InfyTQ Questions: Patterns and Worked Solutions for 2026

InfyTQ is Infosys’s certification exam that gates the two higher-paying fresher tracks: Specialist Programmer and Power Programmer. The standard placement path skips it entirely, but the package gap makes it worth understanding before your campus drive.

What InfyTQ Is and Which Tracks It Gates

Infosys runs three distinct fresher tracks, each with its own selection criteria and starting package:

Track	Starting CTC	Key qualifier	Typical CGPA
System Engineer (SE)	₹3.6 LPA	Infosys online test + technical + HR	60% / 6.0+
Specialist Programmer (SP)	₹6.5 LPA	Stronger online test + DSA focus + InfyTQ preferred	65%+
Power Programmer (PP)	₹9.5 LPA	Top InfyTQ or HackWithInfy + advanced technical + HR	7.5+

InfyTQ is a certification exam separate from the general campus placement test. You earn it before your placement window; the certification stays valid for one year from the date of passing. Infosys’s campus recruitment process draws SP and PP candidates primarily from the InfyTQ-certified pool. No certification, no consideration for either higher track at most drives.

The exam covers four areas: hands-on coding (Python or Java), SQL and DBMS concepts, aptitude and logical reasoning, and verbal ability. You choose your coding language at registration; both tracks test the same problem types. InfyTQ can be taken independently of any campus drive, which means third-year students can earn the certification well before their final-year placement window opens. Certification costs nothing to attempt via the official InfyTQ platform; the only investment is preparation time. Results are typically available within 24 to 48 hours of the exam.

InfyTQ Coding Questions: Python and Java Patterns

InfyTQ’s coding section is hands-on. You write, compile, and run actual code inside a browser IDE. Time complexity counts as much as correctness; an inefficient solution that passes small inputs may fail on the hidden test cases.

Second Largest Element in an Array

A recurring InfyTQ pattern. The constraint: no sorting allowed.

def second_largest(arr):
    first, second = float('-inf'), float('-inf')
    for num in arr:
        if num > first:
            second, first = first, num
        elif num > second and num != first:
            second = num
    return second if second != float('-inf') else "No second largest element"

arr = [10, 20, 4, 45, 99]
print("Second Largest Number:", second_largest(arr))

Trace through [10, 20, 4, 45, 99]:

• Start: first = -inf, second = -inf
• num = 10: greater than first, so second = -inf, first = 10
• num = 20: greater than first, so second = 10, first = 20
• num = 4: less than both. No change.
• num = 45: greater than first, so second = 20, first = 45
• num = 99: greater than first, so second = 45, first = 99
• Output: Second Largest Number: 45

Time complexity: O(n) (single pass, no extra space). This pattern appears in InfyTQ, HackWithInfy, and Infosys’s general coding rounds.

Check Whether a String is a Palindrome

Another high-frequency pattern for both Python and Java submissions:

def is_palindrome(s):
    s = s.lower().replace(" ", "")
    return s == s[::-1]

print(is_palindrome("racecar"))  # True
print(is_palindrome("hello"))    # False

s[::-1] reverses the string in one step. For Java submissions, use StringBuilder:

public static boolean isPalindrome(String s) {
    s = s.toLowerCase().replaceAll("\\s+", "");
    String reversed = new StringBuilder(s).reverse().toString();
    return s.equals(reversed);
}

Both return the same result. The logic is identical across languages; the syntax differs. If you registered for the Java track on InfyTQ, practise the StringBuilder pattern rather than converting Python mentally under exam pressure.

InfyTQ DBMS Questions: SQL and Database Concepts

DBMS questions in InfyTQ cover normalization, keys, joins, and SQL queries. The MCQ section tests conceptual understanding alongside syntax. One of the most-tested concept pairs is Primary Key vs. Unique Key.

Primary Key vs. Unique Key

Feature	Primary Key	Unique Key
Uniqueness	Required	Required
NULL values	Not allowed	One NULL permitted per column
Per-table count	One	Multiple
Primary purpose	Main record identifier	Uniqueness on non-identifier columns

Both constraints prevent duplicate values. The distinction: a primary key is the table’s main identifier and cannot be NULL; a unique key is a secondary uniqueness constraint and allows one NULL per column.

SQL implementation:

CREATE TABLE Students (
    StudentID   INT          PRIMARY KEY,
    Email       VARCHAR(50)  UNIQUE,
    Name        VARCHAR(50)
);

StudentID identifies each record and cannot be null. Email must be unique per student but can be absent for a newly registered record, so the DBMS allows one NULL. This distinction appears repeatedly in InfyTQ’s DBMS MCQ section.

A Common SQL Query Pattern

InfyTQ also tests SELECT queries with filtering and joins. A representative pattern:

SELECT Name, Email
FROM Students
WHERE StudentID > 100
ORDER BY Name ASC;

Concepts tested here: WHERE clause filtering, column selection, and ORDER BY sorting direction. Know the difference between WHERE (filters rows before grouping) and HAVING (filters groups after a GROUP BY has been applied). That distinction is a frequent InfyTQ MCQ. A secondary pattern to know: INNER JOIN returns only matching rows from both tables, while LEFT JOIN returns all rows from the left table and fills NULLs where the right table has no match.

InfyTQ Aptitude and Verbal Questions

Time and Work

• Given: A and B together complete a task in 10 days; A alone completes it in 15 days.
• A’s work rate: 1/15 of the task per day
• Combined work rate: 1/10 of the task per day
• B’s work rate: 1/10 minus 1/15 = 3/30 minus 2/30 = 1/30 per day
• B alone completes the task in 30 days

Number Series

A typical InfyTQ aptitude pattern:

• Series: 2, 6, 18, 54, 162, ?
• Rule: each term is the previous term multiplied by 3
• Next term: 162 multiplied by 3 = 486

Verbal Ability: Sentence Correction

InfyTQ’s verbal section tests grammar, sentence correction, and reading comprehension. A representative sentence-correction question:

• Given: “Each of the boys in the class are responsible for keeping their desk clean.”
• Error: “are” should be “is”
• Corrected: “Each of the boys in the class is responsible for keeping their desk clean.”
• Why: “Each” is a distributive pronoun that takes a singular verb regardless of the noun phrase that follows it. “Each of the boys” is grammatically equivalent to “each boy.”

InfyTQ and AI Skills: What Changes in 2026

Infosys’s CEO Salil Parekh, in Q4 FY26 earnings commentary, confirmed that the company is building a pool of forward-deployed engineers to do AI solution work directly with clients and that different starting compensation goes to candidates with AI-attuned skills. The company onboarded 20,000 freshers in FY26 and plans similar intake in FY27.

The Python and DBMS skills tested in InfyTQ sit at the base of that AI stack. Python is the runtime for most LLM integrations; SQL remains the primary interface for the data layers those systems depend on. Earning InfyTQ certification puts you in the SP-preferred or PP-eligible pool. Adding AI skills to the same foundation raises your relevance for the forward-deployed engineering track Infosys is actively building.
