To be honest such scenario is not so hard to imagine. When I think of my studies, it was probably some introduction to Java, we learned how to use javac during first lesson, but never used it since, because we just clicked button in IDE. Someone who missed the lesson, might never noticed he misses basics. With advanced build systems in some companies, someone who arrives from scripting language, is shown build system and told to look up the syntax might not ever realize the gap in his knowledge and at the same time might even be productive part of the team.
