Java Mock Interview | Interview Questions for Senior Java Developers

This chapter of the Turing Mock Interview series takes an in-depth look at what a technical interview for Java would look like. Watch the video above to understand core Java concepts and learn more about the questions that might appear in a Java test and interview.

Turing connects exceptionally talented software developers to remote engineering jobs at Silicon Valley and US-based companies. 200+ companies, including those backed by Google Ventures, Andreessen Horowitz, Founders Fund, Kleiner Perkins, and Bloomberg, have successfully hired Turing developers.

- Turing offers a wide range of long-term, full-time remote jobs for Full Stack, Front-End, Back-End, Mobile, DevOps, and AI/ML developers.
- Turing remote developers enjoy higher pay than local standards in most countries, a healthy work-life balance, a strong sense of community, and rapid career growth.

Turing is backed by well-known investors like WestBridge Capital, Foundation Capital, Facebook’s first CTO (Adam D’Angelo), executives from Google, Facebook, Amazon, Twitter, and Founders Fund (investors in Facebook, Tesla, Asana, etc.), among others. The company is led by serial AI entrepreneurs Jonathan Siddharth and Vijay Krishnan, whose previous firm leveraged remote talent and was successfully acquired.

The company was founded in 2018 and is headquartered in Palo Alto, California.

looks like fresher interview to me. Interviewer nowdays usually jump to collection, stream api, java 8 other features, concurrency and goes to framework like spring and microservices and design pattern

[MMaSSoDJ]

Applets and RMI questions? Really??? In 2023??? OMG...

[debasishchakraborty]

To my understanding in Java we can override the finalize() method in the child class as this method is originally a protected method from Object class and hence it can be accessed by any class(by default all class extends Object class in Java) and then further if any class being extended by another class in some customization. Normally there can be a case we may have created certain object in our application which may be accessing certain resources and we may need to free up for memory reclamation. Hence I believe "finalize()" method can be overriden.

[AbbeyLingord]

Wow. Reading answers on interview. If I only thought of it earlier...

[melvinkimathi]

Interesting. I would like to see the Java code challenge. Well done Jose.

[sumant]

Explain Java’s memory management. How do garbage collection and memory allocation work?

About Override finalize method in a class extending from Object... you can @Override public void finalize() but you shouldn't

[sumant]

2. How does Java’s concurrency model differ from that of other programming languages like Python or C++?

[alanbal]

As some high voted comment already mentioned, we can override finalize. It'd be good to clarify that this is not recommended and instead we should stick to defining clean up logic in the finally section of the try or define clean up behavior by implementing the Closeable/ AutoCloseable interface and use a try with resources clause.

[konstantinvolkov]

Yes we can override finalize because we need to put our logic into it. leave some log or release file resource and etc.
))) Guys correct me if it's wrong please )))

[yoyocswpg]

I have not heard of Applets and RMI mentioned anywhere except in college 😂 and the guy answered them all 😅

[andresfelipemenesespaz]

Jose i was review this interview, and about your question of override finilize() method, is not a good practice, the main reason that it can not be relied upon to perform cleanup tasks in a timely manner or maybe or even guarantee that it will execute due the upredictable nature of the GC. some times using finalize methon can lead to permance issues and errors .

[renatomdemello]

I wanna see the Java code challenge! Great video, tks!!

[user]

You blow my mind who use Applet and RMI

[mmmm-wmci]

Will this help in clearing turing java assessment

[владимирсенцов-рю]

I have been working as Java developer since 2016. But I have never seen applets and rmi in my projects.

[vsekvsek]

Ten yrs ago i got questions like thai. This last yr it was all spring type stuff. Almost no java questions for java dev jobs. So weird

[javieralbertoramirezramos]

Great Video Interview I really like the way you conduct the interview. I would like to see the Java code challenge.

[cheikhsadbouh]

Is applet still used in the java ecosystem ?

[AidarKhaibulov]

Really? That was senior interview in 23?? Just an intern questions about java core, some unused stuff and interviewer hasnt even asked anything about databases, system design et c.
