Hiring guide for Charisma Engineers

Charisma Developer Hiring Guide

Charisma is a computer programming language developed in the 1970s by Honeywell Information Systems. It was designed as an application development system for their Series 60 (Level 62) mainframe computers. According to "The Encyclopedia of Computer Languages", Charisma was primarily used for business data processing and report generation tasks. This high-level language allowed developers to create applications with less coding effort compared to assembly languages, thereby enhancing productivity. Despite its initial popularity, Charisma has largely been replaced by more modern programming languages today.

Digging deeper

Code questions

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

What does this simple JSON object represent?
{ 'name': 'John Doe', 'age': 30, 'city': 'New York' }
This code represents a JSON object with three properties: name, age, and city. The values for these properties are 'John Doe', 30, and 'New York' respectively.
What does this JSON syntax do?
{ 'employees': [ { 'firstName':'John', 'lastName':'Doe' }, { 'firstName':'Anna', 'lastName':'Smith' }, { 'firstName':'Peter', 'lastName':'Jones' } ] }
This JSON syntax defines an object 'employees' which is an array of objects. Each object in the array represents an employee and has two properties: firstName and lastName.
What will be the output of this JSON array manipulation?
{ 'fruits': [ 'apple', 'banana', 'cherry' ] }.fruits.push('dragonfruit')
This code will add the string 'dragonfruit' to the end of the 'fruits' array in the JSON object. The new array will be ['apple', 'banana', 'cherry', 'dragonfruit'].
What does this JSON code do in terms of threading or concurrency?
{ 'thread': { 'id': 1, 'status': 'running', 'priority': 'high' } }
This JSON object represents a thread with properties id, status, and priority. However, JSON itself doesn't have any built-in support for threading or concurrency. The actual handling of threading or concurrency would be done by the programming language using this JSON object.

Wrap-up questions

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

What are some of the limitations of Charisma?
While Charisma is a powerful platform, it does have limitations. For example, it may not be suitable for applications requiring complex customizations or unique functionalities that are not supported by Charisma.
How would you train a new team member on Charisma?
I would start with the basics and gradually move to more complex topics. I would also provide them with resources for self-learning and be available to answer any questions they may have.
Describe an instance where you had to use a unique feature of Charisma to solve a problem.
In a project, we had to integrate with an external system. We utilized Charisma's powerful API to achieve this, which saved us a lot of time and effort.
