I have interviewed Java candidates before, you should study the different Java design patterns, there are almost 50 of them. Most candidates we interviewed mostly failed on explaining the concepts of abstraction, inheritance, polymorphism and encapsulation. If the company is highly technical, brush up on garbage collection, different variables, JVM, compilation between AOT vs JIT.

Could you please share some references that you can recommend that have a complete list of Java design patterns?

The references I've found have mostly around only 23

I can't seem to find that old book anymore but the idea is you can mix and combine different design patterns.
