Entry-level Java dev interview in ~1 week. what should I drill? (CS/Math background, mostly Python experience)

[u/Tasty-Builder-8401]

Hey all. I have a technical interview for an entry-level Java role coming up in about a week, and I want to use the time wisely.

Background: CS + Math degree, so I'm solid on data structures/algorithms and general logic, but almost all my hands-on coding has been in Python. I've been working through Java on Coursera and just finished the core OOP stuff (inheritance, polymorphism, abstract classes vs interfaces, exceptions, static/final). I'm comfortable with the syntax now but haven't done timed coding problems or "explain this concept out loud" style prep in Java specifically.

For people who've done entry-level Java interviews recently:

1. What actually got asked? Was it mostly OOP theory questions, LeetCode-style DSA in Java, or a mix?
2. Anything Java-specific that trips people coming from Python (I'm guessing things like static typing gotchas, collections framework quirks, == vs .equals())?
3. What would you drill hardest in a single week if you only had a few hours a day? Conceptual Q&A, coding problems, or both?

Not expecting senior-level stuff, want to walk in solid on fundamentals and not freeze up writing Java under pressure. Any resources, question banks, or "wish I'd known" tips appreciated!

Please ensure that:

• Your code is properly formatted as code block - see the sidebar (About on mobile) for instructions
• You include any and all error messages in full - best also formatted as code block
• You ask clear questions
• You demonstrate effort in solving your question/problem - plain posting your assignments is forbidden (and such posts will be removed) as is asking for or giving solutions.

If any of the above points is not met, your post can and will be removed without further warning.

Code is to be formatted as code block (old reddit/markdown editor: empty line before the code, each code line indented by 4 spaces, new reddit: https://i.imgur.com/EJ7tqek.png) or linked via an external code hoster, like pastebin.com, github gist, github, bitbucket, gitlab, etc.

Please, do not use triple backticks (```) as they will only render properly on new reddit, not on old reddit.

Code blocks look like this:

public class HelloWorld {

    public static void main(String[] args) {
        System.out.println("Hello World!");
    }
}

You can revise Java 8 features, multithreading etc.
