From your question it seems that you are applying/trying for your first job. In that case, what I would recommend is that you have your fundamentals pretty well under your belt. Have a thourogh knowledge of the projects you did in college and be thourogh with the computer science fundamentals. Ability to write short programs and demonstrate logical thinking through use of flowcharts would be an advantage. In the interview , do not try to show that you are master of everything, but instead talk about your core strengths and invite any questions in that area. Of course, choose a company that has work in the area which match your core strengths.all the best.rgdskabir...
