Hiring guide for Charisma (programming language) Engineers

Charisma (programming language) Developer Hiring Guide

Charisma is a proprietary programming language developed by Micro Focus for use in its COBOL-based software products. It was first introduced in the late 1980s as an advanced tool to create character-based applications. The language allows programmers to design and manage screen displays, database interactions, and user inputs within COBOL systems. Despite being less popular than mainstream languages like Java or Python, Charisma continues to be used in legacy systems across various industries due to its robustness and compatibility with older technologies. Information about Charisma can be found on the official website of Micro Focus as well as various online tech forums.

The ideal back-end app developer

What you’re looking to see on the Charisma (programming language) engineer at this point.

At this point, a skilled Charisma (programming language) engineer should demonstrate strong problem-solving abilities, proficiency in Charisma (programming language) 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 Charisma (programming language).

What does the following basic Charisma code do?
print('Hello, World!')
This code prints 'Hello, World!' to the standard output.
What does the following Charisma syntax do?
x = 5
y = 10
print(x + y)
This code declares two variables, x and y, assigns them the values 5 and 10 respectively, and then prints the sum of x and y, which is 15.
What does the following Charisma code snippet do?
numbers = [1, 2, 3, 4, 5]
for i in numbers:
  print(i)
This code declares an array named 'numbers' with five elements. It then iterates over each element in the 'numbers' array and prints each number to the standard output.
What does the following Charisma code snippet related to threading do?
import threading
def print_numbers():
  for i in range(10):
    print(i)
thread = threading.Thread(target=print_numbers)
thread.start()
This code defines a function 'print_numbers' that prints numbers from 0 to 9. It then creates a new thread that executes this function and starts the thread. The numbers are printed concurrently to the main program execution.

Wrap-up questions

Final candidate for Charisma (programming language) 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 Charisma (programming language) application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

Describe the difference between a synchronous and an asynchronous operation in Charisma.
In a synchronous operation, the system waits for the operation to complete before moving on to the next operation. In an asynchronous operation, the system does not wait for the operation to complete and can perform other operations in the meantime.
What are the ways to improve the performance of a Charisma application?
Ways to improve the performance of a Charisma application include optimizing queries, using efficient data structures, and minimizing network latency.
How would you handle large data sets in Charisma?
Charisma is designed to handle large data sets efficiently. This includes the use of efficient data structures, optimized queries, and appropriate indexing.
