Top Microsoft Interview Questions<\/h2>

Microsoft interviews focus on core computer science fundamentals, coding efficiency, system design, and problem-solving. Below are some of the most common technical questions asked to candidates.<\/p>

1. Technical Questions<\/h3>
\n
    \n
  1. What is the difference between an abstract class and an interface in C#?<\/strong>
    \nAn abstract class can provide both definitions and implementations, while an interface only provides method signatures.<\/li>\n
  2. How would you reverse a linked list in place?<\/strong>
    \nBy iterating through nodes and changing next pointers, using constant space and O(n) time complexity.<\/li>\n
  3. Explain garbage collection in .NET.<\/strong>
    \nGarbage collection automatically manages memory by reclaiming objects no longer in use, preventing memory leaks.<\/li>\n
  4. How do you detect a cycle in a directed graph?<\/strong>
    \nUse depth-first search with a recursion stack or Kahn’s algorithm for topological sorting.<\/li>\n
  5. What is the difference between managed and unmanaged code?<\/strong>
    \nManaged code runs under the .NET CLR, while unmanaged code runs directly on the OS without CLR support.<\/li>\n
  6. How would you implement a LRU cache?<\/strong>
    \nBy combining a doubly linked list with a hash map to achieve O(1) insertion and retrieval.<\/li>\n
  7. What are delegates in C#?<\/strong>
    \nDelegates are type-safe function pointers used for event handling and callback methods.<\/li>\n
  8. How do you handle database deadlocks?<\/strong>
    \nBy using transaction isolation levels, deadlock detection, retry logic, or breaking long transactions into smaller ones.<\/li>\n
  9. What is multithreading and how is it handled in C#?<\/strong>
    \nMultithreading enables concurrent execution using Thread, Task, and async\/await patterns in C#.<\/li>\n
  10. How would you design a URL shortener like bit.ly?<\/strong>
    \nUse hash functions or base62 encoding, database sharding for scalability, and caching for fast retrieval.<\/li>\n
  11. Explain dependency injection in .NET Core.<\/strong>
    \nDependency injection provides loose coupling by supplying required dependencies at runtime rather than hardcoding them.<\/li>\n
  12. What is the difference between value type and reference type in C#?<\/strong>
    \nValue types store data directly in memory, while reference types store memory addresses pointing to data.<\/li>\n
  13. How would you test the performance of a REST API?<\/strong>
    \nUse load testing tools like JMeter or Apache Bench, monitor latency, throughput, and error rates under stress.<\/li>\n
  14. What are design patterns you commonly use?<\/strong>
    \nExamples include Singleton for global state, Factory for object creation, and Observer for event-driven programming.<\/li>\n
  15. How do you optimize SQL queries in a large-scale database?<\/strong>
    \nBy creating indexes, analyzing execution plans, normalizing tables, and reducing unnecessary joins.<\/li>\n<\/ol>\n<\/div><\/div>

    2. Role-Based Questions<\/h3>
    \n

    Fresher \/ Intern Roles<\/strong><\/p>\n

      \n
    1. What is the difference between stack and queue?<\/strong>
      \nStack follows LIFO, while queue follows FIFO for element access.<\/li>\n
    2. How would you check if a string is a palindrome in C#?<\/strong>
      \nBy comparing characters from both ends moving inward, or by reversing the string and checking equality.<\/li>\n
    3. What are the pillars of Object-Oriented Programming?<\/strong>
      \nEncapsulation, Abstraction, Inheritance, and Polymorphism.<\/li>\n<\/ol>\n

      Software Engineer \/ Developer Roles<\/strong><\/p>\n

        \n

      2. What is the difference between SQL Server and Azure SQL Database?<\/strong>
        \nSQL Server is an on-premise solution, while Azure SQL is a managed cloud service with built-in scaling and security.<\/li>\n
      3. How do you debug a memory leak in a .NET application?<\/strong>
        \nBy using tools like Visual Studio Profiler or dotMemory to analyze heap allocations and uncollected objects.<\/li>\n
      4. How would you handle real-time data streaming in Azure?<\/strong>
        \nBy using Azure Event Hubs, Stream Analytics, and Azure Functions for ingestion, processing, and storage.<\/li>\n
      5. What is the difference between Azure Functions and Azure Logic Apps?<\/strong>
        \nAzure<\/a> Functions focus on serverless code execution, while Logic Apps focus on workflow automation with minimal coding.<\/li>\n<\/ol>\n
