Standardized tests serve a number of roles in public education, very few of which relate to either enhancing or testing a student's ability to get a job.
The main applications relate to checking in on students' progress through the education system relative to their peers. It is also a way to compare the performance of particular groups of students (or schools) relative to others, which is very controversial, but obviously easier than trying to judge the quality of the robots they produce.
By far the greatest advantage of standardized tests over other assessment methods is that they scale beautifully. When you want to ask the question "how are we as a country/state/district doing compared to others", standardized tests provide a reasonably easy-to-interpret, reliable reference point. It's not just about what a test score says about an individual student (which ultimately is very little), but what the test scores indicate in aggregate.
