DRAKON-Apex is a programming language that is based on the DRAKON visual language developed by the Russian space program. The main philosophy behind DRAKON-Apex is to improve the readability and understandability of code, making it easier for people to learn and use. The language has a unique visual structure that aims to reduce cognitive load, making it easier to understand complex programs. It also has a strong emphasis on error prevention, with features designed to reduce the likelihood of common programming mistakes. This makes DRAKON-Apex particularly suitable for critical systems where errors can have serious consequences.

First 20 minutes

General DRAKON-Apex app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in DRAKON-Apex 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 flowcharts and algorithms in a way that's easy to understand, reducing the chance of errors.

What are the main advantages of using DRAKON?

DRAKON's main advantages are its simplicity, clarity, and the ability to visualize complex algorithms and systems. It's also language-agnostic, meaning it can be used with any programming language.

Describe the difference between DRAKON and traditional flowcharting methods.

Traditional flowcharting methods often use multiple shapes to represent various operations, while DRAKON uses a single shape. This makes DRAKON diagrams easier to read and understand, especially for complex algorithms.

How would you integrate DRAKON-Apex with other software?

DRAKON-Apex can be integrated with other software through APIs, file imports/exports, or by using it as a standalone tool and manually transferring data.

What are the main features of DRAKON-Apex?

DRAKON-Apex features include its ability to generate code in multiple programming languages, support for creating DRAKON diagrams, and the ability to export diagrams to various formats.

Next 20 minutes

Specific DRAKON-Apex 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 DRAKON-Apex and other DRAKON editors.

DRAKON-Apex is specifically designed for the Apex programming language, while other DRAKON editors may support multiple or different languages. The features and user interface may also vary.

How would you handle a large and complex DRAKON diagram in DRAKON-Apex?

I would break it down into smaller, manageable parts or modules. I would also make use of DRAKON's 'Silhouette' feature, which provides a high-level overview of the diagram.

What are the limitations of DRAKON-Apex?

DRAKON-Apex is specifically designed for the Apex language, so it may not support all features of other languages. Additionally, while it simplifies diagram creation, it might not be suitable for all types of algorithms or systems.

Describe the difference between DRAKON's 'Silhouette' and 'Icon' modes.

'Silhouette' mode provides a high-level overview of the diagram, while 'Icon' mode allows for detailed editing of the diagram. Both modes are useful for different stages of diagram creation and editing.

How would you use DRAKON-Apex to improve code quality?

I would use DRAKON-Apex to create clear and understandable representations of the code's logic. This would help identify potential issues or areas for improvement, and make the code easier to maintain and update.

Digging deeper

Code questions

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

What does this simple DRAKON-Apex code do?
public class HelloWorld {
 public static void main(String[] args) {
 System.out.println('Hello, World!');
 }
}
This code prints 'Hello, World!' to the console.
What does this DRAKON-Apex code snippet do?
public class Test {
 public static void main(String[] args) {
 Integer x = 5;
 x = x + 10;
 System.out.println(x);
 }
}
This code initializes an Integer variable 'x' with a value of 5, adds 10 to it, and then prints the result, which is 15.
What will be the output of this DRAKON-Apex code?
public class ArrayTest {
 public static void main(String[] args) {
 Integer[] arr = {1, 2, 3, 4, 5};
 for(Integer i: arr) {
 System.out.println(i);
 }
 }
}
This code will print the numbers 1 through 5, each on a new line.
What does this DRAKON-Apex code snippet do?
public class ThreadTest extends Thread {
 public void run() {
 System.out.println('Thread is running.');
 }
 public static void main(String args[]) {
 ThreadTest t1 = new ThreadTest();
 t1.start();
 }
}
This code creates a new thread and starts it. The new thread then prints 'Thread is running.' to the console.

Wrap-up questions

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

What are the key considerations when creating a DRAKON diagram for a complex system?

Key considerations include understanding the system's logic and processes, deciding on the level of detail to include in the diagram, and ensuring the diagram is clear and easy to understand.

Describe the difference between DRAKON and UML diagrams.

DRAKON diagrams focus on representing algorithms and flow of control, while UML diagrams can represent various aspects of a system, including its structure, behavior, and interactions. DRAKON diagrams are also generally simpler and easier to understand.

How would you use DRAKON-Apex in a team environment?

I would use DRAKON-Apex to create diagrams that represent our code's logic, which would help the team understand and work with the code. I would also use it to document our systems and processes, aiding in communication and onboarding.
