How many rounds does TCS have for a Network Engineer interview, and what order do they follow?

Candidates reported 4 interviews for the TCS Network Engineer process. The loop starts with a Technical Screening, then a Behavioral Assessment, and finishes with Practical Assessments focused on scenario-based problem solving. The structure moves from baseline networking knowledge to troubleshooting under realistic constraints.

How difficult is the TCS Network Engineer interview compared to other roles?

For the TCS Network Engineer role, candidates most commonly reported the difficulty as average. With the process beginning at fundamentals and ending with practical scenarios, preparation should prioritize being able to explain concepts clearly and apply them to troubleshooting steps.

What networking topics does TCS test for Network Engineer interviews?

Common tested topics include OSPF, EIGRP, VLANs, trunking, IPv4 addressing, DHCP, ACLs, and Spanning Tree Protocol (STP). You should also be ready for routing comparisons like static versus dynamic routing and loop prevention in Layer 2 using STP. Public sample questions include “Switch Port Security” and “Static vs Dynamic Routing at Scale.”

What practical troubleshooting approach does TCS expect from Network Engineer candidates?

In practical assessments, interviewers evaluate scenario-based problem solving to test real-world troubleshooting skills. The preparation guidance recommends a structured method: clarify requirements, identify potential failure points, and propose a logical step-by-step solution. Communication matters, so be ready to explain your reasoning as you work through the scenario.

What is the offer rate for TCS Network Engineer interviews, and what does that imply?

Candidates reported a 50% offer rate for TCS Network Engineer interviews. With that level of competition, you should focus on covering the core routing and switching areas listed and practicing how you would explain your troubleshooting process in a structured way.

What pay should Network Engineer candidates expect at TCS, and is it level and location dependent?

The provided materials do not include compensation or pay figures for TCS Network Engineer roles. Because pay varies by level and location, you would need those specifics from the job posting or your recruiter to set expectations for your situation.

My interview centered heavily on networking and routing concepts, and it came across as quite difficult. I was asked about routing protocols like RIPv1/v2, OSPF, and EIGRP, including static and dynamic routing ideas.

From there, the questions moved into switching and network operations: VLANs, trunking, VTP, spanning tree variants like STP and RSTP, and also ether-channel. I also covered network services such as HSRP, NAT, DHCP, and IPv4 addressing.

Difficult Positive Hyderābād

My interview leaned strongly toward networking and switching concepts, and it felt difficult because the topics were very specific and detailed. I was asked about routing protocols like RIPv1/v2, OSPF, EIGRP, and static versus dynamic routing. Switching topics also came up in depth, including VLANs, trunking, VTP, STP/RSTP, and Ether-Channel.

They further tested network services such as HSRP, NAT, DHCP, and IPv4 addressing. On top of that, security questions were a major part of the discussion, including switch port security, DHCP snooping, access control lists, and even physical security concepts.
