Traditionally, you’d expect technology companies to have a pipeline to identify and cultivate junior talent (an apprenticeship). Instead, they rather pass the buck to leetcode and bootcamps. Quality engineers are expensive, so you have to operate your bootcamp similar to the traditional higher education TA model (low paid teaching the paying). Are ISAs predatory? Hard to say, depending on what you think of equity, free will, determinism, and “someone has to take the chance and pay for this.”
