Knovos Java Trainee interview questions

I applied to Knovos (Ahmedabad) through campus placements. I went through only half interview process. The first round was aptitude test which was easy. The second round was a technical interview. The interviewer was very patient.

They take an written aptitude test. After the test they call each person for PI regardless of their performance in the test. They ask questions based on the answers given in test. After the PI some shortlisted candidates appear for a GD in front of the Team Lead. On the basis of GD performance Team Lead Selects the final candidates.
