GreyCampus interview questions

1st round was aptitude of 30 easy MCQ following programming questions like postfix and infix, queue and basic c language.Third round was Hr round which was very easy.But i didnt get selected.

I have been there via campus interview, 450 members have written the exam where only 30 of them were shortlisted, I was one among them. All the 30 were called to the office for further round interviews, only 8 were shortlisted of 30 in group discussion and 3 of them were placed after a HR round. It does not provide cab facility or food facility.
