TCS AU

• Very reliable 482 visa sponsor — one of the highest volumes in AU
• Exposure to enterprise clients (ANZ, NAB, Telstra, government agencies)
• Structured onboarding — TCS Initial Learning Program (ILP) is comprehensive
• Large AU network — easy to find internal references and switch projects
• Stable employment — low layoff risk during economic downturns

• Compensation (2.8/5) — significantly below AU market rates
• Billable hours culture — advancement based on utilisation and seniority, not merit
• Limited technical depth — often implementing, not designing or architecting
• High-utilisation expectations — overtime expected on many projects
• Treated as a resource, not a colleague by many AU clients

"Explain the four pillars of Object-Oriented Programming — encapsulation, inheritance, polymorphism, and abstraction. Give a code example for each."

💡 Core TCS technical question. Be ready to write actual Java or Python code for each concept — don't just define them.

"Write a function to reverse a singly linked list. What is the time and space complexity of your solution?"

💡 Standard TCS coding question. Iterative solution is O(n) time O(1) space — preferred over recursive which uses O(n) stack space.

"What is the difference between a process and a thread? When would you use multi-threading versus multi-processing?"

💡 OS fundamentals — TCS tests this across roles. Key: processes have separate memory spaces, threads share memory within a process.

"Write a SQL query to find the second highest salary from an Employee table. What if there are duplicates?"

💡 Classic SQL interview question. Solutions: subquery with MAX, DENSE_RANK(), or LIMIT OFFSET depending on the database.

"Tell me about yourself — walk me through your background, your key technical skills, and why you're interested in TCS Australia."

💡 Prepare a tight 2-minute pitch: education → key skills → relevant experience → why TCS AU specifically (visa pathway, enterprise clients, stability).

"Where do you see yourself in 5 years, and how does TCS fit into that plan?"

💡 Standard HR question — be honest that you want to grow into a senior engineer or architect role. Mention interest in TCS's AU enterprise clients and global mobility options.
