In STEM you have to stay on top of current trends, technology changes so fast. This is where curiosity and passion come into play. In every interview you will be tested on things you learned in college up to the technology that came out yesterday.
All of this is not meant to discourage you but to give you a better idea of what it takes to be successful.
All STEM careers will generally require a lifetime of curiosity and learning.
