After the HR thing, the technical questions were asked: Java Beans, life cycle of a servlet, what is foreign key, types of databases, difference between relational and hierarchical databases, etc. Now, there were times I answered questions wrong or blanked out. So, just don't lose it when it happens. Be calm, things will go well.
There were also interviewers, I heard who were asking questions on linked lists and other data structures. But people who explained the logic were through, I think. People from non-Computer Science branch gave the interview too and if they could explain things, say the logic, for example the steps in making a project (requirement analysis, design, coding, release and maintenance) they were through.
