Proficiency in variance analysis is a must-have for accountants, financial analysts, controllers and other roles involved in performance reporting and financial management. It’s no surprise that variance analysis is a common topic that comes up in interviews for these positions.

In this article, I’ll provide an overview of variance analysis and walk through the top 15 variance analysis interview questions you should prepare for. Mastering your responses to these questions is key to showcasing your skills and landing the job

What is Variance Analysis?

Let’s start with a quick primer on what variance analysis entails:

• Variance analysis compares actual results to budgeted or standard costs to identify and analyze deviations.

• Key variances examined include sales volume, material costs, labor costs, overhead costs and more.

• The goal is to pinpoint the root causes of variances, whether favorable or unfavorable.

• Findings from variance analysis are used to guide corrective actions and inform future budgeting.

• It relies on having accurate standard costs and budgets in place for comparison.

• Serves as a monitoring tool to identify potential issues early.

• Helps businesses maintain operational control and stay on track with financial goals.

Now that we’ve covered the basics, let’s get into the top interview questions on variance analysis that you should be ready for:
