Hiring guide for TOM-2 Engineers

TOM-2 Developer Hiring Guide

The TOM-2 programming language, developed in the late 1960s by the Dutch company Electrologica, was a pioneer in facilitating structured programming. It was designed for use on Electrologica's X8 computer and served as an early example of a high-level language with block structure. The language allowed for complex data structures and enabled advanced error handling. Despite its innovative features, TOM-2 did not gain widespread use due to the limited availability of the X8 computer. Information about TOM-2 is derived from historical documents preserved by the Computer History Museum and academic research on early programming languages.

First 20 minutes

General TOM-2 app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in TOM-2 application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

How would you describe the basic structure of a TOM-2 program?
A TOM-2 program is structured around classes, methods, and instances. It begins with a class definition, followed by method definitions within the class. Instances of the class can then be created and manipulated.
What are the key features of TOM-2?
TOM-2 has several key features including strong typing, garbage collection, exception handling, and support for object-oriented programming.
Describe the difference between strong typing and weak typing in TOM-2.
In TOM-2, strong typing means that the type of a variable is checked at compile time. Weak typing, on the other hand, allows the type of a variable to be changed at runtime.
How would you handle exceptions in TOM-2?
In TOM-2, exceptions are handled using the try-catch-finally construct. The try block contains the code that might throw an exception, the catch block contains the code to handle the exception, and the finally block contains the code that is always executed, whether an exception is thrown or not.
What are the benefits of garbage collection in TOM-2?
Garbage collection in TOM-2 helps to prevent memory leaks by automatically freeing up memory that is no longer in use. This makes memory management easier for the developer.

Next 20 minutes

Specific TOM-2 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 create a class in TOM-2?
In TOM-2, a class is created using the 'class' keyword, followed by the name of the class and a pair of curly braces. The methods and properties of the class are defined within the curly braces.
Describe the difference between a method and a function in TOM-2.
In TOM-2, a method is a function that is associated with a particular class. A function, on the other hand, is a standalone piece of code that can be called independently.
What are the principles of object-oriented programming in TOM-2?
The principles of object-oriented programming in TOM-2 are encapsulation, inheritance, and polymorphism. Encapsulation is the bundling of data and methods that operate on that data. Inheritance is the ability of a class to inherit properties and methods from another class. Polymorphism is the ability of an object to take on many forms.
How would you implement inheritance in TOM-2?
In TOM-2, inheritance is implemented using the 'extends' keyword. The child class is defined as extending the parent class, which means it inherits all the properties and methods of the parent class.
Describe the difference between public, private, and protected access modifiers in TOM-2.
In TOM-2, public access modifier means that the property or method can be accessed from anywhere. Private means it can only be accessed within the class it is defined. Protected means it can be accessed within the class and by any subclasses.

The ideal back-end app developer

What you’re looking to see on the TOM-2 engineer at this point.

At this point, a skilled TOM-2 engineer should demonstrate strong problem-solving abilities, proficiency in TOM-2 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 TOM-2.

What does this simple TOM-2 code do?
def hello():
	print('Hello, World!')
This code defines a function named 'hello' that prints 'Hello, World!' when called. The function is then called, so 'Hello, World!' is printed to the console.
What does this TOM-2 code do?
x = 5
y = '7'
print(x + int(y))
This code declares an integer variable 'x' with a value of 5, and a string variable 'y' with a value of '7'. It then prints the sum of 'x' and the integer value of 'y', which is 12.
What will be the output of the following TOM-2 code?
def change_list(my_list):
	my_list[1] = 'changed'
my_list = ['one', 'two', 'three']
This code will output ['one', 'changed', 'three']. The function 'change_list' is defined to change the second element of a given list to 'changed'. The function is then called with 'my_list' as an argument, changing its second element.
What does the following TOM-2 code do?
import threading

def print_nums():
	for i in range(5):

thread = threading.Thread(target=print_nums)
This code creates a new thread and runs the 'print_nums' function in it. The 'print_nums' function prints numbers from 0 to 4. The main program continues to run in parallel with the new thread.

Wrap-up questions

Final candidate for TOM-2 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 TOM-2 application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

What are the uses of interfaces in TOM-2?
Interfaces in TOM-2 are used to define a contract for classes. They specify what methods a class must implement, but do not provide any implementation for these methods.
How would you implement polymorphism in TOM-2?
In TOM-2, polymorphism is implemented through method overriding and interfaces. Method overriding allows a subclass to provide a different implementation of a method that is already provided by its parent class. Interfaces allow objects to take on many forms.
Describe the difference between overloading and overriding in TOM-2.
In TOM-2, overloading is the ability to define multiple methods with the same name but different parameters. Overriding is the ability of a subclass to provide a different implementation of a method that is already provided by its parent class.
