Aptitude Questions

1. If 12 men can reap 120 acres in 36 days, how many acres can 54 men reap in 54 days?

Solution: Using M1×D1/W1 = M2×D2/W2 12×36/120 = 54×54/W2 W2 = 54×54×120/(12×36) = 810 acres

2. Find the sum: 1 + 2 + 3 + ... + 50

Solution: Sum = n(n+1)/2 = 50×51/2 = 1275

3. A sum amounts to ₹6050 in 2 years and ₹6655 in 3 years at CI. Find rate.

Solution: Interest in 1 year = 6655 - 6050 = ₹605 Rate = 605/6050 × 100 = 10%

4. A and B together complete work in 12 days. A alone in 20 days. How long for B alone?

Solution: 1/A + 1/B = 1/12 1/20 + 1/B = 1/12 1/B = 1/12 - 1/20 = (5-3)/60 = 2/60 = 1/30 B = 30 days

5. Find next: 1, 4, 9, 16, 25, ?

Solution: Perfect squares: 1², 2², 3², 4², 5² Next = 6² = 36

6. Average of 5 numbers is 20. If one number excluded, average becomes 18. Find excluded number.

Solution: Sum of 5 = 20 × 5 = 100 Sum of 4 = 18 × 4 = 72 Excluded = 100 - 72 = 28

7. Ratio of present ages of A and B is 4:5. After 5 years, ratio becomes 5:6. Find B's present age.

Solution: Let ages be 4x and 5x (4x+5)/(5x+5) = 5/6 24x + 30 = 25x + 25 x = 5 B's age = 5 × 5 = 25 years

8. A boat covers 16 km downstream in 2 hours and same distance upstream in 4 hours. Find stream speed.

Solution: Downstream speed = 16/2 = 8 km/hr Upstream speed = 16/4 = 4 km/hr Stream speed = (8-4)/2 = 2 km/hr

9. Probability of getting at least one head when 3 coins are tossed.

Solution: P(at least 1 head) = 1 - P(all tails) = 1 - (1/2)³ = 1 - 1/8 = 7/8

10. How many factors does 72 have?

Solution: 72 = 2³ × 3² Number of factors = (3+1)(2+1) = 4×3 = 12

Coding Questions

1. Find the second largest element in array.

def second_largest(arr):
    if len(arr) < 2:
        return None
    
    first = second = 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 None

# Test
print(second_largest([10, 20, 4, 45, 99]))  # 45

2. Check if two strings are anagrams.

def are_anagrams(s1, s2):
    return sorted(s1) == sorted(s2)

# Or using Counter
from collections import Counter
def are_anagrams_counter(s1, s2):
    return Counter(s1) == Counter(s2)

# Test
print(are_anagrams("listen", "silent"))  # True

3. Implement binary search.

def binary_search(arr, target):
    left, right = 0, len(arr) - 1
    
    while left <= right:
        mid = (left + right) // 2
        if arr[mid] == target:
            return mid
        elif arr[mid] < target:
            left = mid + 1
        else:
            right = mid - 1
    
    return -1

# Test
print(binary_search([1, 3, 5, 7, 9], 5))  # 2

4. Find all pairs in array with given sum.

def find_pairs(arr, target):
    seen = set()
    pairs = []
    
    for num in arr:
        complement = target - num
        if complement in seen:
            pairs.append((complement, num))
        seen.add(num)
    
    return pairs

Frequently Asked Questions

What is the typical salary range for Informatica placements in 2026?

Informatica’s offers for 2026 generally fall in the mid-to-high range for data engineering, integration, and cloud data roles, with compensation varying by location, role, and candidate profile. For many campus hires, the CTC is commonly seen in the range of ~₹8 LPA to ₹20 LPA, but top performers with strong projects and interview performance can go higher.

What are the eligibility criteria for Informatica campus placements?

Most Informatica drives expect candidates from eligible B.Tech/B.E./MCA/M.Sc. programs with a consistent academic record and relevant coursework in computer science, data structures, databases, or software engineering. Some drives also specify a minimum percentage/CGPA and may restrict backlogs or require graduation by a certain month in 2026.

How difficult are Informatica placement papers and interviews?

The difficulty is usually moderate to high because the process tests both fundamentals (DSA, DBMS, SQL) and role-specific skills (data integration, ETL concepts, data quality, and cloud basics). Candidates who have only memorized theory often struggle, while those who can solve coding problems and explain data workflows clearly tend to perform better.

What preparation tips work best for Informatica placement 2026?

Focus on strong SQL practice (joins, window functions, query optimization basics) and revise core DBMS concepts like normalization, indexing, transactions, and constraints. Alongside this, prepare coding with common patterns (arrays/strings, hashing, stacks/queues, graphs basics) and build at least one project demonstrating ETL/data integration or data quality checks.

What are the interview rounds in the Informatica selection process?

A typical process includes an online assessment followed by technical rounds and then an HR round. Technical interviews often cover coding/DSA, SQL/DBMS, and scenario-based questions on data integration, data governance, or troubleshooting data pipelines.

What common topics appear in Informatica placement papers?

Common topics include SQL (joins, subqueries, aggregations, window functions), DBMS (ER modeling, normalization, indexing, transactions), and data engineering fundamentals like ETL/ELT, data lineage, and data quality dimensions. Coding rounds frequently include standard DSA problems, while aptitude may test reasoning and basic quantitative logic.

How do I apply for Informatica placements for 2026?

You typically apply through your college’s placement portal or the company’s official campus recruitment listing, if available. Ensure your resume highlights relevant skills (SQL, ETL, data integration tools, cloud basics) and that your projects clearly map to the role you’re targeting.

What is the selection rate for Informatica placements, and how can I improve my chances?

The selection rate varies by campus and year, but it is generally competitive because the process filters for both aptitude and strong technical fundamentals. To improve your chances, aim for high accuracy in the online assessment, practice SQL daily, prepare 2–3 strong data-related projects, and be ready to explain your approach clearly during technical interviews.
