Hiring guide for Dyalect++ Engineers

Dyalect++ Developer Hiring Guide

Dyalect++ is a dynamic programming language, designed to offer simplicity and flexibility for software development. It was developed by the Dyalect team as an open-source project, aiming to provide a lightweight yet powerful tool for developers. The language features a robust type system and supports both object-oriented and functional programming paradigms. Its syntax is influenced by C++, hence the name Dyalect++. The source code of this innovative language can be found on GitHub, reflecting its commitment to community-driven development.

First 20 minutes

General Dyalect++ app knowledge and experience

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

How would you define Dyalect++?
Dyalect++ is a dynamic programming language that is designed for systems programming and scripting. It is a statically typed, compiled language with a focus on simplicity and efficiency.
What are the key features of Dyalect++?
Some of the key features of Dyalect++ include its simplicity, efficiency, static typing, and its suitability for systems programming and scripting.
Describe the difference between static typing and dynamic typing in Dyalect++.
In Dyalect++, static typing means that the type of a variable is known at compile time, which can help catch errors early. Dynamic typing, on the other hand, means that the type is checked at runtime, which can offer more flexibility.
How would you handle exceptions in Dyalect++?
In Dyalect++, exceptions can be 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 code that is always executed, whether an exception is thrown or not.
What are the data types available in Dyalect++?
Dyalect++ supports several data types, including integers, floating-point numbers, booleans, strings, arrays, and user-defined types.

Next 20 minutes

Specific Dyalect++ 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 implement polymorphism in Dyalect++?
In Dyalect++, polymorphism can be implemented using interfaces. An interface defines a contract for what a class can do, without specifying how it does it. A class can implement multiple interfaces, allowing for polymorphism.
Describe the difference between a class and an object in Dyalect++.
In Dyalect++, a class is a blueprint for creating objects. It defines the properties and methods that an object will have. An object, on the other hand, is an instance of a class. It has state (properties) and behavior (methods).
What are the principles of Object-Oriented Programming (OOP) in Dyalect++?
The principles of OOP in Dyalect++ are encapsulation, inheritance, and polymorphism. Encapsulation is the bundling of data and methods that operate on that data. Inheritance is the ability for a class to inherit properties and methods from another class. Polymorphism is the ability for a class to have multiple forms.
How would you implement inheritance in Dyalect++?
In Dyalect++, inheritance can be implemented using the extends keyword. A class that extends another class inherits all its properties and methods.
Describe the difference between public, private, and protected access modifiers in Dyalect++.
In Dyalect++, 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 subclasses.

The ideal back-end app developer

What you’re looking to see on the Dyalect++ engineer at this point.

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

What does the following Dyalect++ code do?
var x = 5; 
var y = 10; 
var z = x + y;
This code declares two variables 'x' and 'y', assigns them the values 5 and 10 respectively, and then adds these values together and assigns the result to a third variable 'z'.
What will be the output of the following Dyalect++ code?
var x = 'Hello'; 
var y = 'World'; 
print(x + ' ' + y);
The output of this code will be 'Hello World'. It concatenates the strings 'Hello', ' ' (a space), and 'World' and then prints the result.
What does the following Dyalect++ code do?
var arr = [1, 2, 3, 4, 5]; 
This code declares an array 'arr' with five elements, adds a sixth element to the end of the array using the 'push' function, and then prints the array.
What will be the output of the following Dyalect++ code?
var x = 5; 
var y = 10; 
thread { 
  x = x + 1; 
print(x + y);
The output of this code will be 16. It starts a new thread that increments the value of 'x' by 1, and then it adds 'x' and 'y' together and prints the result.

Wrap-up questions

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

What are the control structures available in Dyalect++?
Dyalect++ supports several control structures, including if-else, switch-case, for, while, and do-while loops.
How would you create a custom data type in Dyalect++?
In Dyalect++, a custom data type can be created using the class keyword. The class can have properties and methods, and can also implement interfaces and extend other classes.
Describe the difference between pass-by-value and pass-by-reference in Dyalect++.
In Dyalect++, pass-by-value means that a copy of the variable is passed to the function, so changes made inside the function do not affect the original variable. Pass-by-reference means that a reference to the variable is passed, so changes made inside the function do affect the original variable.
