How would you declare a variable in AngelScript?

You declare a variable in AngelScript by specifying the type followed by the variable name. For example, 'int myVariable;' declares an integer variable named 'myVariable'.

What are the basic data types in AngelScript?

The basic data types in AngelScript include int, float, double, bool, and string.

Describe the difference between '==' and '===' in AngelScript.

In AngelScript, '==' is used for equality comparison, while '===' is used for identity comparison. The former checks if the values of two operands are equal or not, and the latter checks if two operands refer to the same object.

Next 20 minutes

Specific AngelScript 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 a class and an interface in AngelScript.

A class is a blueprint for creating objects, it can contain fields, methods, and constructors. An interface, on the other hand, is a contract for classes to follow. It contains declarations of methods, properties, and events, but no implementation.

How would you handle exceptions in AngelScript?

AngelScript does not have built-in exception handling. However, you can use the 'assert' statement to check for conditions and halt execution if the condition is not met.

What are the different types of arrays in AngelScript and how are they different?

AngelScript has two types of arrays: 'array' and 'dictionary'. An 'array' is a collection of elements of the same type, while a 'dictionary' is a collection of key-value pairs.

Describe the difference between public, private, and protected access specifiers in AngelScript.

Public members are accessible from anywhere, private members are only accessible within their own class, and protected members are accessible within their own class and by subclasses.

How would you implement inheritance in AngelScript?

Inheritance in AngelScript is implemented using the 'class' keyword. For example, 'class Child : Parent { //code }' creates a Child class that inherits from the Parent class.

Digging deeper

Code questions

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

What does the following AngelScript code do?
int add(int a, int b) {
  return a + b;
}
This code defines a function named 'add' that takes two integer parameters, adds them together, and returns the result.
What will be the output of the following AngelScript code?
void main() {
  string str = 'Hello, World!';
  Print(str);
}
This code will print 'Hello, World!' to the console.
What does the following AngelScript code do?
array arr = {1, 2, 3, 4, 5};
arr.removeAt(2);
This code creates an array of integers with the values 1, 2, 3, 4, 5. It then removes the third element from the array, which is the number 3.
What does the following AngelScript code do?
shared class SharedClass {
  int value;
}
This code defines a shared class named 'SharedClass' with an integer member variable named 'value'. Shared classes are used in AngelScript for multithreading and can be accessed by multiple threads.

Wrap-up questions

Final candidate for AngelScript 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 AngelScript application deployments.

A function is a standalone unit of code, while a method is a function associated with an object or class.

How would you create a multidimensional array in AngelScript?

A multidimensional array in AngelScript can be created like this: 'int[][] myArray;'. This creates an array of arrays of integers.
