The overall difficulty of the NTT Data online test is rated easy to moderate for the aptitude sections (Quantitative, Logical, Verbal) and moderate to high for the Computer Programming section. The programming section is the toughest, with questions covering DBMS, computer networks, OOP, C/C++, OS, and Unix. Time management is critical - candidates reported that the aptitude section was approachable but required speed, while the programming section required strong conceptual clarity. Candidates who practiced AMCAT-style questions and focused on the programming section reported clearing the written test successfully.

Some NTT Data on-campus drives include a separate coding round with 2 DSA questions to be solved in 60 minutes. This round is not present in all drives and varies by campus. When present, it evaluates problem-solving skills, coding proficiency, and algorithmic thinking.

• Artificial Intelligence: Boon or Bane
• Digital India: Achievements and Challenges
• Social Media: Benefits and Risks
• Is Remote Work the Future?
• Climate Change and Corporate Responsibility
• Should Engineering Education Be Reformed?
• Cashless Economy: Pros and Cons

The GD round is rated moderate. Candidates who speak confidently, make structured points with examples, listen actively, and summarize well are typically shortlisted. The key is to contribute meaningfully without dominating the discussion. Candidates should avoid getting into arguments and maintain a calm, respectful tone throughout.

• Self-Introduction and Resume Walk-through: Education, skills, and career interests
• Project Discussion (Major Focus): Detailed walk-through of final year and mini projects - objectives, architecture, technology stack, your specific contribution, technical challenges, and outcomes. Interviewers ask detailed follow-up questions about the technical decisions made.
• OOP Concepts: Inheritance, polymorphism, encapsulation, abstraction - explain with examples and code. Differences between abstract class and interface, overloading and overriding.
• Data Structures and Algorithms: Arrays, linked lists, stacks, queues, trees, searching, sorting - explain operations, time complexities, and write code on whiteboard.
• DBMS and SQL: Normalization (1NF, 2NF, 3NF), joins, ACID properties, write SQL queries (e.g., find second highest salary, use GROUP BY and HAVING).
• Operating Systems: Process vs thread, deadlock conditions, virtual memory, paging, scheduling algorithms.
• Computer Networks: OSI model layers, TCP vs UDP, DNS, HTTP/HTTPS, subnetting basics.
• Programming Language Fundamentals: Data types, pointers, memory management, output prediction in the candidate's preferred language (C/C++/Java/Python).
• Unix/Linux Basics: Basic commands (ls, cd, grep, chmod), file permissions, daemon processes.

For Non-CS/IT Candidates: The technical interview covers 2-3 subjects from the candidate's engineering domain (e.g., for ECE - digital electronics, signals and systems, microprocessors) along with basic programming questions.

Candidates reported that interviewers are generally professional and allow time to think. Communication skills are important - the ability to explain technical concepts clearly matters as much as knowing the correct answer. Being honest about gaps in knowledge is appreciated.

• Self-Introduction: Concise overview of background, education, and interests
• Why NTT Data?: Motivation to join NTT Data, knowledge of company values and global presence
• Career Goals: Where you see yourself in 3-5 years, long-term aspirations in IT
• Strengths and Weaknesses: Self-awareness with specific examples and improvement strategies
• Behavioral Questions: Teamwork experience, handling pressure, handling failure, conflict resolution
• Work-Life Balance: How you manage personal and professional commitments
• Adaptability: Willingness to learn new technologies, relocate to any NTT Data location in India
• Achievements: Academic, extra-curricular, or technical accomplishments
• Company Knowledge: Understanding of NTT Data's services (digital consulting, AI, cloud, managed services), global operations (50+ countries, 140,000+ employees), and Japanese heritage
• General Discussion: Hobbies, current affairs, interests

Candidates reported that the HR round is generally conversational and friendly. The interviewer primarily evaluates communication skills, grammatical accuracy, vocabulary, confidence, and how candidates present themselves. Results for on-campus drives are typically declared on the same day.
