A bunch of people think that once your CV is accepted, you will right away find yourself in the work and enjoy its wonderful benefits and positives. Contrary to appearances, it is actually difficult to answer all Java interview questions properly, particularly if we don't know very well what exact duties we must fulfil.
Needless to say every boss may demand from us experience about other field of expertise. That's the reason most of us should really know what the expectations in our future manager are and whether we can handle fulfilling them.
The capability to work in group, the requirement to always be current with recent changes and inventions, and many other demands - this is how the life span of java scripter looks like. As you know, the job as JAVA writer takes a lot of knowledge about programming and many other skills. So, do not wait around any longer.
