A++ is a minimalistic programming language that was developed to serve as a learning instrument rather than a full-fledged programming tool. It is an abstraction of Assembly language, designed to be easy and simple for students to understand the basic concepts of programming at the machine level. A++ consists only of 33 commands, each represented by an uppercase letter or symbol. Despite its simplicity, it can be used to create complex programs and algorithms due its Turing completeness. However, it lacks many features found in more modern languages such as object-oriented design or high-level syntax structures.

First 20 minutes

General A++ app knowledge and experience

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

How would you declare a variable in A++?

In A++, you declare a variable using the 'let' keyword, followed by the variable name, equals sign, and the value. For example, 'let x = 10;'.

What are the data types supported in A++?

A++ supports several data types including integer, float, boolean, string, array, and object.

Describe the difference between 'let' and 'const' in A++.

'let' is used to declare a variable that can be reassigned, while 'const' is used to declare a variable whose value is constant and cannot be changed.

How would you create a function in A++?

In A++, you create a function using the 'function' keyword, followed by the function name, parentheses, and curly braces. For example, 'function myFunction() {}'.

What are the control structures available in A++?

A++ supports several control structures including 'if', 'else', 'for', 'while', and 'switch'.

Next 20 minutes

Specific A++ 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 '==' and '===' in A++.

'==' checks for equality of values, while '===' checks for equality of both value and type.

How would you handle exceptions in A++?

In A++, you handle exceptions using the 'try', 'catch', and 'finally' blocks. The 'try' block contains the code that may throw an exception, the 'catch' block handles the exception, and the 'finally' block contains code that is always executed.

What are the different ways to create an object in A++?

In A++, you can create an object using the object literal syntax, the 'new' keyword, or the 'Object.create()' method.

Describe the difference between 'null' and 'undefined' in A++.

'null' is an assignment value that means no value or no object. It is an intentional absence of any object value. 'undefined' means a variable has been declared but has not yet been assigned a value.

How would you implement inheritance in A++?

In A++, you can implement inheritance using the 'extends' keyword. The child class extends the parent class, inheriting its properties and methods.

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 A++.

What does the following code do?
{
	"name": "John",
	"age": 30,
	"city": "New York"
}
This code defines a JSON object with three properties: name, age, and city. The values for these properties are 'John', 30, and 'New York' respectively.
What will be the output of the following code?
{
	"employees":[
		{"firstName":"John", "lastName":"Doe"},
		{"firstName":"Anna", "lastName":"Smith"},
		{"firstName":"Peter", "lastName":"Jones"}
	]
}
The output is a JSON object that contains an array of employees. Each employee is represented as a separate JSON object with properties firstName and lastName.
What does the following JSON code do?
{
	"books": [
		{"title": "Harry Potter", "author": "J.K. Rowling"},
		{"title": "Lord of the Rings", "author": "J.R.R. Tolkien"}
	]
}
This JSON code represents a collection of books. Each book is a separate object with properties title and author. The collection is represented as an array.
What will be the output of the following code?
{
	"thread": {
		"id": 1,
		"name": "Thread-1",
		"priority": 5
	}
}
The output is a JSON object that represents a thread. The thread object has properties id, name, and priority, with respective values of 1, 'Thread-1', and 5.

Wrap-up questions

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

What are the different types of errors in A++?

A++ has three types of errors: Syntax errors, Runtime errors, and Logic errors.

Describe the difference between a method and a function in A++.

A method is a function that is a property of an object. A function is a block of code designed to perform a particular task.

How would you prevent code blocks from interfering with each other in A++?

In A++, you can prevent code blocks from interfering with each other by using closures, which allow you to encapsulate code.
