Introduction

One of the most well-known jobs today is a data analyst. By executing the macro, VBA is an excellent tool for automating routine, weekly, or monthly tasks. VBA is a powerful tool for automating repetitive tasks, making it essential for roles in business data analysis or as a VBA developer. To succeed in these positions, you'll need to prepare for a face-to-face interview.

If you are preparing for a vba interview in the future and are looking for a quick guide before your interview, then you have come to the right place.

In this article, we will discuss the top VBA Interview Questions which consist of all types of vba Interview questions.

Basic VBA Interview Questions and Answers 

1. How can VBA be used to format expressions?

The format functions are primarily used to format several expressions, including those involving currency, time, dates, percentages, and numbers. This makes using these functions in VBA much easier. Most apps also support user-defined date, numeric, and text formats.

2. What are the security weaknesses VBA has?

One of the many issues with the Microsoft Visual Basic Application (VBA) is macros. There are macros that can cause trouble for a programmer with the best of intentions. The user, not the programmer as such, is responsible for the security issue as well. 

3. How do we use VBA's data validation function?

One of the most vital VBA concepts is data validation. To fix input errors, the application method and a unique dialogue box are employed. In that situation, we can provide the dialogue box's frame an application procedure. such that the first field with errors can be highlighted with an error message or custom dialogue box.

4. Explain macros. What benefit does using Macros provide?

A set of instructions (or code) put in the Visual Basic module of a VBA Editor is known as a VBA macro. A module contains the code for the VBA macros. Go to the VBA editor and select Insert -> Module to add a module.

Users of Excel can automate routine, repetitive chores on a daily or weekly basis by running a VBA macro. Consequently, employing macros can help you save time, increase productivity, and meet client deadlines.

5. What do you mean when you say "option explicit"?

In VBA, the Option Explicit is used to require that variables be declared before they are utilized. It aids VBA programmers in avoiding type mistakes and producing bug-free code.

6. How can I stop macro recording?

The steps to stop recording macros in your open Excel workbook are listed below:

Step 1: Open your Excel workbook in this step. In the Excel window's main ribbon menu, select the "Developer tab."

Step 2: To stop recording your active macro, click the "Stop Recording" button.

7. What does Excel's fundamental object model mean?

The fundamental Excel object model is shown below.

To access the range or chart, 

select Application -> Workbooks -> Worksheets.

8. How can I access the VBA editor screen quickly?

Using the keyboard shortcut Alt + F11 will bring up the Visual Basic editor window quickly and easily.

9. What kinds of core Modules are available in the Visual Basic Editor?

In VBE, three separate modules are available:

Class Module: Default modules that are frequently used when writing functions.

UserForms: They aid in the creation of GUI applications.

The user can construct new objects, methods, methods, and events with the aid of class modules.

10. How many scope variables exist in VBA?

There are various scope variable levels in the VBA editor. Although we can categorize the variable into the following three levels:

Local Level: In a procedure or function, a DIM statement is used to declare the Local Level variables.

Module Level: The DIM keywords are used to define module-level scope variables on top of VBA code. These variables are unique in that they can be accessible across the entire module.

Global Level: At the beginning of your VBA programming module, use the Public keyword to define the Global Level variables. They are accessible from any location throughout the entire VBA project.

11. Define Array?  How do you define or build an array in VBA?

A group of variables with data of the same data type is called an array. They use the array name and the index number to refer to a specific array value.

The following steps can be used to generate and specify an array variable's size.

Syntax: Dim NameOfArray (IndexNumber) 

Example: Dim arrVal(5) 

12. How do I get rid of the macros in the workbook?

Please refer to the instructions below to remove macros from the workbook.

Step 1: Open your Excel workbook in this step. In the Excel window's main ribbon menu, select the "Developer tab."

Step 2: Next, select the Macros option to examine all the macros that are currently installed in your Excel worksheet.

Step 3: The Macro dialogue box will appear on the screen.

Step 4: Click the 'Delete' command button after selecting the macro name that you want to remove.

Step 5: The confirmation dialogue box will show up in this step.

To confirm the deletion of the chosen macro, click on Ok.

13. What are the various methods for accelerating the VBA macro?

 By using the suggested methods, we can accelerate the execution of VBA macros.

Make sure to not use the 'Variant' Data Type when declaring your variables. thus it requires more room.

Never forget to disable "Screen Updating"

Disable the calculating tools automatically.

Never forget to turn off the Events

Use With Declaration

vbNullString should be used in place of ".

At the conclusion of the process, all memory objects should be released.

14. What are the different Class modules available in VBA?

The different built-in classes are as follows:

Workbook modules

Worksheet modules

15. Describe ADO, ODBC, and OLEDB.

ADO: ActiveX Data Objects, sometimes known as ADO, is a general data access framework that includes DAO capability.

ODBC: A database client application can connect to an external database via ODBC, also known as Open Database Connectivity.

OLEDB: It is a low-level programming interface made to access a variety of data access objects (OLE)

Advanced VBA Interview Questions and Answers

16. What do VBA function pointers do?

Although the applications of VBA (Visual Basic Information) are broad, a function pointer in VBA has some limitations. Because the Windows API can use a function but lacks the functional capabilities to call it back, it provides insufficient support for function pointers. It already has call support, but not callback support.

17. What is the comments style used in VBA?

In order for future programmers to work effortlessly on the same code, comments are used to document the program logic and user information. When representing comments in VBA, there are primarily two approaches.

Every sentence that starts with a single quote is considered a comment.

Alternatively, you can substitute the statement REM for the single quotation mark (').

18. How does VBA's "reference counting" work?

When a variable in VBA exits its scope, the reference object's reference counter is decremented. The reference counter is increased whenever you assign an object reference to another variable. While the event is ended when your reference count reaches zero.

19. Describe the distinction between VBA's subroutines and functions.

The distinction between functions and subroutines is that

Functions do return values, but subroutines never do.

Unlike functions, which were unable to alter the values of the real arguments, subroutines could.

20. explain the VBA code debugging process.

The procedures below can be used to troubleshoot VBA code.

Using Breakpoints (F9)

Execution in steps (F8)

Print the window, then immediately watch it.

21. How can I receive a user's reaction?

Using the input box, which enables users to enter responses in the input bar and press Okay to submit them, you can request a response from the user.

22. What does a VBA loop do?

loop is a section of code that repeatedly repeats. A loop in VBA is a means to define a line of code that will repeat itself. In VBA, there are several ways to construct a loop.

For Each Next

For Next

Do While Loop

Do Until Loop

23. How can conditions be tested in VBA?

There are two main ways to test conditions in VBA: using an IF statement and selecting a case. The two approaches diverge slightly from one another. The chosen case allows you to test several conditions, whereas the IF statement only allows you to test one condition at a time (until you use a nested IF).

24. What purpose does the VBA GoTo Statement serve?

The go-to command in VBA lets you jump between pieces of code. To utilize this statement, you must first establish a label somewhere in the code, and then you must instruct VBA to jump to that label using the go-to statement.

25. Explain the differences between Thisworkbook and Activeworkbook.

While ActiveWorkbook refers to a workbook that is in an active state with an active window, ThisWorkbook refers to a workbook where code is being written. However, ActiveWorkbook and ThisWorkbook are identical when there is only one open worksheet.

26. Describe the process you use to call a number using VBA.

You should adhere to the next steps in order to call a number using VBA.

The Windows OS dialer gift will be started by a shell command in VBA.

The number will be used to connect to your electrical equipment.

You can dial your user by using send keys and shell commands.

While Shell launches the Windows application, Send key commands to Windows to dial in accordance with the application's keystrokes.

The cardboard file application that activates the car dialer feature will often be started by a macro.

27. What makes Current Region characteristics and Used Range different from one another?

Current Region: Any number of blank columns and rows might make this region infinitely variable.

Applied Range: This attribute is used to determine the range of frequently used cells on a worksheet. It gives back an object called "a variety spread" that corresponds to the used range on the specific worksheet.

28. Mention the strategy that was used from the Object Context object to inform MTS whether the deal was successful or not?

To inform about MTS that the transaction was successful or unsuccessful, setabort and set complete techniques are called from the object context object.

29. What do operating pointers in VBA mean?

Although the VBA (Visual Basic Information) has a wide range of uses, a function pointer has limitations. Because the Windows API only provides the ability to use an operation without providing any practical support for decision-making, it provides insufficient support for operation pointers. It is built-in support for the choice, but not for a request.

30. What does "Line Option Explicit" mean to you?

The dim statement does not specify any variables; therefore, the line explicit function forces the compiler to identify all such variables. such that the issue of type errors is much reduced by this command. Since VBA works with information-rich applications where type mistakes are frequent, this is used a lot.
