Analyst/Associate Investment Banking Interview Questions
Problem Solving Questions (5 minutes):
This section of the investment banking interview questions provides insight into the candidate’s critical thinking skills.
Question – 1
“How many hairstylists or barbers do you estimate are there in this city? Explain your logic/assumptions?”
Answer: Explain the logic based on the population of the city, the average number of cuts people have per year, the number of cuts one barber can do per year, and thus, how many that implies there must be. (e.g., 2 million people, each get an average of 4 cuts per year, which results in 8 million cuts per year. Each barber works an average of 8 hours per day, times five days per week, times fifty weeks per year equals 2,000 hours of cutting time per year. Each haircut takes 1 hour. Thus, 8 million haircuts, equal 8 million hours, divided by 2,000 hours per barber requires 4,000 barbers in the city.)
Question – 2
“In the middle of a pond is a single lily pad; the lily pad doubles in size every day and the pond is completely covered on the last day of the month (30 days). How long does it take for the pond to be half-covered?”
Answer: 29 days, because if it doubles in size each day it also halves each day. Thus at 29 days is half full in order to be completely full in 30 days.
Question – 3
“A windowless room contains three identical light bulbs. Each light is connected to one of three switches outside of the room. Each bulb is switched off at present. You are outside the room, and the door is closed. You have one, and only one, opportunity to flip any of the external switches. After this, you can go into the room and look at the lights, but you may not touch the switches again. How can you tell which switch goes to which light?”
Answer: Switch on switches 1 & 2, wait a moment and switch off number 2. Enter the room. Whichever bulb is on is wired to switch 1, whichever is off and hot is wired to switch number 2, and the third is wired to switch 3.
TECHNICAL KNOWLEDGE QUESTIONS (15 – 20 MINUTES):
This section of the investment banking interview questions provides insight into the candidate’s technical knowledge of finance, accounting, valuation, and financial modeling.
Question – 1
“Please walk me through the three financial statements.”
Answer : The balance sheet is a snapshot at a point in time. On the top half you have the company’s Assets and on the bottom half its Liabilities and Shareholders’ Equity (or Net Worth). The assets and liabilities are typically listed in order of liquidity and separated between current and non-current.
The income statement covers a period of time, such as a quarter or year. It illustrates the profitability of the company from an accounting (accrual and matching) perspective. It starts with the revenue line and after deducting expenses derives net income.
The cash flow statement has three sections: cash from operations, cash used in investing, and cash from financing. It can be calculated using the direct approach or the reconciliation approach. It “undoes” all of the accounting principles and shows the cash flows of the business.
Question – 2
“How would you value a company?”
Answer : There are three common valuation methods used in IB:
1) The multiples approach (also called “comps”), in which you multiply the earnings of a company by the P/E ratio of the industry in which it competes (and other ratios).
2) Transactions approach (also called “precedents”), where you compare the company to other companies that have recently sold/been acquired in that industry.
3) The Discounted Cash Flow approach, in which you discount the values of future cash flows back to the present.
Question – 3
“You have the opportunity to purchase a series of future cash flows that are $200 in perpetuity. The total cost of capital is 10%, how much are you prepared to pay today?”
Answer : [Note: Value = Cash Flow / WACC].
$2,000, because: $200 / 10% = $2,000 (i.e. 10x)
Question – 4
“When should a company consider issuing debt instead of equity?”
Answer: There are many reasons to issue debt instead of equity: (1) It is a less risky and cheaper source of financing compared to issuing equity; (2) If the company has taxable income, issuing debt provides the benefit of tax shields; (3) If the firm has immediately steady cash flows and is able to make their interest payments; (4) higher financial leverage helps maximize the return on invested capital; (5) when issuing debt yields a lower weighted cost of capital (WACC) than issuing equity.
Question – 5
“List the main components of WACC (i.e. Weighted Average Cost of Capital).”
Answer: Debt, Equity, Tax, Beta. See more on WACC here.
Question – 6
“How do you calculate the WACC?”
Answer: This is calculated by taking the proportion of debt to total capital, times the debt rate, times one minus the effective tax rate, plus the proportion of equity to capital, times the required return on equity.
Question – 7
“Which is cheaper debt or equity? Why?”
Answer: Debt because: It is paid before equity / may have security. Ranks ahead on liquidation. Tax saving etc.
Question – 8
“What is the average Price/Earnings PE ratio for the S&P 500 Index?”
Answer: About 15-20 times, the PE ratio varies by industry and period in the cycle.
Question – 9
“A company has learned that due to a new accounting rule, it can start capitalizing R&D costs instead of expensing them“.
Part a) What is the impact on EBITDA?
Part b) What is the impact on Net Income?
Part c) What is the impact on cash flow?
Part d) What is the impact on valuation?
Part a) EBITDA increases by amount capitalized;
Part b) Net Income increases, the amount depends on depreciation and tax treatment;
Part c) Cash flow is almost constant – however, cash taxes may be different due to the depreciation rate
Part d) Valuation is constant – except for cash taxes impact/timing on NPV
Question – 10
“What happens to Earnings Per Share (EPS) if a company decides to issue debt to buy back shares?”
Answer: Issuance of debt increases after-tax interest expense which lowers EPS.
Repurchase of shares reduces the number of shares outstanding which increases EPS.
Whether it increases or decreases EPS depends on the net impact of the above two points.
Question – 11
“What makes a good financial model?”
Answer : Building a financial model takes a lot of practice to be really good at it. The best financial models are clearly laid out, identify all the key drivers of the business, are accurate and precise yet not overly complicated, can handle dynamic scenarios, and have built-in sensitivity analysis and error checking.
