If you are preparing for Java developer interviews and wondering how to begin preparing for Java interviews, this blog would offer you informative tips! Java interviews are slightly different from traditional tech interviews conducted by tech giants and product-based companies like Google, Microsoft, Facebook, and Amazon. Java interviews have questions related to Algorithms, strings, linked lists, or arrays. By considering Java bootcamp, one can easily manage to clear Java interview sessions even if one is not an expert. 

Another essential component of Java interview sessions is the questions based on Java programming language and JDK API. As it is popularly known as an Object-oriented programming language, chances are you would find numerous OOP questions. As Java is mainly used as an application programming language, the focus can be aligned with interview questions targeted at API, design patterns, and java concepts. Additionally, Java interviews change depending on candidate’s experience. For instance, if you are a junior developer with experience between 1 to 4 years, chances are you would witness more questions on topics like API, data structure, algorithms, and fundamentals.

 

Senior developers may find questions on concurrent programming, JVM internals, Java concurrency, GC tuning, and Java performance. Additionally, if you are preparing for the Java EE interview, it is entirely a different game with questions focused on Java concepts like 6Spring, Hibernate, JSF, and several others.

Now, if you are preparing for any of this area, consider a Java bootcamps are your go-to place.

Now considering the important topics you must brush up for core Java interviews.

For those with 4 to 5 years experience, questions related to Garbage collection, testing, and design patterns. Another area that decides which topic you would prepare for interviews is the job profile you plan to enroll for. 

For instance, if you are going to work on core Java multithreading-based application topics such as multithreading, concurrency, Java collections, Enum, GC Algorithms, JVM internals, and Generics.
