Hiring guide for DRAKON-Python Engineers

DRAKON-Python Developer Hiring Guide

DRAKON-Python is a programming language that combines the visual flowchart-based DRAKON language with Python, one of the most popular and versatile high-level coding languages. The DRAKON aspect allows for easy visualization of program logic using graphical elements, making it more accessible to those who may not have extensive coding experience. Meanwhile, Python provides a powerful and flexible backbone for executing complex tasks efficiently. This combination makes DRAKON-Python an excellent tool for both teaching programming concepts and developing robust applications in various fields such as data analysis, web development or artificial intelligence among others.

First 20 minutes

General DRAKON-Python app knowledge and experience

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

How would you define DRAKON in simple terms?
DRAKON is a visual language for specifications that is designed to represent complex logic in a way that is easy to understand. It's used to describe how software, business processes, and systems work.
Can you explain the basic syntax of DRAKON-Python?
DRAKON-Python follows the syntax of Python but in a visual form. It has icons for actions, conditions, loops, and other control structures, and these icons are connected by lines to show the flow of control.
How would you create a DRAKON diagram for a simple Python program?
First, identify the control structures in the program, such as loops and conditions. Then, use the appropriate DRAKON icons for these structures and connect them with lines to show the flow of control. Finally, add action icons for the operations in the program.
What are the benefits of using DRAKON-Python?
DRAKON-Python makes complex logic easier to understand, which can help in designing, debugging, and documenting software. It also helps in communicating complex ideas to non-programmers.
How would you convert a DRAKON diagram into Python code?
You can use the DRAKON Editor to convert a DRAKON diagram into Python code. The editor can generate the code automatically based on the diagram.

Next 20 minutes

Specific DRAKON-Python 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.

What are the key elements of a DRAKON diagram?
The key elements of a DRAKON diagram are icons and lines. Icons represent actions, conditions, loops, and other control structures. Lines represent the flow of control.
Describe the difference between DRAKON and traditional flowcharts.
DRAKON is designed to be easier to understand than traditional flowcharts. It has a more consistent layout, uses less symbols, and avoids crossing lines. Also, each DRAKON diagram has a single entry point and a single exit point.
How would you handle errors in DRAKON-Python?
You can use the 'Handle' icon in DRAKON to catch and handle exceptions. The 'Handle' icon is connected to the action that can cause an exception, and to the action that handles the exception.
What are the limitations of DRAKON-Python?
DRAKON-Python is not suitable for all kinds of programs. It's best for programs with complex logic, but not for programs with a lot of simple, sequential operations. Also, DRAKON diagrams can become large and unwieldy for very complex programs.
How would you use DRAKON-Python for team collaboration?
You can use DRAKON-Python to communicate complex ideas to your team members, even if they are not programmers. You can also use it to document your software, which can help in maintaining and enhancing the software.

The ideal back-end app developer

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

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

What does the following DRAKON-Python code do?
def greet(name):
	return 'Hello, ' + name
The code defines a function named 'greet' that takes a single argument 'name'. It returns a string that says 'Hello,' followed by the value of the 'name' argument.
What will be the output of the following DRAKON-Python code?
def add_numbers(a, b):
	return a + b

print(add_numbers(5, 10))
The code defines a function named 'add_numbers' that takes two arguments a and b. It returns the sum of a and b. When the function is called with the arguments 5 and 10, it returns 15. So, the output of the code will be 15.
What does this DRAKON-Python code do?
def reverse_list(lst):
	return lst[::-1]

print(reverse_list([1, 2, 3, 4, 5]))
The code defines a function named 'reverse_list' that takes a list as an argument and returns a new list that is the reverse of the input list. When the function is called with the list [1, 2, 3, 4, 5], it returns [5, 4, 3, 2, 1].
What will be the output of this DRAKON-Python code?
import threading

def print_numbers():
	for i in range(10):

thread = threading.Thread(target=print_numbers)
The code creates a new thread and starts it. The new thread runs the 'print_numbers' function, which prints the numbers from 0 to 9. Therefore, the output of the code will be the numbers from 0 to 9, each on a new line.

Wrap-up questions

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

Describe the difference between DRAKON-Python and regular Python.
DRAKON-Python is a visual representation of Python code. It follows the same logic as Python, but presents it in a way that is easier to understand. Regular Python is textual, while DRAKON-Python is visual.
How would you debug a DRAKON-Python program?
First, check the DRAKON diagram for logical errors. Then, generate the Python code from the diagram and debug the code using a Python debugger.
What are the best practices for creating DRAKON diagrams?
The best practices for creating DRAKON diagrams include: keeping the diagrams simple and easy to understand, avoiding crossing lines, using the appropriate icons for different control structures, and documenting the diagrams well.
