About Tata Communications
Tata Communications is a global digital ecosystem enabler headquartered in Mumbai and part of the Tata group. It owns one of the largest subsea fibre networks in the world and provides connectivity, cloud and edge, cybersecurity, collaboration, IoT and media services to enterprises, telecom carriers and over-the-top platforms in more than 190 countries. Its largest workforce is in India, across Mumbai, Pune, Chennai, Bengaluru, Hyderabad and Delhi NCR.
The company hires network and NOC engineers, cloud and DevOps engineers, cybersecurity analysts, software developers, solution architects, product managers, enterprise sales and account managers, and finance and operations professionals. Freshers join through campus drives at engineering and management colleges and through periodic off-campus tests; the company also runs early-career programmes that rotate graduates across functions.
Tata Communications looks for strong networking and systems fundamentals, customer orientation and comfort in a 24x7 service environment. As a Tata company it also weighs integrity and teamwork heavily, and interviewers often ask about the group's values.
Tata Communications hiring process
The hiring process is a mix of online assessment and two to three interviews, largely virtual in 2025-26. It runs like this for most engineering and business roles.
1. Application
Apply on the Tata Communications careers portal, through a campus placement drive or via a job portal such as Jobaaj. Tag your profile clearly to a domain such as network, cloud, security, software or sales, because shortlists are domain-specific.
2. Online assessment
Fresher and early-career candidates take a proctored online test with quantitative aptitude, logical reasoning, verbal ability and a technical section on networking, programming or telecom fundamentals depending on the role. Sales and management trainee roles may get a situational judgement test instead.
3. Technical interview
A 45 to 60 minute interview with a domain engineer. Network roles cover the OSI model, routing and switching, MPLS and troubleshooting; cloud roles cover Linux, virtualisation, containers and automation; security roles cover threats, SIEM tools and incident handling; software roles cover data structures and a language of your choice.
4. Managerial interview
The hiring manager assesses how you would fit into a live operations or delivery team: shift readiness, customer communication, ownership during incidents and, for experienced hires, how you have handled escalations and projects.
5. HR discussion
A short round on compensation, location, notice period and Tata values. Freshers may be asked about their understanding of the company and willingness to work rotational shifts in NOC or support roles.
6. Offer and background verification
Offers are followed by document verification and a background check. Fresher batches usually join a structured induction and technical training programme before being assigned to a team.
Tata Communications interview rounds
Most candidates go through three to four rounds. Network and operations roles put more weight on troubleshooting scenarios; software roles on coding.
Round 1: Online assessment
A 60 to 90 minute proctored test. Sectional cut-offs are common, so balance your time across aptitude and technical sections.
- Quantitative aptitude, reasoning and English
- Networking basics: IP addressing, subnetting, TCP versus UDP
- Programming MCQs or a short coding problem for software roles
Round 2: Technical interview
A 45 to 60 minute live interview with a senior engineer, often including a whiteboard or shared-screen troubleshooting exercise.
- Explain the OSI and TCP IP models with real examples
- Walk through diagnosing a customer link that is up but dropping packets
- BGP versus OSPF, MPLS basics, VLANs and NAT
- Linux commands, scripting and container basics for cloud roles
Round 3: Managerial interview
A 30 to 45 minute conversation with the hiring manager about customer handling, incident ownership and working in a global 24x7 environment.
- Describe an outage or critical issue you handled end to end
- How do you communicate bad news to a customer?
- Prioritising multiple tickets with different SLAs
Round 4: HR round
A 15 to 30 minute discussion on fit and logistics.
- Why Tata Communications rather than a product company?
- Comfort with rotational shifts and on-call duty
- Salary expectations and preferred location

Tata Communications interview FAQs
Q1How many rounds are there in the Tata Communications interview process?
Usually three to four: an online assessment for freshers, a technical interview, a managerial interview and an HR discussion. Experienced candidates sometimes skip the online test and may face two technical rounds instead. From application to offer the process typically takes two to five weeks, with campus drives finishing much faster.
Q2How difficult is the Tata Communications technical interview?
Moderate, with a practical bent. Rather than very hard puzzles, interviewers pose troubleshooting scenarios and expect a structured, layer-by-layer approach plus solid fundamentals in networking, Linux or programming. Candidates with a CCNA-level understanding of routing and switching, or equivalent cloud and security basics, generally find it fair.
Q3Explain the difference between TCP and UDP and when each is used.
State that TCP is connection-oriented with sequencing, acknowledgements and retransmission, so it guarantees delivery and order at the cost of latency; UDP is connectionless and lightweight with no delivery guarantee. Give uses: web pages, email and file transfer on TCP; voice, video streaming, DNS and gaming on UDP. Mention that many Tata Communications services such as voice and video rely on UDP-based protocols.
Q4A customer's link shows up but they cannot reach the internet. How would you troubleshoot?
Describe a layered method: confirm physical and link status, check IP configuration and gateway reachability with ping, verify DNS resolution, trace the route to find where packets drop, review routing and NAT or firewall rules, and check for recent changes. Emphasise keeping the customer informed and documenting each step in the ticket for handover.
Q5Why do you want to work at Tata Communications?
Reference something specific, such as its subsea cable network, its role connecting global enterprises, or its growth in cloud, security and IoT, and connect that to the skills you want to build. Add the Tata group's reputation for ethics and stability, and finish with a personal example of interest in networking or telecom.
Q6What is the fresher salary at Tata Communications?
Entry-level engineering roles typically start in the mid-single-digit lakhs per year, with management trainees from business schools placed higher. The package includes variable pay, medical insurance and provident fund. Campus eligibility is usually an engineering or relevant degree with a consistent academic record; networking certifications such as CCNA are an advantage but not mandatory.
