6 Cost Accountant Interview Questions and Answers

Q:

Describe a time in one of your previous jobs where attention to detail proved to be vital.

A:

Accounting is all about the details. Without getting the nitty-gritty aspects of a financial feasibility analysis right, the entire analysis might be worthless, and the project could potentially end up costing significantly more than anticipated. Finding a cost-accountant who excels at working with details is vital to the success of this role. A good candidate will both display attention to detail and understand its importance in getting the job done.

What to look for in an answer:

Revises analysis frequently
Ensures nothing was left unaccounted for
Thirsts for excellence

Example:

“I once went over my report and realized there were costs I hadn’t considered, but due to my careful attitude, I caught it before it became a real problem.”

Q:

How do you determine the selling price for a product?

A:

A cost accountant needs to find ways to recover the money lost in creating the product, which usually determines the minimum selling price. The candidate should give a detailed response to this question, making it clear that they have a system for deciding what the best selling price should be.

What to look for in an answer:

Possesses a clear process for determining a product’s selling price
Ensures the selling price will make up for the costs
Demonstrates prior experience

Example:

“I look at the current market trends and the cost of production and consider how much the typical consumer would be willing to spend.”

Q:

Describe a time in a previous job where your recommendation caused production to become more efficient.

A:

A good cost accountant will take a look at all expenses and find ways to cut them. For this reason, an eye for potential inefficiencies is something you should look for in any candidate. Look for someone who gives a clear and detailed answer to this question. If they can tell you exactly how much they saved their former employer, that’s even better.

What to look for in an answer:

Knows how to find problems in a system
Has an example from a previous job where they saved their employer money
Demonstrates they’re great at finding alternatives that are less costly

Example:

“I had my employer upgrade her machines to more energy-efficient ones, saving her thousands of dollars a year on power expenditures.”

Q:

What is your process for ensuring that all your work is correct?

A:

Since mistakes can be expensive in the cost accounting job, it’s important that your candidate have some method for catching mistakes early on. Look for a candidate with a clear process for finding any problems within their data or calculations. The candidate should be able to take you through all the steps in their procedure and should demonstrate that they take care with the details.

What to look for in an answer:

Is detail-oriented
Has a process for catching mistakes
Possesses confidence for accuracy and error-catching

Example:

“I like the accrual method because it seems to work well. I pore over all the data several times and make sure to do my calculations at least twice to ensure that debits and credits are balanced.”

Q:

Why do you think cost accounting is important?

A:

This question can give you an idea of your candidate’s passion and knowledge of the role. It can also give you a glimpse into their personality since their answer might give you an idea of why they chose to become a cost accountant in the first place. Ideally, look for a detailed and passionate answer and an explanation of what the importance of their role in your company is.

What to look for in an answer:

Passion about cost accounting
Understanding of the importance of the role as it relates to the entire business
Knowledge of the field

Example:

“To have a well-run business, you need to know how to eliminate unnecessary costs. Cost accounting is vital to being able to do that.”

Q:

What is a net incremental cash flow, and why is it important for a cost accountant to understand?

A:

When hiring a highly educated role like a cost accountant, you want to ensure the candidate has the necessary knowledge to perform the role appropriately. Asking basic questions about accounting and its terms is a good way to gauge whether the person interviewing for the job has the right level of education and experience for the position.

The candidate's answer should include:

A definition of net incremental cash flow
An explanation of its value
How this term applies to the company

A good answer might look like this example:

Example:

"Net incremental cash flow is a tool accountants use to evaluate potential cost savings or losses. In net incremental cash flow, we compare incoming cash flow to outgoing cash flow during the same time period. It's a valuable metric for making an educated and data-driven decision for making a purchase. So for this company, we could use net incremental cash flow to determine whether it's worthwhile to invest in a new fleet of trucks or repair and maintain the current vehicles the company has."
