I went through consultancy firm. Before this I went before two months at dupont at that time I have not cleared versent test. But this time I have cleared the all test. At versent test only I have asked is any technical problem due to earlier interview process. That hr said no issue. At the end of the day. She said we are not going to take ur interview further. If she said at morning I would save my half day. Presently I am working also. She said afternoon after 20 mnts you have technical round of interview. This type of behaviour is not expected with mnc. As per my experience dupont interview process is worst. Of you ask how much dirty I can't explain in words. I can tell only one word in telugu dupont interview process is "chendalam"
