Over the years I have been a panelist in many of the interviews for Java Developers. I have previously written a post titled Top 7 tips for succeeding in a technical interview for software engineers which covers few of the general guidelines. In this post I will share a mind map containing general topics covered in a Java developer interview. I have prepared this as a general reference for myself to remember the pointers and to keep a common standard across the multiple interviews.
XMind gives a nice listing of the map. You can find the map here. Here is Image which you can download and use.
Finally here is a old fashioned tabbed content list which is easier to copy paste.
Interface - Abstract Class
IS-A vs HAS-A Relationships
Aggregation vs Composition
Method overloading vs Method Overloading
Compile time vs Runtime
Shallow copy vs Deep Copy
Map, List and Set
Equals - Hashcode
Legacy - Synchronized Classes
Stack vs Heap Memory
JRE, JVM, JDK
Checked Vs Unchecked Exceptions
Exception handling best practices
try, catch, finally, throw, throws
String - StringBuffer - String Builder
SAX Based & DOM Based
JAXB - Java API for XML Binding
Packaging the Applications
SOAP, WSDL Webservices basics
Contract first vs
RESTful and its advantages
This is a work in progress and I hope to refine it further. Let me know if you have any comments.
