How to Crack Wipro Interview in 2026: Complete Roadmap, Exam Pattern & Q&A

📅 Week 1 (Days 1–7): Aptitude Foundation

Revise quantitative basics (percentages, ratios, profit/loss, time-speed-distance). Solve 20 IndiaBix aptitude problems daily. Review syllogism rules and series completion patterns. Practice 2 reading comprehension passages daily.

📅 Week 2 (Days 8–14): DSA for Coding Round

Focus: Arrays, Strings, HashMaps, Two Pointers, Basic Recursion, Sorting algorithms. Solve 15 Easy LeetCode problems (tagged: Wipro, Array, String). Practice 1 coding problem daily on HackerEarth timed. Learn time complexity analysis — examiners look for O(n) over O(n²).

📅 Week 3 (Days 15–21): Core CS Subjects

OOPs: 4 pillars + polymorphism in detail. DBMS: normalization, joins, SQL queries (GROUP BY, HAVING, subqueries, window functions). OS: processes vs threads, deadlock, paging, scheduling algorithms. CN: OSI model, TCP vs UDP, HTTP vs HTTPS, DNS.

📅 Week 4 (Days 22–30): Mock Tests & Interview Prep

Take 3 full Wipro NLTH mock tests. Practice essay writing (2–3 essays). Rehearse answers to top 20 Wipro technical questions out loud. Practice HR answers using STAR method. Use Intervio's AI mock interview to simulate a Wipro technical + HR round and get scored feedback.

Q1. What are the 4 pillars of Object-Oriented Programming?

Q2. What is the difference between a process and a thread?

A process is an independent program in execution with its own memory space (heap, stack, code, data segments). A thread is the smallest unit of execution within a process — threads share memory space but have their own stack. Threads are lighter-weight (faster to create/switch) but require synchronization to avoid race conditions. One process can have multiple threads.

Q3. What is normalization in DBMS? Explain 1NF, 2NF, 3NF.

Q4. Write an SQL query to find the second highest salary.

-- Method 1: Subquery
SELECT MAX(salary) AS second_highest
FROM employees
WHERE salary < (SELECT MAX(salary) FROM employees);

-- Method 2: DENSE_RANK (handles ties correctly)
SELECT salary AS second_highest
FROM (
  SELECT salary, DENSE_RANK() OVER (ORDER BY salary DESC) AS rnk
  FROM employees
) ranked
WHERE rnk = 2
LIMIT 1;

Q5. What is a virtual function? What is pure virtual function?

A virtual function (in C++) is a member function in the base class declared with virtual keyword, which can be overridden in derived classes. It enables runtime polymorphism — the correct function is called based on the actual object type, not the pointer type. A pure virtual function has no implementation in the base class (virtual void fn() = 0), making the base class abstract and forcing all derived classes to implement it.

Q6. Explain the OSI model layers with examples.

Q7. What is deadlock? What are the 4 necessary conditions?

Deadlock is a state where two or more processes are permanently blocked, each waiting for a resource held by the other. The 4 Coffman conditions are: Mutual Exclusion (resource held by one process at a time), Hold and Wait (process holds resources while waiting for more), No Preemption (resources cannot be forcibly taken), Circular Wait (P1 waits for P2, P2 waits for P3, P3 waits for P1). Deadlock occurs only when ALL 4 are present simultaneously.

HR Q1. "Tell me about yourself."

Formula: [Degree + College] → [Strongest skill/project] → [Why Wipro] in 60–90 seconds.

HR Q2. "Why do you want to join Wipro?"

Focus on specifics — not just "good company". Mention: Wipro LEAP graduate program, WILP (Wipro-BITS Pilani dual degree), Wipro's focus on AI/cloud practices, global client exposure. Show you've researched the company.

HR Q3. "Where do you see yourself in 5 years?"

Answer: "In 5 years, I see myself as a senior software engineer at Wipro, having worked on multiple large-scale projects for global clients. I aim to develop expertise in [cloud/AI/backend] and eventually move into a technical lead role, mentoring junior engineers." Avoid "I want to start my own company" — it signals flight risk.

HR Q4. "Are you comfortable with service agreements and relocation?"

Wipro has a 1-year service agreement (bond) for freshers. Always answer: "Yes, I'm comfortable with both relocation and the service commitment. I understand Wipro invests in fresh engineers through training programs, and I'm committed to contributing value during this period."

Sample Easy: Reverse Words in a String

Input: "the sky is blue" → Output: "blue is sky the"

# Python solution
def reverseWords(s):
    return ' '.join(s.split()[::-1])

print(reverseWords("  the sky is blue  "))
# Output: "blue is sky the"

Sample Medium: Two Sum (HashMap approach)

Find indices of two numbers that add to target. Expected O(n) solution:

# Python - O(n) using HashMap
def twoSum(nums, target):
    seen = {}
    for i, num in enumerate(nums):
        complement = target - num
        if complement in seen:
            return [seen[complement], i]
        seen[num] = i

# Input: [2,7,11,15], target=9
# Output: [0, 1]
