Ellie Mae Software Engineer Interview Questions, Process, and Tips

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 ...read more
