KPIT Technologies Associate Engineer interview questions

I went through college reference, It was an off campus round. the process wasn't well managed first they invited 85(from different colleges)of us @9am.Then after few minutes of waiting they call 25 students to give an aptitude test(quant,logical,English).I don't understand the reason for the test because they started technical interview of remaining student in parallel to test.After the interview, they asked those student who gave the exam to sit for GD round.It was all confusing and messy.
