The question is kinda easy if you already prepare before the interview because they asked about Java and SQL. You need to study a lot on the terms such as JVM, JDK, and so on. They asked you what actually you know about Java. You need to know how to do sql query also. It's really good experience if you already do some project in Java maybe during your final year project so that you can talk about that too. Main point is they want to see either you have logical thinking about Java and SQL . This is what I've been asked. It might differ to other candidates.
