WinDev is a powerful integrated development environment (IDE) initially released in 1993 by the French company, PC SOFT. It allows developers to create applications, primarily for Windows, but also for other platforms like Linux and Web services. The software utilizes its proprietary WLanguage, which is an object-oriented programming language with syntax similar to that of English. According to PC SOFT, WinDev's strengths lie in its rapid application development and full-stack capabilities. Its unique features have made it a popular choice among European developers for creating commercial applications.

First 20 minutes

General WinDev app knowledge and experience

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

How would you describe the main features of WinDev?

WinDev is a powerful integrated development environment that allows developers to create applications for Windows, Linux, .NET, Java, and other platforms. It supports multiple programming languages, has a visual editor for designing user interfaces, and includes tools for database management, web services, and mobile development.

What are the advantages of using WinDev over other development environments?

WinDev offers a highly productive environment with a wide range of features and tools. It supports multiple programming languages, allows for rapid application development, and includes a powerful database management system. It also provides a unified development experience across different platforms.

Describe the difference between WinDev, WebDev, and WinDev Mobile.

WinDev is used for developing Windows applications, WebDev is used for creating web applications, and WinDev Mobile is used for developing mobile applications. All three are part of the same suite and share a common language and development environment.

How would you use WinDev to create a database application?

WinDev includes a powerful database management system that allows developers to create, manage, and manipulate databases. You can use the visual editor to design the database structure, use the integrated SQL editor to write queries, and use the data control tools to bind data to user interface elements.

What are the steps to debug a WinDev application?

WinDev includes a built-in debugger that allows developers to step through their code, set breakpoints, and inspect variables. To debug an application, you would first set breakpoints at the relevant points in your code, then run the application in debug mode, and finally step through the code, inspecting variables and evaluating expressions as needed.

Next 20 minutes

Specific WinDev 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 procedural and object-oriented programming in WinDev.

Procedural programming in WinDev involves writing procedures or functions that perform specific tasks, while object-oriented programming involves defining classes that encapsulate data and methods. Object-oriented programming allows for more modular and reusable code.

How would you handle errors in a WinDev application?

WinDev provides several mechanisms for error handling, including exception handling and error checking functions. You can use the TRY..CATCH..END structure to catch and handle exceptions, and use functions like ErrorOccurred() to check for errors.

What are the best practices for optimizing performance in a WinDev application?

Performance optimization in WinDev involves techniques like efficient database design and query optimization, efficient use of memory and resources, and proper error handling. It also involves using the profiling and performance analysis tools provided by WinDev to identify and address performance bottlenecks.

How would you implement security in a WinDev application?

Security in a WinDev application can be implemented at several levels, including user authentication, data encryption, secure communication, and proper error handling. WinDev provides tools and functions for implementing all these aspects of security.

Describe the difference between synchronous and asynchronous programming in WinDev.

Synchronous programming in WinDev involves writing code that executes sequentially, with each operation blocking until it completes. Asynchronous programming involves writing code that can execute in parallel, with operations that can start and complete in any order.

Oops! Something went wrong while submitting the form.

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

What does the following WinDev code do?
Info('Hello, World!')
This code displays a message box with the text 'Hello, World!'
What will be the output of the following WinDev code?
MyString is string = 'WinDev'
Info(Left(MyString, 3))
This code will display a message box with the text 'Win'. The 'Left' function returns the first three characters of the string 'WinDev'.
What does the following WinDev code do?
MyArray is array of 5 int = [1, 2, 3, 4, 5]
Sort(MyArray, Sort Ascending)
Info(MyArray)
This code sorts the array 'MyArray' in ascending order and then displays the sorted array in a message box.
What will be the output of the following WinDev code?
MyThread is Thread
MyThread.Start(ProcThread)
PROCEDURE ProcThread()
Info('Thread started')
END
This code starts a new thread and displays a message box with the text 'Thread started' in the new thread.

Wrap-up questions

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

How would you use WinDev to create a multi-threaded application?

WinDev provides support for multi-threading through the ThreadExecute and ThreadWait functions. You can use these functions to create and manage threads, allowing for parallel execution of code.

What are the steps to deploy a WinDev application?

Deploying a WinDev application involves compiling the application into an executable file, packaging the application with any necessary resources and dependencies, and distributing the application to the end users. WinDev provides tools for all these steps.

How would you handle data persistence in a WinDev application?

Data persistence in a WinDev application can be handled through the use of databases, files, or other storage mechanisms. WinDev provides a powerful database management system, as well as functions for reading and writing files.
