DRAKON-C# Developer Hiring Guide

Hiring Guide for DRAKON-C# Engineers

Ask the right questions to secure the right DRAKON-C# talent among an increasingly shrinking pool of talent.

DRAKON-C# is a programming language that is a variant of the C# language, designed to be used with the DRAKON visual programming language. DRAKON is a visual language for specifications from the Russian space program, which aims to represent complex logic in a way that is easy to understand and less prone to errors. DRAKON-C# combines this visual clarity with the power and flexibility of C#, allowing developers to write code that is both efficient and easy to read. It's especially useful for complex algorithms and logic flows, as it helps to visualize the flow of control and data within the program.

First 20 minutes

General DRAKON-C# knowledge and experience

The next 20 minutes of the interview should attempt to focus more specifically on the development questions used, and the level of depth and skill the engineer possesses.

Describe the difference between DRAKON and traditional flowcharts.

DRAKON is more structured and consistent than traditional flowcharts. It has specific rules and principles that make it easier to understand and follow. Traditional flowcharts can be more flexible, but they can also be more confusing and harder to follow.

What are the benefits of using DRAKON-C#?

DRAKON-C# allows developers to visually represent complex logic, making it easier to understand and follow. It also helps in documenting the system, making it easier for other developers to understand the code.

How would you integrate DRAKON with C#?

DRAKON can be integrated with C# using the DRAKON Editor. This tool allows you to create DRAKON diagrams and generate C# code from them.

What are the main principles of DRAKON?

The main principles of DRAKON are clarity, simplicity, and consistency. It aims to reduce cognitive load for the developer, making it easier to understand and follow complex logic.

How would you describe the DRAKON language?

DRAKON is a visual language for specifications from the Russian space program. It's designed to represent complex logic and algorithms in a way that's easy to understand and follow. It's particularly useful for designing and documenting software systems.

How familiar is the candidate with software development methodologies?

Understanding methodologies such as Agile or Scrum can be beneficial for workflow management and team collaboration.

Does the candidate have experience with other programming languages?

While DRAKON-C# is the focus, having experience with other languages can provide a broader understanding of programming concepts and can be beneficial in certain situations.

Did they show problem-solving skills during the technical test?

The ability to solve problems is crucial in a developer role, as they will often need to find solutions to complex coding issues.

Has the candidate demonstrated a strong understanding of DRAKON-C#?

This is important because the candidate needs to be able to understand and use DRAKON-C# effectively in order to perform well in the position.

Next 20 minutes

Specific DRAKON-C# development questions

The next 20 minutes of the interview should attempt to focus more specifically on the development questions used, and the level of depth and skill the engineer possesses.

What are the rules for creating a DRAKON diagram?

There are several rules for creating a DRAKON diagram, including the 'one entry, one exit' rule, the 'no lines crossing' rule, and the 'downward flow' rule. These rules help ensure that the diagram is clear and easy to follow.

How would you represent a loop in DRAKON?

In DRAKON, a loop can be represented using the 'For Each' or 'While' icons. These icons allow you to specify a condition and a block of code that should be repeated as long as the condition is true.

Describe the difference between the 'Question' and 'Choice' icons in DRAKON.

The 'Question' icon in DRAKON is used to represent a condition or decision point. The 'Choice' icon is used to represent a selection from multiple options.

What are the different types of icons in DRAKON?

DRAKON has several types of icons, including Action, Question, Choice, Address, and End. Each icon has a specific meaning and use in the diagram.

How would you handle errors in DRAKON-C#?

In DRAKON-C#, errors can be handled using the 'Try-Catch-Finally' icon. This allows you to specify what should happen if an error occurs, and what should happen regardless of whether an error occurs.

The ideal back-end app developer

What you’re looking to see on the DRAKON-C# engineer at this point.

At this point, a skilled DRAKON-C# engineer should have demonstrated strong proficiency in C# programming, deep understanding of DRAKON visual language, and problem-solving abilities. Red flags would include lack of knowledge about syntax or difficulty explaining complex algorithms using DRAKON flowcharts.

Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with DRAKON-C#.

What does the following DRAKON-C# code do?

var x = 5;
var y = 10;
var z = x + y;
Console.WriteLine(z);

This code declares two integer variables x and y, assigns them the values 5 and 10 respectively, adds them together and assigns the result to a new variable z. It then outputs the value of z, which would be 15, to the console.

What will be the output of the following DRAKON-C# code?

string str = "Hello World";
Console.WriteLine(str.Substring(0, 5));

This code will output the substring of the string str starting at index 0 and ending at index 4 (5 characters in total). The output will be 'Hello'.

What does the following DRAKON-C# code do?

List numbers = new List {1, 2, 3, 4, 5};
numbers.RemoveAt(2);
Console.WriteLine(string.Join(", ", numbers));

This code declares a list of integers, removes the element at index 2 (which is the number 3), and then prints the remaining elements of the list to the console. The output will be '1, 2, 4, 5'.

What does the following DRAKON-C# code do?

Thread thread = new Thread(() => {
Console.WriteLine("Hello from the thread");
});
thread.Start();

This code creates a new thread and assigns a lambda function to it that prints 'Hello from the thread' to the console. The thread is then started, executing the assigned function.

What does the following DRAKON-C# code do?

public class Person {
public string Name { get; set; }
public int Age { get; set; }
}
Person person = new Person { Name = "John", Age = 30 };
Console.WriteLine(person.Name);

This code defines a class named Person with two properties: Name and Age. It then creates a new instance of the Person class, sets the Name property to 'John' and the Age property to 30, and then prints the Name property of the person object to the console. The output will be 'John'.

What will be the output of the following DRAKON-C# code?

async Task GetNumberAsync() {
await Task.Delay(1000);
return 5;
}
var task = GetNumberAsync();
Console.WriteLine(task.Result);

This code defines an asynchronous method that returns a Task<int>. It delays for 1 second and then returns the number 5. The method is then called and its result is printed to the console. The output will be '5', but it will be printed after a delay of 1 second.

Wrap-up questions

Final candidate for DRAKON-C# role questions

The final few interview questions for a DRAKON-C# candidate should typically focus on a combination of technical skills, personal goals, growth potential, team dynamics, and company culture.

How would you use DRAKON in a large, complex project?

In a large, complex project, DRAKON can be used to design and document the system. It can be particularly useful for representing complex logic and algorithms, and for communicating these to other members of the team.

What are the limitations of DRAKON?

One of the limitations of DRAKON is that it can be more time-consuming to create a DRAKON diagram than to write code. Also, not all programming concepts can be easily represented in DRAKON.

How would you represent a switch-case statement in DRAKON?

In DRAKON, a switch-case statement can be represented using the 'Choice' icon for the switch, and the 'Action' icons for each case.

Describe the difference between the 'Action' and 'Address' icons in DRAKON.

The 'Action' icon in DRAKON is used to represent a step or operation. The 'Address' icon is used to represent a point in the diagram that can be referred to from other parts of the diagram.

How would you represent an if-else statement in DRAKON?

In DRAKON, an if-else statement can be represented using the 'Question' icon for the condition, and the 'Action' icons for the 'if' and 'else' blocks.
