Tata Communications interview questions

I was selected from college campus interviews. 1. Aptitude test+ Technical test 2. Group discussion 3. Techinal/HR

GD followed by Interview. In the GD, there were separate topics for each individual for which that person had to act as the moderator and others could participate. Following that there was a shortlist for Interviews. Interview was very short which appeared to be more of a timepass than an interview. There is no point preparing for interview for this company.
