I applied to Tata communications through our college recruitment process.
They had a unique way of shortlisting candidates through an app. We were asked install the app and used to get daily challenges which were questions based on post we applied for.
Then selected students were called for further process. So basically, their were 4 rounds.
1. GD
2. Technical interview 1
3. Technical interview 2
4. HR
GD and HR were normal. Questions asked in technical interview were based on your subject and area of interest. Since I belong to EEE they didn't ask much network related questions from me, just the basic one however, my friends from ECE, ETC dept were asked quite a few questions from network.
Finally, total 14 students went till hr round, out of which 6 were selected including me.
All the best to all the people applying.
