lying when they pointed to high starting salaries for new law students landing those plum jobs. The people who secured those jobs are doing well and there was a time, in the dot-com era for example, when such jobs were plentiful even for students at second tier schools.
