Tata Communications interview questions

first there was a PPT in which they explained abt the company and its business. initially i did not know much abt company but in their PPT i was really very much impressed. only ECE students were allowed for placement by tata communications. after that there was written test that comprised of 2 sections..1 technical 2. aptitude in technical there were very basic questions from basic electronics, computer networking, operating systems in aptitude qustions were quite easy, from profit loss,percentage,time-speed, interest,simple ,calculations based..but speed matter here a lot.. total (tech + apti) there were 50 questions from 60 mins out of a total of 290 students 45 were shortlisted for next round. next round was technical interview. in technical interview they were asking qustions like: 1. tell me abt urself 2.explain ur project they ll ask you ur domain (they prefer it computer networks and optical communication related) 3. basic networking questions. 4.c programming and data structure questions from tree and linked list (i was also shocked, why they are asking data structure, but don;t worry they just expect the algorithm from you) my technical interview lasted for 20 mins after that i was called for HR interview.. HR lady asked me only single question.."tell me abt yourself"..and she was impressed.. next day i got the result and i was selected..
