As a fresh graduate in Hong Kong, majoring in information engineering. I still don't know how to explain what my major related to... And don't even expect me to know any node , react , angular, docker, etc...

Information engineering is not related to data science?

Welcome to devRant! What sort of jobs are you applying for? How are you leads? Maybe we can suggest techniques.

I have learned stuffs related to System Signals, Fourier Series, Microprocessor, Operating System, Programming Pattern, Network Programming, Scalability Application, Cyber Security in Network Programming...

So many things in different fields, and end up only have basic concept of different things...

Exactly the reason why I put mine on hiatus and went to gain experience at companies, learning the expected tools and frameworks outside the office

At the very least, you've got a solid foundation
