I applied via Naukri.com and was interviewed in Oct 2020. There were 4 interview rounds.
Memory management in .NET involves automatic garbage collection and allocation of memory for objects.
Garbage collector automatically frees memory for objects that are no longer in use
Memory allocation is done by the Common Language Runtime (CLR)
CLR uses a heap to allocate memory for objects
Memory leaks can occur if objects are not properly disposed of
Managed code is protected from buffer overflows and other memory-rela...
WebAPI is a set of protocols and tools for building web applications and services.
WebAPI allows communication between different software systems over the internet.
It uses HTTP requests and responses to exchange data.
WebAPIs can be used to retrieve data, update data, or perform other operations.
Examples of WebAPIs include the Twitter API, the Google Maps API, and the Facebook Graph API.
Put and Patch are HTTP methods used to update resources. Put replaces the entire resource while Patch updates only the specified fields.
Put is used to completely replace an existing resource with a new one
Patch is used to update only the specified fields of an existing resource
Put requires the entire resource to be sent in the request body
Patch requires only the fields to be updated to be sent in the request body
L stands for Liskov Substitution Principle in SOLID
Liskov Substitution Principle states that objects of a superclass should be able to be replaced with objects of its subclass without affecting the correctness of the program
This principle ensures that the behavior of the program remains consistent when new classes are added
Violating this principle can lead to unexpected behavior and bugs in the program
Parallel programming in C# allows multiple tasks to be executed simultaneously for improved performance.
Parallel programming can be achieved using the Task Parallel Library (TPL) in C#.
TPL provides constructs like Parallel.For and Parallel.ForEach to execute loops in parallel.
Parallel.Invoke can be used to execute multiple methods in parallel.
Data parallelism can be achieved using PLINQ (Parallel LINQ) to execute LINQ ...

To debug a particular program without affecting others, use breakpoints and step through the code.
Set a breakpoint in the program you want to debug
Step through the code using a debugger to identify the issue
Use logging statements to track the flow of the program
Check the call stack to see which functions are being called
Use conditional breakpoints to stop the program at specific points
I applied via Campus Placement and was interviewed before Feb 2020. There were 4 interview rounds.
If and Switch Case statements are used for conditional branching in programming.
If statements are used for simple conditional branching.
Switch Case statements are used for multiple conditional branching.
If statements are more flexible than Switch Case statements.
Switch Case statements are more efficient than If statements for large number of conditions.
If statements can be nested, but Switch Case statements cannot.

Yes, algorithms and pseudocodes are still important in IT Services.
Algorithms are used in various fields of IT such as machine learning, data analysis, and cryptography.
Pseudocodes are used to plan and design algorithms before coding them.
Understanding algorithms and pseudocodes is essential for software engineers to write efficient and optimized code.
Examples of algorithms include sorting algorithms, search algorithms...
Yes, I am comfortable using both CLIs and IDEs for my daily tasks.
I have experience using various CLIs such as Git Bash, Windows Command Prompt, and Terminal on macOS.
I am proficient in using IDEs such as Visual Studio Code, Eclipse, and IntelliJ IDEA.
I understand the benefits and drawbacks of both CLIs and IDEs and can choose the appropriate tool for the task at hand.
I applied via Campus Placement and was interviewed in Nov 2020. There were 6 interview rounds.
OOPs concepts are the fundamental principles of object-oriented programming.
Encapsulation - binding data and functions that manipulate the data
Inheritance - creating new classes from existing ones
Polymorphism - ability of objects to take on many forms
Abstraction - hiding implementation details and showing only functionality
Storage classes in C define the scope and lifetime of variables.
There are four storage classes in C: auto, register, static, and extern.
Auto variables are local to a block and have automatic storage duration.
Register variables are stored in CPU registers for faster access.
Static variables have a lifetime throughout the program and are initialized only once.
Extern variables are declared outside any function and can be a...
Linked list is a linear data structure. DFS and BFS are graph traversal algorithms.
Linked list is a collection of nodes where each node points to the next node.
DFS (Depth First Search) is a traversal algorithm that explores as far as possible along each branch before backtracking.
BFS (Breadth First Search) is a traversal algorithm that explores all the vertices of a graph in breadth-first order.
Example of linked list: ...
Optimize O(n2) program to O(log n)
Use binary search instead of linear search
Divide and conquer approach can be used
Implement efficient data structures like heap, AVL tree, etc.
Reduce unnecessary iterations and comparisons
Use memoization to avoid redundant calculations
