Graduate Engineer Trainee (GET) · TechBee (post-Class-12)
CoCubes / online assessment (Aptitude + Reasoning + Pseudocode/Technical + optional Coding) + Versant (TechBee only)

HCLTech Interview Questions & Placement Prep (2026)

HCLTech runs two distinct hiring tracks: Graduate Engineer Trainee (GET) for engineering graduates and TechBee for candidates straight out of Class 12. GET typically runs a 6-section CoCubes assessment (Verbal, Logical, Quant, Analytical, Critical Reasoning and Pseudocode) in about 110 minutes, sometimes followed by a coding round, then technical + HR interviews. TechBee runs a shorter aptitude + programming test, a Versant spoken-English assessment, and an interview discussion. This guide covers both syllabi, formulas, previous-year questions, ready code and a week-by-week roadmap.

GET: ~95 MCQs across 6 sections in ~110 min, optional coding. TechBee: ~77 MCQs across 5 sections in ~95 min, plus a Versant spoken-English test and interview.

Previous Year Questions & Patterns

Repeat coding questions with the expected approach.

GET aptitude PYQs

  • A train 150 m long crosses a pole in 10 seconds — speed = 15 m/s = 54 km/h
  • Average of six numbers is 24; removing one number makes the average 20 — removed number = 44
  • A and B complete a job in 12 and 18 days — combined time = 7.2 days
  • Series 2, 6, 12, 20, 30, ? — next term = 42
  • If HCL is coded as ICM, how is TECH coded? → UFDI

Pseudocode / output-prediction PYQs

  • int x = 5; cout << x/2 + x%2; → Output: 3
  • Nested loop: for(i<n) for(j<n) cout<<i+j; → Time complexity O(n²)
  • Which structure follows LIFO? → Stack
  • Which normal form removes partial dependency? → Second Normal Form (2NF)
  • Which protocol is connection-oriented? → TCP

TechBee PYQs

  • Remainder when 125 is divided by 7 → 6
  • Series 5, 10, 20, 40, ? → 80
  • Walking north then turning right — facing direction → East
  • int sum=0; for(i=1;i<=5;i++) sum+=i; cout<<sum; → Output: 15
  • First index of an array in C++ → 0

Verbal & grammar PYQs

  • Choose the correct sentence: 'He do his work daily' vs 'He does his work daily' → the second
  • All databases contain records; some systems contain databases — can we conclude some systems contain records? → Yes

HR & interview questions

  • Tell me about yourself; why HCLTech?
  • Explain your academic or personal project and your individual contribution
  • Are you willing to relocate and undergo training?
  • Difference between process and thread; what is a deadlock?
  • Write a query using JOIN and GROUP BY

20+ SQL Query Bank

Write these out by hand — joins and subqueries are asked in both the test and the interview.

Basics & aggregation

Filter and sort

SELECT name, department
FROM employees
WHERE salary > 50000
ORDER BY salary DESC;

Aggregates

SELECT COUNT(*) AS total,
       AVG(salary) AS avg_salary,
       MAX(salary) AS max_salary
FROM employees;

GROUP BY with HAVING

SELECT department, COUNT(*) AS emp_count
FROM employees
GROUP BY department
HAVING COUNT(*) > 5;

Joins

INNER JOIN

SELECT e.name, d.department_name
FROM employees e
INNER JOIN departments d
  ON e.dept_id = d.dept_id;

LEFT JOIN

SELECT e.name, d.department_name
FROM employees e
LEFT JOIN departments d
  ON e.dept_id = d.dept_id;

SELF JOIN — employee and manager

SELECT e1.name AS employee, e2.name AS manager
FROM employees e1
JOIN employees e2
  ON e1.manager_id = e2.emp_id;

Subqueries

Second-highest salary

SELECT MAX(salary) AS second_highest
FROM employees
WHERE salary < (SELECT MAX(salary) FROM employees);

Employees above average

SELECT name, salary
FROM employees
WHERE salary > (SELECT AVG(salary) FROM employees);

DBMS & Core Interview Q&A

Short answers you should be able to say out loud.

What is normalization?

Structuring tables through 1NF, 2NF, 3NF and BCNF to remove redundancy and update anomalies.

Primary key vs foreign key?

A primary key uniquely identifies a row; a foreign key references the primary key of another table.

What is a deadlock?

A cycle where processes wait indefinitely on resources, satisfying mutual exclusion, hold-and-wait, no preemption and circular wait.

Which normal form removes partial dependency?

Second Normal Form (2NF) removes partial dependency on a composite primary key.

What are ACID properties?

Atomicity, Consistency, Isolation and Durability — the guarantees of a reliable database transaction.

Process vs thread?

A process has its own memory space; threads share the memory of their parent process.

TCP vs UDP?

TCP is connection-oriented and reliable; UDP is connectionless and faster with no delivery guarantee.

What is indexing?

A lookup structure that speeds up reads at the cost of extra storage and slower writes.

OOPs Concepts + 10 Code Snippets

Theory plus the exact snippets asked in the technical round.

Encapsulation

Bundle data and methods in a class; keep fields private with public accessors.

Abstraction

Hide internal details, expose only essential features through interfaces or abstract classes.

Inheritance

Base class → derived class using 'extends' (Java) or ': public' (C++).

Polymorphism

Compile-time overloading vs runtime overriding using virtual functions.

Constructor & overloading

Initialise an object; can be overloaded with different parameter lists.

Abstract class vs interface

Abstract class can have partial implementation; interface (Java) is fully abstract and supports multiple inheritance.

Access modifiers

private, protected, public — control visibility of members.

Time complexity basics

Linear search O(n), binary search O(log n), nested loops O(n²), Kadane's algorithm O(n).

1. Encapsulation (Java)

java

class BankAccount {
    private double balance;
    public void deposit(double amount) { balance += amount; }
    public double getBalance() { return balance; }
}

2. Inheritance & method overriding (Java)

java

class Animal {
    void sound() { System.out.println("Some sound"); }
}
class Dog extends Animal {
    void sound() { System.out.println("Bark"); }
}

3. Abstract class (Java)

java

abstract class Shape {
    abstract void draw();
}
class Circle extends Shape {
    void draw() { System.out.println("Circle"); }
}

4. Interface (Java)

java

interface Drawable {
    void draw();
}
class Rectangle implements Drawable {
    public void draw() { System.out.println("Rectangle"); }
}

5. Virtual function (C++)

cpp

class Base {
public:
    virtual void show() { cout << "Base"; }
};
class Derived : public Base {
public:
    void show() override { cout << "Derived"; }
};

6. Reverse a number & palindrome check (C++)

cpp

int reverseNumber(int n) {
    int rev = 0;
    while (n != 0) {
        rev = rev * 10 + n % 10;
        n /= 10;
    }
    return rev;
}

bool isPalindromeNumber(int n) {
    return n == reverseNumber(n);
}

7. Armstrong number & GCD/LCM (C++)

cpp

bool isArmstrong(int n) {
    int original = n, sum = 0, digits = to_string(n).size();
    while (n > 0) {
        int d = n % 10;
        sum += pow(d, digits);
        n /= 10;
    }
    return sum == original;
}

int gcd(int a, int b) { return b == 0 ? a : gcd(b, a % b); }
int lcm(int a, int b) { return (a / gcd(a, b)) * b; }

8. Output tracing — increment/decrement (C++)

cpp

int x = 3, y = 4;
cout << x++ + ++y;
// Output: 8 -> old value of x (3) is used, y is incremented before use (5) -> 3+5=8

9. Kadane's maximum subarray (C++)

cpp

long long maxSubArraySum(vector<int>& a) {
    long long best = a[0], current = a[0];
    for (size_t i = 1; i < a.size(); i++) {
        current = max((long long)a[i], current + a[i]);
        best = max(best, current);
    }
    return best;
}

10. Prime check & sorting (Python)

cpp

def is_prime(n):
    if n < 2:
        return False
    for i in range(2, int(n ** 0.5) + 1):
        if n % i == 0:
            return False
    return True

def bubble_sort(arr):
    n = len(arr)
    for i in range(n):
        for j in range(n - i - 1):
            if arr[j] > arr[j + 1]:
                arr[j], arr[j + 1] = arr[j + 1], arr[j]
    return arr

Operating System Basics

Scheduling, deadlock and memory management essentials.

Process, threads & scheduling

  • • Process has its own memory space; threads share the memory of their parent process.
  • • Context switching between threads is cheaper than between processes.
  • • Scheduling algorithms: FCFS, SJF, SRTF, Round Robin, Priority (can cause starvation without ageing).

Deadlock & synchronisation

  • • Four necessary conditions: mutual exclusion, hold and wait, no preemption, circular wait.
  • • Mutex vs semaphore; race conditions from unsynchronised shared resources.
  • • Deadlock avoidance via Banker's Algorithm; detection via Resource Allocation Graph.

Memory management

  • • Paging uses fixed-size pages; segmentation uses variable-size logical segments.
  • • Virtual memory relies on demand paging and page replacement (FIFO, LRU, Optimal).
  • • User mode vs kernel mode; file systems basics.

Computer networks

  • • OSI 7 layers and TCP/IP model responsibilities.
  • • TCP (connection-oriented, reliable) vs UDP (connectionless, fast); three-way handshake.
  • • DNS resolution, HTTP/HTTPS, ARP, DHCP, MAC address, congestion control basics.
