Hiring guide for Pizza Programming Language(Pizza) Engineers

Pizza Programming Language(Pizza) Developer Hiring Guide

The Pizza Programming Language, often shortened to Pizza, is a pioneering open-source software programming language developed in the late 1990s. It was created by Martin Odersky, Philip Wadler, and their team at the University of South Australia as an extension of Java with added features like parametric polymorphism and first-class functions. The project served as a precursor to Generic Java (GJ) and eventually influenced the development of Java 5.0's generics feature. Its compiler was written in Standard ML and translated into Java bytecode for execution on any standard JVM (Java Virtual Machine). Despite its historical significance, Pizza is no longer actively maintained or widely used today.

First 20 minutes

General Pizza Programming Language(Pizza) app knowledge and experience

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

What are the main features of the Pizza programming language?
Pizza programming language has features like parametric polymorphism, higher-order functions, class types and virtual types.
How would you define a class in Pizza?
In Pizza, a class is defined using the 'class' keyword followed by the class name, and the class body enclosed in curly braces. For example, 'class MyClass { }'.
What is the use of the 'extends' keyword in Pizza?
The 'extends' keyword in Pizza is used for class inheritance. It allows a class to inherit the properties and methods of another class.
How would you implement polymorphism in Pizza?
Polymorphism in Pizza can be implemented using interfaces and inheritance. An interface can be implemented by any class and a class can extend another class, allowing for polymorphic behavior.
What are the data types supported by Pizza?
Pizza supports various data types including int, char, boolean, and float. It also supports reference types like arrays, classes, and interfaces.

Next 20 minutes

Specific Pizza Programming Language(Pizza) 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.

How would you declare and initialize an array in Pizza?
In Pizza, an array can be declared and initialized using the 'new' keyword. For example, 'int[] myArray = new int[5];' declares and initializes an array of integers.
Describe the difference between a class and an interface in Pizza.
In Pizza, a class is a blueprint for creating objects and can contain fields and methods, while an interface is a reference type that can contain abstract methods and constants. A class implements an interface, and an object is an instance of a class.
How would you handle exceptions in Pizza?
Exceptions in Pizza can be handled using try-catch blocks. The 'try' block contains the code that might throw an exception, and the 'catch' block contains the code to handle the exception.
What is the purpose of the 'final' keyword in Pizza?
The 'final' keyword in Pizza is used to indicate that a variable's value cannot be changed, a method cannot be overridden, or a class cannot be subclassed.
How would you create a generic class in Pizza?
A generic class in Pizza can be created by using a type parameter in angle brackets after the class name. For example, 'class MyClass { }' creates a generic class.

The ideal back-end app developer

What you’re looking to see on the Pizza Programming Language(Pizza) engineer at this point.

At this point, a skilled Pizza Programming Language(Pizza) engineer should demonstrate strong problem-solving abilities, proficiency in Pizza Programming Language(Pizza) 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 Pizza Programming Language(Pizza).

What does the following simple Pizza code do?
class HelloWorld {
 public static void main(String[] args) {
 System.out.println("Hello, World!");
This code prints 'Hello, World!' to the standard output.
What will be the output of the following Pizza code?
class Test {
 public static void main(String[] args) {
 int a = 10;
 int b = 20;
 System.out.println(a + b);
This code will output '30' to the standard output. It adds two integers a and b, and then prints the result.
What does the following Pizza code do?
class Test {
 public static void main(String[] args) {
 int[] arr = {1, 2, 3, 4, 5};
 for (int i : arr) {
This code prints all elements of the array 'arr' to the standard output. It uses a for-each loop to iterate through the array.
What does the following Pizza code do?
class Test {
 public static void main(String[] args) {
 Thread t = new Thread(() -> {
 System.out.println("New thread");
This code creates a new thread and prints 'New thread' to the standard output in the new thread. It uses a lambda expression to define the run method of the thread.

Wrap-up questions

Final candidate for Pizza Programming Language(Pizza) 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 Pizza Programming Language(Pizza) application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

Describe the difference between 'public', 'private', and 'protected' access modifiers in Pizza.
In Pizza, 'public' access modifier allows a member to be accessed from any other class, 'private' allows it to be accessed only within its own class, and 'protected' allows it to be accessed within its own class and by subclasses and classes in the same package.
How would you implement multithreading in Pizza?
Multithreading in Pizza can be implemented by creating a class that extends the 'Thread' class or implements the 'Runnable' interface. The 'run()' method contains the code to be executed in the new thread.
What is the use of the 'synchronized' keyword in Pizza?
The 'synchronized' keyword in Pizza is used to control the access of multiple threads to a shared resource. It ensures that only one thread can access the resource at a time.
