Randstad Graduate Engineer interview questions

I was in my final year B.E. and willing to attend placement drives for jobs as well as experience. I first wrote the test, it was easy and basically aptitude questions were being asked. I cleared the test and later group discussion was there and the topic was "Is technology helping in Swach Bharat" and I cracked the GD. Later was the HR round and I found that it was basically client support and thats all..
