excel vba interview questions

Visual Basic for Applications (VBA) is an Excel programming language that allows users to create automated data processing functions and generate data visualizations, such as charts or graphs. Having knowledge and experience using VBA can demonstrate your technological skill for employers and help you answer technical interview questions. Understanding what questions an interviewer might ask you about VBA may help you prepare for your next job interview. In this article, we discuss VBA interview questions, explain why an interviewer might ask them and provide sample answers to guide you.

Why would you use VBA to dial a phone number?

You can use VBA language within a spreadsheet to call phones. This can be a useful function for a variety of reasons, and interviewers may ask this question to know if youve ever used that function and how. Consider a scenario where youve wanted or needed to call phone numbers directly from a spreadsheet. Describe why this function may improve or optimize your workflow processes.

Example: “Some work tasks may require calling clients or consumers listed on a spreadsheet. Rather than manually dialing each phone number on a separate device, using a shell command through VBA saves time and allows me to call people directly. Using VBA to automatically dial a phone number saves time and minimizes dialing errors to speed up my work tasks.”

How do you classify data types in VBA?

An interviewer might ask you this to test your knowledge on industry terminology and VBA specific jargon. Knowing variable level vocabulary allows you to understand project directions and document or relay information accurately in reports or to superiors. There are two main classifications of data types in VBA and several in each category. List the data types that you know and provide a brief explanation of them.

Example: “The two categories of VBA data types are numeric and non-numeric. Users can manipulate numeric data types like bytes, integers, currencies and decimals to perform arithmetic functions. Non-numeric data types like dates, strings, objects or boolean cant perform those same functions. These data types inform computer operating systems about the data its storing and what functions its capable of.”

How would you define variable levels?

Variable levels feature different accesses and functions within VBA programming. Understanding these levels allows you to receive directions and work on the appropriate level to accomplish your task. There are three main levels in VBA that you can list and briefly explain. Interviewers may ask this question to understand how you view the importance of each level and how they may be necessary.

Example: “The three main variable levels which are the local, module and global levels. Each level provides users with different access, which ensures that code remains consistent. The local level features variables defined with DIM statements, while the module level has variables defined with a DIM statement on top of a module. The global level features variables defined by public statements on top of any module.”

Comments are used to document the program logic and the user information with which other programmers can work seamlessly on the same code in future. There are mainly two methods in VBA to represent comments.

In VBA, variable can be declared with the keyword “DIM” while constant is declared with keyword “Const.”

22) Mention how can you comment and uncomment blocks of code in the office VBA editor?

“Option Explicit” makes the declaration of variables mandatory. Line explicit function makes the compiler to determine all the variables that are not declared by the dim statement. This command diminishes the problem of type errors significantly. It is used in VBA because it deals with information rich application in which type errors are common. Before starting any, sub-procedures it can be used inside a module.

To find the last row in a column, the command used is End(xlUp) and to find last column in a row, the command used is End(xlToLeft).
