Ellie Mae Interview Questions and Answers

Use binary search algorithm to find the given element in a sorted array.

• Start with the middle element of the array.

• If the middle element is equal to the given element, return its index.

• If the middle element is greater than the given element, search in the left half of the array.

• If the middle element is smaller than the given element, search in the right half of the array.

• Repeat the process until the element is found or...read more

Hoisting is a JavaScript mechanism where variables and function declarations are moved to the top of their scope.

• Hoisting applies to variable and function declarations, but not to variable assignments

• Function declarations are hoisted before variable declarations

• Hoisting can lead to unexpected behavior and should be avoided

Specificity in CSS refers to the priority given to different CSS rules when multiple rules apply to the same element.

• Specificity is determined by the number of ID, class, and element selectors in a rule

• Pseudo selectors like :hover and :active can also affect specificity

• Using !important can override specificity, but should be used sparingly

• Understanding specificity is important for avoiding unexpected styling conflicts

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...read more

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.

• 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
