Intellect Design Arena Trainee Software Engineering interview questions

The first round was Aptitude, English verbal, and pseudo code. It was quite easy and if you have the basic idea about aptitude questions and know how to solve simple pseudo code you can clear the round very easily. Then there was a technical round, it was a bit tough there was only one interviewer, He asked me simple java related questions like access modifier, exceptions, object class, and questions related to OOPS like inheritance, abstraction, encapsulation, and simple SQL queries. Try focusing more on OOPS and SQL. The interviewer was very helpful he gave me hints when he asked me to write SQL queries. The last round was GD where I experienced the worst management from them. I think their HR's don't interact with each other because I got the same mail from them 3 times and when asked about it no reply from them. And I think they don't even know how to reply to emails because for one of my mail they reply very informally with lots of grammatical errors. They told me they will get back to me soon but even after a month, I haven't got any reply from them.
