Submitted Sales Tax solution and got the feedback that they liked it and called for f2f rounds. First Interview (1 interviewer) -Extended the exercise and code with more scenarios. Observe your code writing approach. -Questions on design patterns and oops concepts. -Current projects, problems and solutions you provided. The main intend is to know technical competency and depth. I got the feedback by interviewer it went well. He told me that there are no Java projects in Gurgaon centre, which was surprising because I could not understand the whole objective behind examination and calling me for process at first. But I kept positive attitude. Second round (2 interviewer): -ORM Levels? -Generics is runtime or compiletime? -Why use stateless or stateful EJB? -What will the snippet when there are no container managed transactions in JEE. -Parse an entity+entity manager+update into plain jdbc connection+statement+execute. Basically write your own framework that will transform the JPA into JDBC transactions. I tried telling them how annotations (@table, @columns etc.)or hbm (attributes tablename, classname) file plays its role into this and I will create my own XML to parse the entities and transactions. -To write a code that will draw a tank at runtime based on variable capacity and amount of water contained, capacity and amount are continously changing at the background. Later I realised the main requirement is to draw a stock market chart, which is updated at runtime depending upon the stock prices. However the answer was quite simple to use a javascript onhange or ValueChangeListener object. I answered all the questions except of last one as it was not clear enough. All the questions were very badly quoted and uncomprehensive.
