I went for Datacomp company. Firstly, they came really late they told us to come at 9 sharp and they arrived at 11.30! They took aptitude test which had 20 questions and was pretty easy. After that, they selected students and then took technical MCQ test and then GD. They didn't announced the results after the first apti. They said they'll judge the technical and GD points and then they'll mail us. The management wasn't good at all. Be prepare to be there till 5-6!
