EGL# (Embedded Graphics Library) is a procedural programming language created by Sun Microsystems in the early 1990s. It was designed specifically for embedded systems development, and is based on the C programming language. EGL# is still in use today, and is supported by a number of compilers and development tools.

First 20 minutes

General EGL# app knowledge and experience

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

How would you define EGL#?

EGL# is a high-level, general-purpose programming language that is part of the EGL (Enterprise Generation Language) family. It is designed for building modern, multi-platform applications.

What are the key features of EGL#?

Key features of EGL# include its simplicity, strong typing, support for object-oriented programming, and its ability to generate code in multiple target languages.

Describe the difference between static and dynamic typing in EGL#.

In static typing, the type of a variable is known at compile time. In dynamic typing, the type is known at runtime. EGL# is a statically typed language.

How would you handle exceptions in EGL#?

In EGL#, exceptions are handled using try-catch blocks. The 'try' block contains the code that might throw an exception, and the 'catch' block contains the code to execute if an exception occurs.

What are the different types of loops in EGL#?

EGL# supports various types of loops, including 'for' loops, 'while' loops, and 'do-while' loops.

Next 20 minutes

Specific EGL# 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.

Describe the difference between a class and an interface in EGL#.

A class is a blueprint for creating objects and can contain fields, methods, and constructors. An interface is a reference type and contains only the signatures of methods, properties, events or indexers.

How would you define a method in EGL#?

In EGL#, a method is defined using the 'function' keyword, followed by the method name, a pair of parentheses, and a block of code enclosed in curly braces.

What are the access modifiers in EGL#?

EGL# supports several access modifiers, including 'public', 'private', and 'protected', which control the visibility of classes, methods, and other members.

Describe the difference between overloading and overriding in EGL#.

Overloading is when multiple methods in the same class have the same name but different parameters. Overriding is when a child class redefines a method from its parent class.

How would you use inheritance in EGL#?

In EGL#, inheritance is implemented using the 'extends' keyword. The child class inherits all the public and protected members of the parent class.

Oops! Something went wrong while submitting the form.

At this point, a skilled EGL# engineer should demonstrate strong problem-solving abilities, proficiency in EGL# 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 EGL#.

What does this simple EGL code do?
function add(a int, b int) returns(int)
  return a + b;
end
This code defines a function called 'add' that takes two integer parameters, adds them together, and returns the result.
What is the output of this EGL code snippet?
string name = "John Doe";
SysLib.writeStdout(name);
This code will print 'John Doe' to the standard output.
What does this EGL code do with an array?
function reverseArray(arr []int) returns([]int)
  return arr.reverse();
end
This function takes an array of integers as input, reverses the order of the elements in the array, and returns the reversed array.
What does this EGL code do related to threading?
Thread thread = new Thread();
thread.start(new Runnable(){
  public void run() {
    SysLib.writeStdout("Hello, World!");
  }
});
This code creates a new thread and starts it. The new thread will execute the code inside the run() method, which prints 'Hello, World!' to the standard output.

Wrap-up questions

Final candidate for EGL# 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 EGL# application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

What are the different types of collections in EGL#?

EGL# supports various types of collections, including arrays, lists, sets, and maps.

Describe the difference between an array and a list in EGL#.

An array is a fixed-size collection of elements of the same type. A list is a dynamic-size collection that can grow or shrink as needed.

How would you implement multithreading in EGL#?

In EGL#, multithreading can be implemented using the 'Thread' class. Each thread runs independently and can execute code concurrently with other threads.
