E-Sharp is a high-level computer programming language developed by Microsoft for its .NET framework. First introduced in 2001, it was designed to simplify the development process of web applications and services. E-Sharp is renowned for its simplicity and ease of use, making it an ideal choice for beginners in programming. It also boasts robust features that appeal to seasoned developers, including strong typing, array bounds checking, and automatic garbage collection. This information can be found on Microsoft's official documentation and various reputable tech-based online platforms such as Stack Overflow or Techopedia.

First 20 minutes

General E-Sharp app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in E-Sharp application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

How would you define E-Sharp?

E-Sharp is a programming language that is a subset of C# and is designed for embedded systems.

What are the main features of E-Sharp?

E-Sharp includes features such as strong typing, garbage collection, and support for object-oriented programming.

Describe the difference between E-Sharp and C#.

E-Sharp is a subset of C# specifically for embedded systems. It lacks some features of C# like unsafe code and some advanced features like reflection.

How would you handle exceptions in E-Sharp?

E-Sharp supports exception handling similar to C#. You can use try, catch, and finally blocks to handle exceptions.

What are the data types supported by E-Sharp?

E-Sharp supports a variety of data types, including integral types, floating-point types, decimal type, Boolean type, string type, and object type.

Can the candidate communicate clearly and effectively?

Does the candidate show an ability to work well in a team?

Next 20 minutes

Specific E-Sharp development questions

The next 20 minutes of the interview should focus on the candidate's expertise with specific backend frameworks, their understanding of RESTful APIs, and their experience in handling data storage and retrieval efficiently.

How would you create a class in E-Sharp?

You can create a class in E-Sharp using the 'class' keyword followed by the class name and a pair of curly braces that contain the class members.

Describe the difference between a struct and a class in E-Sharp.

In E-Sharp, a struct is a value type while a class is a reference type. Also, a struct does not support inheritance while a class does.

How would you implement polymorphism in E-Sharp?

You can implement polymorphism in E-Sharp by creating a base class and derived classes. The base class defines a method that can be overridden by the derived classes.

What are the access modifiers in E-Sharp?

E-Sharp supports four access modifiers: public, protected, internal, and private.

How would you create an interface in E-Sharp?

You can create an interface in E-Sharp using the 'interface' keyword followed by the interface name and a pair of curly braces that contain the interface members.

Oops! Something went wrong while submitting the form.

At this point, a skilled E-Sharp engineer should demonstrate strong problem-solving abilities, proficiency in E-Sharp programming language, and knowledge of software development methodologies. Red flags include lack of hands-on experience, inability to articulate complex concepts, or unfamiliarity with standard coding practices.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with E-Sharp.

What does the following E-Sharp code do?
var x = 5;
var y = 10;
var z = x + y;
Console.WriteLine(z);
The code declares two integer variables x and y, assigns them the values 5 and 10 respectively, then adds these two values together and assigns the result to a third variable z. Finally, it prints the value of z, which is 15, to the console.
What will be the output of the following E-Sharp code?
var a = 'Hello';
var b = 'World';
var c = a + ' ' + b;
Console.WriteLine(c);
The code concatenates the string variables a and b with a space in between and assigns the result to a third variable c. It then prints the value of c, which is 'Hello World', to the console.
What does the following E-Sharp code do?
var nums = new[] { 1, 2, 3, 4, 5 };
var sum = 0;
foreach (var num in nums) {
  sum += num;
}
Console.WriteLine(sum);
The code declares an array of integers and initializes it with the numbers 1 through 5. It then declares an integer variable sum and initializes it to 0. It uses a foreach loop to iterate over the array, adding each number to sum. Finally, it prints the value of sum, which is the sum of the numbers in the array, to the console.
What does the following E-Sharp code do?
var t1 = new Thread(() => {
  for (var i = 0; i < 10; i++) {
    Console.WriteLine(i);
  }
});
t1.Start();
The code creates a new thread t1 and assigns it a lambda expression that prints the numbers 0 through 9 to the console. It then starts the thread. The numbers will be printed in a separate thread from the main thread.

Wrap-up questions

Final candidate for E-Sharp Developer role questions

The final few questions should evaluate the candidate's teamwork, communication, and problem-solving skills. Additionally, assess their knowledge of microservices architecture, serverless computing, and how they handle E-Sharp application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

Describe the difference between an abstract class and an interface in E-Sharp.

In E-Sharp, an abstract class can provide implementation for some of its members, but an interface cannot. Also, a class can implement multiple interfaces but can only inherit from one abstract class.

How would you handle memory management in E-Sharp?

E-Sharp has a garbage collector that automatically manages memory. However, you can also use the 'using' statement to ensure that resources are released when they are no longer needed.

What are the differences between value types and reference types in E-Sharp?

In E-Sharp, value types are stored in the stack and hold their actual values, while reference types are stored in the heap and hold a reference to their values.
