One thing that makes younger engineers stand out is having mastery over a language. This will be evident to most interviewers and will be a big help in day-to-day tasks. It also opens the door to having a good mental model for becoming very proficient in other languages, which you will definitely need to be down the line.
Getting good at various patterns that are native to the language, understanding how to profile/use debuggers, understanding memory and CPU performance, the ecosystem, memorizing the standard library, etc are all part of this learning.
