Technical Interview Questions with Answers

Q1: What is Cloud Computing? Explain its service models.

Service Models:

IaaS (Infrastructure as a Service): Provides basic building blocks - servers, storage, networking. User manages OS, middleware, runtime, data, and applications.

Examples: AWS EC2, Microsoft Azure VMs, Google Compute Engine
Use case: Startups needing flexible infrastructure

PaaS (Platform as a Service): Provides platform to develop, run, and manage applications without infrastructure management.

Examples: Heroku, Google App Engine, AWS Elastic Beanstalk
Use case: Developers focusing on code, not infrastructure

SaaS (Software as a Service): Complete software applications managed by vendor.

Examples: Gmail, Salesforce, Microsoft 365
Use case: End users accessing software via browser

Benefits: Cost reduction, scalability, global reach, reliability, and faster innovation."

Q2: Write a program to find the longest common subsequence.

def longest_common_subsequence(text1, text2):
    m, n = len(text1), len(text2)
    
    # Create DP table
    dp = [[0] * (n + 1) for _ in range(m + 1)]
    
    # Fill the table
    for i in range(1, m + 1):
        for j in range(1, n + 1):
            if text1[i-1] == text2[j-1]:
                dp[i][j] = dp[i-1][j-1] + 1
            else:
                dp[i][j] = max(dp[i-1][j], dp[i][j-1])
    
    # Backtrack to find the sequence
    lcs = []
    i, j = m, n
    while i > 0 and j > 0:
        if text1[i-1] == text2[j-1]:
            lcs.append(text1[i-1])
            i -= 1
            j -= 1
        elif dp[i-1][j] > dp[i][j-1]:
            i -= 1
        else:
            j -= 1
    
    return ''.join(reversed(lcs))

# Test
print(longest_common_subsequence("ABCDE", "ACE"))  # Output: ACE

Time Complexity: O(m×n), Space Complexity: O(m×n)

Q3: Explain the concept of Microservices architecture.

Key Characteristics:

Single Responsibility: Each service does one thing well
Independence: Services can be developed, deployed, and scaled independently
Decentralized Data: Each service manages its own database
API Communication: HTTP/REST, gRPC, or message queues
Technology Diversity: Different services can use different tech stacks

Advantages:

Scalability: Scale only the services that need it
Fault Isolation: One service failing doesn't crash others
Technology Flexibility: Use best tool for each job
Team Autonomy: Small teams own services end-to-end
Easier Maintenance: Smaller, manageable codebases

Challenges:

Distributed system complexity
Data consistency across services
Network latency
Operational overhead

Tools: Kubernetes for orchestration, Docker for containerization, Istio for service mesh."

Q4: What is the difference between SQL and NoSQL databases? When would you use each?

Structured data with predefined schema
ACID compliance (Atomicity, Consistency, Isolation, Durability)
Vertical scaling (bigger servers)
Complex queries with JOINs
Examples: MySQL, PostgreSQL, Oracle
Use when: Data integrity is critical, complex relationships, structured data, transactions needed (banking, ERP)

NoSQL (Non-Relational):

Flexible schema or schema-less
BASE properties (Basically Available, Soft state, Eventual consistency)
Horizontal scaling (more servers)
Simple queries, limited JOINs
Types: Document (MongoDB), Key-Value (Redis), Column (Cassandra), Graph (Neo4j)
Use when: Rapid development, big data, real-time applications, unstructured/semi-structured data (social media, IoT, content management)

Modern Approach: Many applications use both - SQL for transactional data, NoSQL for analytics, caching, and logs."

Q5: Write a SQL query to find duplicate records in a table.

-- Find duplicates based on email
SELECT email, COUNT(*) as duplicate_count
FROM users
GROUP BY email
HAVING COUNT(*) > 1;

-- Find all columns for duplicate records
SELECT u1.*
FROM users u1
JOIN (
    SELECT email
    FROM users
    GROUP BY email
    HAVING COUNT(*) > 1
) u2 ON u1.email = u2.email
ORDER BY u1.email;

-- Delete duplicates keeping the one with minimum ID
DELETE u1 FROM users u1
INNER JOIN users u2
WHERE u1.id > u2.id AND u1.email = u2.email;

-- Using ROW_NUMBER() to identify duplicates (SQL Server/PostgreSQL)
WITH RankedUsers AS (
    SELECT *,
        ROW_NUMBER() OVER (PARTITION BY email ORDER BY id) as rn
    FROM users
)
SELECT * FROM RankedUsers WHERE rn > 1;

The HAVING clause filters groups, unlike WHERE which filters rows. Always backup before deleting duplicates.

Q6: Explain CI/CD pipeline and its importance.

Continuous Integration (CI):

Developers frequently merge code changes to central repository
Automated builds and tests run on each commit
Catches integration issues early
Tools: Jenkins, GitHub Actions, GitLab CI, CircleCI

Continuous Delivery (CD):

Automatically deploys code to testing/staging environments
Ensures code is always in deployable state
Manual approval for production deployment

Continuous Deployment:

Automatically deploys passing builds to production
No manual intervention
Requires comprehensive test coverage

Pipeline Stages:

Code commit triggers pipeline
Build - compile code, create artifacts
Unit Testing - run automated tests
Integration Testing - test component interactions
Security Scanning - vulnerability checks
Deployment - to staging/production

Benefits: Faster releases, reduced manual errors, early bug detection, consistent process, faster feedback."

Q7: What are Design Patterns? Explain Singleton and Factory patterns.

Singleton Pattern: Ensures a class has only one instance and provides global access to it.

public class Singleton {
    private static Singleton instance;
    
    private Singleton() {} // Private constructor
    
    public static Singleton getInstance() {
        if (instance == null) {
            instance = new Singleton();
        }
        return instance;
    }
}

Use cases: Database connections, logging services, configuration managers.

Factory Pattern: Creates objects without specifying exact class, delegating instantiation to subclasses.

interface Shape { void draw(); }

class ShapeFactory {
    public Shape getShape(String type) {
        if (type.equals("CIRCLE")) return new Circle();
        if (type.equals("RECTANGLE")) return new Rectangle();
        return null;
    }
}

Use cases: When object creation logic is complex, need flexibility in object creation.

Other Important Patterns: Observer, Strategy, MVC, Decorator, Adapter."

Q8: Write a function to detect a cycle in a linked list.

class ListNode:
    def __init__(self, val=0):
        self.val = val
        self.next = None

def has_cycle(head):
    """Floyd's Cycle-Finding Algorithm (Tortoise and Hare)"""
    if not head or not head.next:
        return False
    
    slow = head  # Tortoise - moves 1 step
    fast = head.next  # Hare - moves 2 steps
    
    while fast and fast.next:
        if slow == fast:
            return True  # Cycle detected
        slow = slow.next
        fast = fast.next.next
    
    return False  # No cycle

def find_cycle_start(head):
    """Find the start node of the cycle"""
    if not has_cycle(head):
        return None
    
    # Reset slow to head, keep fast at meeting point
    slow = head
    fast = head
    
    # Move both one step until they meet
    while fast.next != slow:
        slow = slow.next
        fast = fast.next
    
    return slow

Time Complexity: O(n), Space Complexity: O(1) - optimal solution.

Q9: Explain Authentication vs Authorization.

Proves identity
"Are you who you say you are?"
Methods: Passwords, biometrics, OTPs, tokens, certificates
Examples: Login with username/password, fingerprint scan, 2FA

Authorization (AuthZ): Determining what you can do.

Grants permissions
"What are you allowed to do?"
Methods: Access Control Lists (ACLs), Role-Based Access Control (RBAC), policies
Examples: Admin can delete users, regular user can only view

Relationship: Authentication always comes first. You must prove identity before permissions are checked.

Implementation:

Authentication: JWT tokens, OAuth, SAML, LDAP
Authorization: OAuth scopes, RBAC, ABAC (Attribute-Based)

Real-world Example:

Show ID at building entrance (Authentication)
ID card allows access to floor 3 but not floor 5 (Authorization)

Security Best Practices: Use strong authentication (MFA), principle of least privilege for authorization, regular access reviews."

Q10: What is Docker and how does it differ from Virtual Machines?

Docker Architecture:

Docker Engine: Runtime environment
Docker Images: Read-only templates
Docker Containers: Runnable instances of images
Docker Hub: Registry for sharing images

Docker vs Virtual Machines:

Feature	Docker Containers	Virtual Machines
OS	Shares host OS kernel	Each has full OS
Size	Lightweight (MBs)	Heavy (GBs)
Startup	Seconds	Minutes
Performance	Near native	Slower (hypervisor overhead)
Isolation	Process-level	Hardware-level
Portability	Highly portable	Less portable
Resource Usage	Efficient	Resource intensive

Benefits of Docker:

Consistent environments (dev, test, prod)
Easy scaling and orchestration (Kubernetes)
Faster deployment
Efficient resource utilization
Microservices architecture support

Docker Commands: docker build, docker run, docker ps, docker stop, docker-compose."
