I'm not understanding how Java---famed in Enterprise applications, and Javascript---famed in frontend development and now SPAs is going to put anyone on the bottom rung of the tech workforce in general. Ofcourse once you graduate whether it be a bachelors degree or a boot camp, you're at the bottom rung by default. Yet what's unexpected about new graduates doing entry level work?
