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# app knowledge and experience

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

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.

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 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 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.

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.

Next 20 minutes

Specific DRAKON-C# 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 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.

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.

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.

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.

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.

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

Wrap-up questions

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

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.

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 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.
