15 Investment Banker Interview Questions and Answers

How can you value a company?

The aim of this question is to assess the candidate's technical knowledge of valuation. What to look for in a successful answer:

  • Knowledge of different valuation methods
  • Experience with valuation
  • Understanding of when to use each valuation method

Here's an example of a strong answer:

Example:

"There are plenty of ways to value a company, but the two primary methods are to look at the company's discounted cash flow variation and relative valuation. Analyzing the discounted cash flow of a company will give me an estimate of its current value based on the amount of money it will earn in the future. Relative variation compares one company's value to its competitor to assess its worth. Neither method is concrete as the company's value will vary as it grows."

Do you know what the three types of financial statements are?

The aim of this question is to assess the candidate's knowledge of financial statements and what each one is for. What to look for in a successful answer:

  • Knowledge of the three financial statements
  • Understanding of when to use each statement
  • Experience using or creating the statements

Here's an example of a strong answer:

Example:

"The three financial statements include a balance sheet, cash flow statement and income statement. A balance sheet shows the company's assets, liabilities and net worth. The cash flow statement shows cash from three activities: operations, investing and financing. An income statement shows how much the company earned over a period of time, such as quarterly or annually."

Is the cost of debt or equity higher? 

The aim of this question is to gauge the candidate's financial knowledge of debt and equity. What to look for in a successful answer:

  • Understanding of debt and equity
  • Correct knowledge of which is cheaper
  • Experience with debt and equity financing

Here's an example of a strong answer:

Example:

"The cost of equity tends to be higher than debt. This is because, in the case of liquidation or bankruptcy, debt is paid before equity. Interest rates for debt also tend to be lower, and it is tax-deductible, saving the company money on their income taxes."

Would you recommend a company to issue debt or equity?

The aim of this question is to assess the candidate's ability to make smart financial decisions for your company. What to look for in a successful answer:

  • Ability to choose between debt or equity financing
  • Strong decision-making skills
  • Understanding of debt versus equity financing

Here's an example of a strong answer:

Example:

"As debt tends to be cheaper than equity, I often recommend companies to use debt financing instead of equity financing. Issuing debt is less risky and is a cheaper method of financing. It also creates a tax shield, allowing the company to deduct the interest they pay from their taxes. Debt financing also gives your company more freedom. Lenders won't tell you what to do with the money or how to run your company. Equity financing requires you to have investors that will have a say in decisions your company makes."

Why did you pursue a career in investment banking?

The aim of this question is to gauge the candidate's reasoning behind becoming an investment banker to see if they're passionate about the work. What to look for in a successful answer:

  • Passion for the finance industry
  • Commitment to the role
  • Understanding of what an investment banker is and what they do

Here's an example of a strong answer:

Example:

"I was always interested in finance, which is why I pursued a major in the field, but I wasn't sure what I wanted to do with it. I interned at a bank while I was in university and met people in various roles. The few investment bankers I met introduced me to the role, and it immediately intrigued me as I love investing and learning more about the best techniques and methods."

What would you say an investment banker does?

Example:

"An investment banker helps organisations raise money through investments or by borrowing. Investment bankers may also research the market to advise companies about what the best financial decisions are. They may also manage a company's assets or assist a financial team with doing so."

What qualities do you have that make you a good investment banker?

Being able to communicate with anyone easily helps me make lucrative deals that benefit my clients.

  • Strong problem-solving skills
  • Ability to work well under pressure

Example:

"My previous company was trying to land a client that could help us earn over a million dollars a year, so it was a big deal. I was the main point of contact with the client, so I did most of the negotiating. I spent months building a relationship with the client so they knew they could trust us. After a lot of back and forth, we landed the client."

Do you want to stay in investment banking long-term?

The aim of this question is to determine whether the candidate would be a good fit for your company long term. What to look for in a successful answer:

  • Willingness to stay with one company long term
  • Understanding of the role
  • Experience in a similar role

Here's an example of a strong answer:

Example:

"I have worked hard to become an investment banker and really enjoy the work, so I would like to stay in investment banking long term. I think working for a bigger company, such as yours, for a long time will help me learn even more about the industry and build a bigger client base."

What is the Weighted Average Cost of Capital (WACC)?

The aim of this question is to assess the candidate's knowledge of common financial terms and calculations. What to look for in a successful answer:

  • Understanding of financial terms
  • Experience using this calculation
  • Knowledge of when to use this calculation or others

Here's an example of a strong answer:

  • Strong written and verbal communication skills
  • Ability to independently make decisions
  • Willingness to research investments

Here's an example of a strong answer:

Example:

"Before advising anyone to invest in anything, I would thoroughly research it myself. While researching, I would compile convincing evidence towardss investing, such as an estimate of how much you could earn. I would deliver this information in a presentation and list the pros and potential cons of the investment to help you make an informed decision. If my research shows that the investment isn't worth it, I wouldn't try to convince you it was as I value honesty and integrity."

  • Knowledge of the finance industry
  • Ability to explain investment and commercial banking
  • Confidence in their knowledge

Here's an example of a strong answer:

Example:

"Commercial banking is for customers to store and access their money, as well as receive loans or interest from their deposits. Investment banking does not deal with customers, but organisations and investors instead. Investment banks focus on selling investments and holding debt and equity from banks."

When would you recommend a company merge with another one?

  • Knowledge of mergersand acquisitions
  • Ability to decide if a company should merge with another
  • Experience handling mergers or acquisitions

Here's an example of a strong answer:

Example:

"I would recommend a company merge with another one if it's a good financial decision for both parties. For example, a smaller company merging with a larger one will benefit from their resources and client base, allowing them to expand. The larger company will benefit from the extra income."

How can you calculate the cost of equity? 

The aim of this question is to gauge the candidate's knowledge of financial terms and calculations. What to look for in a successful answer:

  • Understanding of equity

The aim of this question is to gauge whether the candidate understands the common challenges associated with the role and how to overcome them. What to look for in a successful answer:

  • Strong problem-solving skills
  • Previous experience in a similar role
  • Understanding of common investment banking challenges

Here's an example of a strong answer:

Example:

"A lot of the challenges I faced in previous roles were ones out of my control, such as market fluctuation and cyber attacks, any reason for the stock market to drop. Trying to help the company come back from those losses was difficult, as many of my colleagues wanted to pull our investments right away. I suggested otherwise, so we kept most of our investments and waited for the stock market to stabilise again, allowing us to earn back our money."
