It consisted of a telephonic, basic of java : overriding, overloading rules, design patterns, sort may on key and values. Java 8 Date Time API, streams, lambda expressions. Then a face to face with the Technical Manager : we had a general discussion about the job role. He asked me some questions on Executor framework, why we have it. Spring scenario oabout what if a singeltion scope bean uses a prototype scope bean. The was a design assignment given to solve in office : Design a Library.
