HCL GET Interview Questions 2026: Graduate Engineer Trainee Rounds with Answers

This page is for 2026 batch engineering students preparing for HCLTech's Graduate Engineer Trainee (GET) hiring, on campus or through the off-campus drives HCLTech runs in cities like Bengaluru and Chennai, and for Class 12 students looking at TechBee who want to know how the interviews compare. It explains eligibility, the rounds, what each round asks, and gives 30 questions with model answers.

HCLTech's GET interview is one of the more approachable among the large Indian IT recruiters. Candidates consistently describe it as resume-driven: the panel picks your stack and your project and asks from there. That makes it easy to prepare for and easy to fail if your resume promises more than you can defend.

How the HCL GET process works in 2026

As of September 2026, HCLTech's campus hiring page lists Graduate Engineer Trainee, Graduate Trainee, Post Graduate Trainee and specialised hiring as its entry routes, and the TechBee site describes the early-career programme. Neither publishes the assessment pattern or CTC. The following comes from the official pages, the July 2026 GET posting as reported by placement sites, and candidate experiences.

Eligibility (July 2026 off-campus GET drive). UG 2026 batch only; BE or B.Tech in CSE, IT, EEE, ECE or EIE; 70% or equivalent CGPA in Class 10, Class 12, UG and PG if applicable; no backlogs; willingness to relocate anywhere in India; interviews held in Bengaluru and Chennai. Campus drives set their own thresholds, and candidate experiences mention 60 to 70% throughout. That drive is now closed; new ones appear on careers.hcltech.com and through placement cells.

The rounds.

1. Online assessment. A GeeksforGeeks on-campus experience describes 75 questions in 90 minutes: logical, verbal and quantitative reasoning, technical MCQs on DBMS, OOP, computer networks, software testing and operating systems, and coding exercises. Other drives report a Java MCQ plus two-problem coding section, with problems on inheritance and control flow.
2. HR or document screening. Verification of Aadhaar, Class 10, Class 12 and UG mark sheets against the eligibility criteria before interviews.
3. Technical interview. Resume-driven: your project, your language, OOP, DBMS, and if you claim a web stack, JavaScript and framework fundamentals. Some drives add a JAM (just a minute) speaking round to check communication.
4. HR interview. Conflict handling, relocation across India, the service agreement, hobbies, achievements, goals.

CTC. The July 2026 posting did not disclose salary. Placement sites report candidate offers of about ₹3.5 to 5 LPA for GET roles depending on specialisation. HCLTech does not publish a band.

TechBee, for comparison. For Class 12 pass-outs, reported eligibility is 60% in Class 10 and Class 12 with an age band of about 17 to 20; selection is an online aptitude test of about 60 minutes (quantitative, logical, English, basic IT), a group discussion or technical round, and an HR interview. Beincareer reports a training stipend of roughly ₹3 to 3.5 LPA in the first year, a degree through partner universities alongside work, and absorption as an IT Analyst afterwards. These are third-party figures; hcltechbee.com is the reference.

After the offer. HR asks about relocation and a service agreement in nearly every GET interview; the terms are in the offer letter. Joining is staggered by batch.

What HCL GET interviewers are testing

• Is the resume true? Every stack you list gets a question.
• Fundamentals. OOP, DBMS with SQL, OS basics, networking basics, SDLC and testing basics, one language in depth.
• Your project. Why you chose it, your exact contribution, database design, challenges, testing, deployment, what you learned.
• Communication. The JAM round where it exists, and the clarity of every answer where it does not.
• Flexibility. Pan-India relocation is in the job posting itself; the HR panel confirms you meant it.

30 HCL GET interview questions with model answers

Programming and OOP

1. Which programming language are you strongest in?

"Java for backend work and JavaScript for the front end, because my project used both. I also know C from first year and Python for scripts. If HCLTech's training uses a different stack I am comfortable learning it." Pick one to be examined on and say so.

2. Explain the four pillars of OOP with examples from your project.

"Encapsulation: my Order class keeps items private and exposes addItem() with validation. Abstraction: the controller calls an OrderService interface. Inheritance: OnlineOrder and CounterOrder extend Order. Polymorphism: each overrides deliveryCharge() and the billing code does not care which."

3. What is inheritance in Java, and what is the super keyword for?

"Inheritance lets a class reuse fields and methods of a parent through extends. super calls the parent's constructor or a parent method that the child has overridden; for example super(name) in a child constructor, or super.toString() inside an overridden toString()."

4. Write a program using a switch statement to print the day of the week for a number.

"Read an integer, switch on it with cases 1 to 7 returning Monday to Sunday, and a default for invalid input. In modern Java I would use the arrow form to avoid fall-through. I would also validate the input before the switch." Candidates report exactly this kind of program in HCL coding rounds.

5. What is the difference between an abstract class and an interface?

"An abstract class can hold state and shared code and supports single inheritance; an interface is a contract that many unrelated classes can implement. Shared code and state: abstract class. Common capability across unrelated types: interface."

6. What is exception handling? Why use finally?

"try holds risky code, catch handles a specific exception, finally runs regardless of outcome, usually to close a file or a database connection. In Java I prefer try-with-resources for anything closeable. I catch specific exceptions and log context rather than catching Exception blindly."

7. Explain JavaScript hoisting and the difference between var, let and const.

"Hoisting moves declarations to the top of their scope at parse time; var declarations are hoisted and initialised as undefined, let and const are hoisted but stay in a temporal dead zone until declared. var is function-scoped; let and const are block-scoped; const cannot be reassigned. I default to const."

8. What is a promise in JavaScript?

"An object representing a value that will arrive later, with then for success, catch for failure and finally for cleanup. async and await are syntax over promises. In my project I used them for API calls so the UI did not block while waiting for the server."

9. What is the virtual DOM in React?

"An in-memory copy of the real DOM. When state changes React builds a new virtual tree, diffs it against the previous one, and applies only the minimal changes to the real DOM, which is what makes updates fast. I would mention keys in lists so the diff stays correct."

Data structures and algorithms

10. Array versus linked list, and when would you choose each?

"Array: contiguous memory, O(1) index access, O(n) insertion in the middle. Linked list: nodes with pointers, O(1) insertion at a known node, O(n) access. Arrays for lookup and index-heavy work; linked lists for frequent inserts and deletes."

11. Write a program to reverse a string without built-in functions.

"Two pointers on a character array, swap and move inward; O(n) time, O(1) extra space. I would handle null and empty strings and mention that String is immutable in Java so I convert to a char array first." Then write it and dry-run on 'HCL'.

12. Explain binary search and its complexity.

"On a sorted array, compare the middle element with the target and discard half each step; O(log n). It needs random access, so it degrades on linked lists. I use the overflow-safe midpoint low plus (high minus low) divided by two."

13. What is a stack? Give two real uses.

"Last in, first out. Uses: function call stack and undo in an editor; also checking balanced brackets in a compiler. I implemented one for expression evaluation in a lab."

DBMS and SQL

14. What is normalisation? Explain up to 3NF.

"Removing redundancy and update anomalies. 1NF: atomic values. 2NF: every non-key column depends on the whole key. 3NF: no transitive dependencies. My project's Order and Customer tables were in 3NF; the reporting view was denormalised on purpose."

15. Difference between primary key, unique key and foreign key?

"Primary key: unique, not null, one per table. Unique key: unique, may allow a null, several per table. Foreign key: references another table's primary key to enforce a relationship, so an order cannot point to a missing customer."

16. Write a query to find the second-highest salary.

"SELECT MAX(salary) FROM employee WHERE salary < (SELECT MAX(salary) FROM employee), or DENSE_RANK() OVER (ORDER BY salary DESC) filtered to rank 2 to handle ties."

17. Explain INNER JOIN versus LEFT JOIN with an example.

"INNER JOIN returns matching rows only: customers who have orders. LEFT JOIN returns all rows from the left table with nulls where there is no match: all customers including those with zero orders, which is what a sales dashboard usually wants."

OS, networks, testing and SDLC

18. Process versus thread?

"A process has its own memory space; threads share their process's memory and are cheaper to create and switch. Shared memory means shared data needs locks to avoid race conditions."

19. What is the difference between TCP and UDP?

"TCP is reliable, ordered and connection-oriented; UDP is connectionless and faster with no delivery guarantee. Web and email use TCP; video calls and DNS use UDP."

20. What is SDLC? Name the phases and one model.

"Software development life cycle: requirements, design, development, testing, deployment, maintenance. Waterfall runs them in sequence; Agile runs them in short iterations with working software each sprint. My project used two-week sprints with a demo at the end of each."

21. Difference between unit testing and integration testing?

"Unit tests check one function or class in isolation, usually with mocks; integration tests check that components work together, like the API talking to the real database. I wrote JUnit unit tests for the pricing logic and a few integration tests against a test database."

22. What is cloud computing, and what are IaaS, PaaS and SaaS?

"Computing resources rented over the internet on demand. IaaS is raw infrastructure like a virtual machine, PaaS a managed platform like a hosted database, SaaS a finished application like Microsoft 365. HCLTech has a large cloud practice, so I have started with AWS basics."

Project

23. Why did you choose your project, and what was your exact contribution?

"I chose a canteen ordering system because our college canteen had queues at lunch and the problem was real. I owned the Java backend, the MySQL schema and deployment; my teammate owned the React front end; we designed the API together. The GitHub history shows the split." HCL panels ask for the split precisely.

24. Describe your database design and one challenge.

"Customer, MenuItem, Order and OrderItem tables in 3NF, with OrderItem storing the price at order time so menu price changes do not alter old bills. The challenge was double-submitted orders; a unique constraint plus disabling the button after the first click fixed it."

25. How did you test and deploy it?

"JUnit for pricing logic, manual test cases for the ordering flow, and a two-week pilot with the canteen. Deployment was on a free cloud tier with a script that builds and restarts the service. If I did it again I would add automated API tests." Script for the full project answer: explain your final-year project.

HR round

26. Tell me about yourself.

Under ninety seconds: name, place, degree and college with CGPA, one project, one skill, why HCLTech. Guide: tell me about yourself.

27. Why HCLTech?

"HCLTech's engineering and product services work is closer to core engineering than pure IT services, which suits my background. The GET programme has structured training, and HCLTech's cloud and infrastructure practices are where I want to grow. I also like that the company invests early through TechBee; it says something about how it treats freshers." Add one honest personal reason.

28. How would you resolve a conflict in your team?

STAR. "In our project two of us disagreed on the database. I proposed a fifteen-minute call where each listed the top two reasons, we picked the one both had used before, and we wrote the decision down. We finished on time. My rule: decide fast, document it, move on."

29. Are you willing to relocate anywhere in India and sign the service agreement? Any other offers?

"Yes to relocation; the posting said pan-India and I applied knowing that. I will read the exact agreement terms in the offer letter and I am comfortable with a standard fresher agreement. I have one other offer from Cognizant GenC; I would choose HCLTech for the engineering focus." Facts that match your documents; see why should we hire you for the closing pitch.

30. What are your hobbies and biggest achievement, and do you have questions for us?

One hobby with a detail, one achievement with a number, two questions. "I play district-level table tennis, which taught me to lose calmly. My achievement is that the canteen actually used our system for two weeks. My questions: what does GET training look like before project allocation, and how are freshers assigned to practices?"

Mistakes that get freshers rejected at HCL GET

• A resume that lists a stack you cannot answer on. HCL panels ask from the resume; remove what you cannot defend.
• A group project with no clear personal contribution.
• Weak SQL or OOP basics despite a strong coding score.
• Refusing pan-India relocation after applying to a posting that requires it.
• Failing the JAM round where it exists, by running out of things to say in a minute.
• Document mismatches on backlogs, gaps or percentages at the screening stage.

How to practise the HCL GET rounds

Because the GET interview is resume-driven, the highest-value practice is answering follow-ups on your own resume, out loud, under time pressure.

In MockMate Practice, attach your resume and paste the HCLTech GET job description, choose a technical round and run a ten-minute adaptive session in the browser; the interviewer persona picks stacks from your resume the way an HCL panel does and the technical round includes a code editor for the switch-statement and reverse-a-string programs. Run a second ten-minute HR round for relocation, the agreement, conflict and goals; if your drive has a JAM round, use the HR session to rehearse speaking for a full minute on one topic. Each session ends with a report showing every answer, response timing, recurring weaknesses and a recommended next practice. Eligible accounts get three free Practice starts of up to ten minutes each. Use MockMate Live assistance only in interviews or meetings where the organisation or interviewer permits it; when permission is unclear, which is the case for HCLTech assessments and interviews, stay with Practice.
