Tata Consultancy Services System Engineer interview questions

i was hired through campus recruitment....interview process has routine written, gd, technical and hr interview. interview process was easy for me. basic questions were asked from the academics...it would be helpful if we brush up once before recruitment process

Interview is on campus, very process oriented and professional. First attended a written test, which has analytical questions. and next is interview round which had few basic questions of oops concepts and college projects
