Technoforte Software Java Developer interview questions

I interviewed through the company. They gave two set of questions. One is Java technical questions and another is aptitude questions. Technical questions is easy. But in aptitude it contains of Venn Diagrams, AND,OR NOT GATE kind of questions. Yet, I dint know if they are hiring for java developer post or some Core based post. They were simply wasting the time. They dint hire anyone.
