Tata Steel interview questions

First we had a written test for both technical and aptitude paper. aptitude questions were easy, prepare with r.s. agarwal book that would be sufficient. for technical paper prepare by using gate book and you will get through written test easily. Out of 80 student 20 were selected. After that we had group discussion round in which 2 groups were formed, and 10 students were selected for PI round. Interview was mostly technical, although 1 or 2 math trick question were also asked. Out of 10 only 4 students were selected

because i am an experienced candidate and applied for manager post, so i was interviewed by executive director 1to 1.
