How many rounds does NTT DATA have for software engineers?

Usually three: an online aptitude + coding test, a technical interview (one or two rounds), and an HR interview. Some campus drives add a Group Discussion.

Is there negative marking in the online test?

Publicly described drives report no negative marking, but sectional minimum cut-offs apply, so you must clear every section — not just score high overall.

Which programming language should I use?

Any one you are fluent in — C, C++, Java, or Python. Depth in one beats shallow familiarity with several.

How hard is the coding?

Mostly easy-to-medium: arrays/strings, searching/sorting, linked lists, recursion, and the occasional simple DP. Correctness, complexity, and edge cases matter more than exotic tricks.

What CS fundamentals should I revise?

DBMS and SQL, the OOP four pillars, operating-systems basics (process vs thread, deadlock, paging), and a little computer networking.

NTT DATA Software Engineer Interview

A proctored aptitude + coding online test, a technical interview on DSA and CS fundamentals (DBMS, OOP, OS), and an HR round — the classic NTT DATA graduate-hiring funnel.

The NTT DATA interview, in brief

NTT DATA is one of the world’s largest IT-services companies and a large graduate employer, hiring associate software engineers and technical graduate trainees at scale, largely through campus and off-campus drives. Its process is aptitude-heavy at the top of the funnel: a single proctored online test blends quantitative ability, logical reasoning, English, and computer-programming fundamentals, and only a moderate-difficulty adaptive filter is needed to reach the interviews. The technical interview is fundamentals-first — DSA in one language, DBMS/SQL, OOP, operating systems, and a walk through your resume projects — rather than a heavyweight distributed-systems bar. An HR round closes on communication, teamwork, relocation, and long-term fit.

Standard flow: (1) an online aptitude + computer-programming test (proctored, no negative marking, sectional cut-offs, adaptive) then (2) a technical interview covering DSA, DBMS/SQL, OOP, one programming language, and project deep-dive — one or two rounds depending on campus — then (3) an HR interview. Some campus drives add a Group Discussion between the test and the technical round.

Interview rounds

Online aptitude + coding test Proctored online, ~99 questions in ~120 min

Four sections — Quantitative Ability, Logical Reasoning, English, and Computer Programming (DBMS, Computer Networks, OOP, OS, C/C++). Sectional minimums apply; no negative marking; accuracy matters more than attempts because the pattern is adaptive.
Group Discussion (some campuses) Panel GD, ~10–15 min

Only in some campus drives. Assesses clarity of ideas, listening, and teamwork on a general or current-affairs topic.
Technical interview 1–2 rounds, ~30–45 min each

DSA problem in your chosen language (arrays/strings, searching/sorting, linked lists, recursion), DBMS and SQL, OOP pillars, operating-systems basics, and a deep-dive on your resume projects. A basic program may be asked live.
HR interview ~15–30 min

Behavioural and fit — motivation to join NTT DATA, teamwork, strengths/weaknesses, relocation and shift flexibility, and long-term goals.

Coding & DSA topics

Arrays and strings (reverse, palindrome, two-sum, second-largest)Searching and sortingLinked lists, stacks and queuesHash maps and frequency countingRecursion and basic backtrackingBasic trees / BST traversalSimple greedy and dynamic programmingTime and space complexity analysis

System design

Design is light for associate/fresher roles: object-oriented / low-level modelling (a library system, an ATM, a parking lot) and a small schema or data model for a simple application, judged on a clean class model and the OOP pillars rather than distributed-systems scale.

Behavioural round

Expect motivation (“why NTT DATA?”), a project you owned, a hard technical decision or a conflict you resolved, teamwork, and practical fit — relocation, shift flexibility, and willingness to keep learning. STAR-structured, specific answers land best.

Representative question categories

Patterns in NTT DATA’s style — not verbatim proprietary questions.

DSA / codingGiven an array, find the second-largest element in a single pass — and state the complexity.
DBMS / SQLWhat is the difference between a primary key and a foreign key, and when would you add an index?
OOPExplain the four pillars of OOP with an example from a language you know.
Operating systemsWhat is the difference between a process and a thread, and what causes a deadlock?
Aptitude / logical reasoningA work-and-time or ratio problem, or a coding-decoding logical-reasoning question.
HR / behaviouralWhy do you want to join NTT DATA, and are you open to relocation?

How to prepare

Do

Optimise for accuracy, not attempts — the online test is adaptive and has sectional cut-offs.
Clear each section: don’t neglect English or logical reasoning to over-invest in coding.
Be fluent in exactly one language (C, C++, Java, or Python) rather than shaky in three.
Revise DBMS/SQL and the OOP four pillars — they come up in almost every technical interview.
Know your resume projects cold: your role, the stack, and one hard decision you made.
State time/space complexity for every solution, and dry-run the edge cases aloud.

Avoid

Blindly attempting every question and tripping a sectional cut-off through wrong answers.
Memorising OOP or DBMS definitions without being able to give an example or apply them.
Jumping straight to code without clarifying the problem or naming edge cases.
Claiming projects on the resume you cannot explain end to end.
Ignoring aptitude and English, assuming coding alone carries the test.
Being vague about relocation or shift flexibility in the HR round.

Who can apply

Typically B.E./B.Tech in CSE, IT, ECE, or allied branches (some drives include MCA/M.Sc.) with around 60% or above throughout and no active backlogs at joining. Exact criteria vary by drive — confirm on the official posting.
