Hiring guide for Winbatch Engineers

Winbatch Developer Hiring Guide

WinBatch is a robust scripting language developed by Wilson WindowWare, originally launched in 1991. It's designed for automating Windows desktop and server operating systems, proving essential for system administrators and power users. The language's versatility extends to tasks such as network automation, FTP uploads, and user interface manipulation. Its unique feature includes a compiler that transforms scripts into executable files (.EXE), enhancing security and portability. Sources of information include the official WinBatch website and various software development forums.

First 20 minutes

General Winbatch app knowledge and experience

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

How would you define Winbatch?
Winbatch is a scripting language for Windows, developed by Wilson WindowWare. It is used for automating tasks in Windows and is designed to be easy to use for both programmers and non-programmers.
What are the main features of Winbatch?
Winbatch provides a rich set of commands for file and directory manipulation, user interface automation, data manipulation, and more. It also supports COM and OLE automation, and can interact with most Windows applications.
Describe the difference between Winbatch and PowerShell.
While both are scripting languages for Windows, they have different focuses. Winbatch is designed to be easy to use and learn, and is great for automating tasks in Windows. PowerShell, on the other hand, is more powerful and flexible, but also more complex. It is designed for system administration and automation tasks.
How would you use Winbatch to automate a repetitive task?
You would write a script in Winbatch that performs the task, and then schedule it to run at regular intervals using the Windows Task Scheduler. The script would use Winbatch commands to interact with the user interface of the application, manipulate files and directories, and perform other tasks as needed.
What are some common uses of Winbatch?
Winbatch is commonly used for automating repetitive tasks, such as file and directory manipulation, user interface automation, data manipulation, and more. It can also be used for system administration tasks, such as managing user accounts, installing software, and configuring system settings.

Next 20 minutes

Specific Winbatch 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 compiled and an interpreted Winbatch script.
A compiled Winbatch script is converted into machine code before it is run, which makes it faster and more efficient. An interpreted script, on the other hand, is read and executed line by line by the Winbatch interpreter, which makes it slower but easier to debug and modify.
How would you debug a Winbatch script?
You would use the Winbatch debugger, which allows you to step through the script line by line, inspect the values of variables, and set breakpoints. You can also use the 'Debug' command in the script to print out the values of variables at certain points.
What are some best practices for writing Winbatch scripts?
Some best practices include using meaningful variable names, commenting your code, handling errors properly, and keeping your scripts simple and modular. It's also a good idea to test your scripts thoroughly before deploying them.
Describe the difference between synchronous and asynchronous execution in Winbatch.
Synchronous execution means that the script waits for each command to complete before moving on to the next one. Asynchronous execution, on the other hand, means that the script can continue executing other commands while waiting for a command to complete.
How would you handle errors in a Winbatch script?
You would use the 'OnError' command to specify what the script should do when an error occurs. This could be to display an error message, write to a log file, or perform some other action. You can also use the 'ErrorMode' command to control whether the script should stop or continue when an error occurs.

The ideal back-end app developer

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

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

What does the following Winbatch code do?
IntControl(12, 0, 0, 0, 0)
This code disables the 'Ctrl+Break' key combination in a Winbatch script.
What will be the output of the following Winbatch code?
message('Hello', 'World')
This code will display a message box with the title 'Hello' and the message 'World'.
What does the following Winbatch code do?
ArraySort(array, 'D', 'A')
This code sorts the 'array' in ascending order ('A') based on the data type of the array elements ('D' for double).
What does the following Winbatch code do?
ThreadCreate('ThreadFunction', 'Hello, World')
This code creates a new thread that executes the function 'ThreadFunction' with the argument 'Hello, World'.

Wrap-up questions

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

What are some limitations of Winbatch?
Winbatch is not as powerful or flexible as some other scripting languages, such as PowerShell or Python. It also doesn't support multi-threading or multi-processing, and it can be slower than compiled languages like C++ or Java.
Describe the difference between a function and a subroutine in Winbatch.
A function is a block of code that performs a specific task and returns a value, while a subroutine is a block of code that performs a task but does not return a value. Functions are used when you need to perform a task and get a result, while subroutines are used for tasks that don't need to return a result.
How would you use Winbatch to interact with a database?
You would use the 'Sql' commands in Winbatch to connect to the database, execute SQL queries, and retrieve results. You can also use the 'ODBC' commands to interact with databases that support the ODBC standard.
