I applied through college or university. The process took 1 week. I interviewed at Tata Communications (Chennai) in Nov 2017
Interview
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.
It was easy.
1> Introduction
2> Favourite Subjects: Control systems, Digital Circuits and Signals and Systems.
Questions were related to Digital Circuits: Flipflop, Combinational Circuits
Signal and Systems: Fourier Transform
The interview process for a network engineer typically begins with a phone screening, focusing on the candidate's technical background, certifications, and experience with networking protocols and equipment. A technical interview follows, where candidates solve real-world networking scenarios or problems and may be asked to configure devices or troubleshoot network issues. Questions on routing, switching, security, subnetting, and protocols like BGP or OSPF are common. Some companies include hands-on lab assessments or simulations. The final rounds often involve a behavioral interview to assess teamwork, communication, and problem-solving skills. The process aims to gauge both technical proficiency and cultural fit.
Interview questions [1]
Question 1
Can you explain the OSI and TCP/IP models? What are the key differences?
How does subnetting work, and why is it important? Can you calculate a specific subnet mask?
Describe the differences between TCP and UDP. When would you use each protocol?
Explain BGP and OSPF. How do they differ, and when would you use one over the other?
What are VLANs, and how do they work? Why are they used in network design?
How do you troubleshoot network latency issues? What tools and steps would you use?
What is NAT, and how does it help with IP address management?
Can you describe the process of setting up a VPN?
How do firewalls work, and what’s the difference between stateful and stateless firewalls?
Explain load balancing and the methods commonly used for it.
It was a good , but my profile was more like Developer so they rejected me, it was on campus opportunity, first there is online test then technical interviews. overall nice experience,
