OW的面試分為三個流程：
Step 1為Conversational Interview
Step 2 為Case Interview
Step 3為Final Interview。
其中最關(guān)鍵的還是Case Interview，
OW的官網(wǎng)有面試案例參考及練習
建議想要申請的同學(xué)練習一下，OW家的面試風格比較獨特，會有比較多的算術(shù)。
以下是OW官網(wǎng)的兩個案例截取。
WUMBLEWORLD
a theme park operator located in a wealthy coastal city in China.
Background information
Our client is WumbleWorld, a theme park operator located in a wealthy coastal city in China. WumbleWorld is a 50/50 joint venture between a foreign firm and a China state-owned enterprise. The company manages a single park year-round and principally generates revenues from park admissions, food and beverage, and merchandise.
WumbleWorld's CEO has asked Oliver Wyman to identify the reasons for her company's declining profits and develop suggestions for how to reverse this trend.
QUESTION 1
Your team leader suggests that you conduct a high-level brainstorming session. What general information would you like to gather to help you with this case?
ANSWER
A few possible areas for research are listed below. Understanding these important foundations can be helpful in formulating and structuring a good answer.
Industry
What are the general trends? What, if any, innovation has taken place? What is the structure, size, and growth rate of the industry? In what stage of its life cycle is the industry (e.g., emerging, maturity, decline)? Have any merger or acquisitions taken place? Do any barriers to entry or exit exist? What role does government play in its regulation?
Competition
Who are the major players and what are their relative market shares? Are there any new entrants?Customers
What is the customer breakdown in terms of income, demographics, geography, etc.? How is consumer behavior changing？
Company
What is the company's position within the industry? How is the company structured? Have there been any recent changes within the company? What do the firm's financials look like? Is the joint venture structure functioning?
Suppliers
How many suppliers exist? What are the conditions in their market? Are the supplier relationships controlled by the Chinese side to the joint venture? How transparent are they?
QUESTION 1a
Your team has been asked to address profitability. How would you structure your investigation into WumbleWorld's weakening profitability?
ANSWER
The diagram below depicts one way of breaking down the proposed problem.
QUESTION 2
Your team has chosen first to explore fixed costs. Please identify some of WumbleWorld's fixed costs and explain why they may or may not be changing.
ANSWER
Fixed costs are those that would not change as a function of the number of park visitors. As demonstrated in the graph below, the main buckets of fixed costs are:
QUESTION 3
You have found that fixed costs have been fairly constant and, as such, are unlikely to be contributing to weakening profits. The team has decided to investigate variable costs. Please list a few of WumbleWorld's major variable costs.
ANSWER
Variable costs change with the number of units that are sold. The following buckets of costs are dependent on the number of park visitors each day:
Variable labor
cleaning crew, ticket counters, ride facilitators, general staff
Cost of goods sold (COGS)
food, beverage, merchandise
Utilities
electricity, fuel
Other
park maintenance, taxes
The client has again provided your team with additional data. WumbleWorld's breakdown of variable costs are shown below.
QUESTION 4
Your team has determined that labor is the key cost driver. WumbleWorld's variable labor costs over the past 5 years are presented below. What conclusions can you draw about WumbleWorld's variable
labor cost trends?
ANSWER
Variable labor costs on a per-visitor basis have remained constant and thus are not likely the cause of the downward trend in profitability.
At first glance, you may have thought that variable labor costs declined. This is only true on an aggregate basis. As fewer people have visited the parks, labor costs have fallen. If you divided the total labor costs by the number of visitors each year, you would see that the per-visitor labor cost is approximately 30 CNY in most years.
(Note: The per-visitor labor costs in 2009
did not equal 30 CNY due to a lag in labor reduction. WumbleWorld was not able to adjust its labor force quickly enough to match the sharp decline in the number of visitors.)
QUESTION 5
Given that costs are likely not the cause of the decline in profitability, your team has decided to examine WumbleWorld's revenues. Displayed below is the per-customer breakdown and value of revenue for WumbleWorld and its competitor, MightyMountain. Neither company has any additional revenue streams. What insights can you draw from these graphs?
ANSWER
The following insights about revenue can be drawn from the graph:
WumbleWorld's average daily spend per visitor has been relatively constant.
It appears that WumbleWorld has not been as successful as MightyMountain at converting admissions into merchandise and food
& beverage sales.
MightyMountain reduced its admission price between 2008 and 2011.
This led to a decrease in total average daily spend per visitor, but increased food & beverage and merchandise spend per visitor. MightyMountain's price decrease likely contributed to an increase in the number of visitors, which might explain the significant decline in the number of WumbleWorld visitors between 2008 and 2009 (as displayed in a previous chart).
Volume (number of park visitors) seems to be a key driver of revenue.Though the relative profitability is unknown, MightyMountain's decision to reduce prices hints that its strategy hinges upon increasing the number of visitors to its parks and increasing average visitor spend on food & beverage and merchandise。
QUESTION 6
Your team has decided to first focus on the number of visitors and then hone in on average spend per visitor to drive profitability forward. To better understand the drivers of park attendance, the team has chosen to analyze WumbleWorld's consumer market. Specifically, the objective is to divide visitors into groups of people with similar characteristics. How might you group customers in this market? What metrics would you use?
ANSWER
The market may be segmented using a number of different metrics, including (but not limited to) demographics, income level, geography, spending behavior within the park, activities within the park, and cost of customer acquisition.
QUESTION 7
Oliver Wyman has conducted a thorough analysis of the various consumer segments in this market. Most of WumbleWorld's visitors align with one of the three segments listed below. Which of
WumbleWorld's customer groups is the largest.
(in terms of total number of visits annually)?
ANSWER
To determine the largest segment (in terms of total number of visits annually), multiply the total people in segment by WumbleWorld's penetration rate by # of visits/person annually. The results of these calculations is shown below, revealing that the family segment is largest.
面試經(jīng)驗總結(jié)
1. 面試過程中要relax！這樣做case的時候就不會太緊張。
- 做OW的case有很多數(shù)據(jù)，所以大家要好好練習。
- 看一本casebook其實就夠了，因為內(nèi)容大同小異，而且書里的都是很基礎(chǔ)的問題，面試官最后肯定會想招術(shù)來嚇唬你。平時多積累一點商業(yè)知識，然后冷靜地臨場發(fā)揮。
2. OW的官網(wǎng)中會給出很多有用的信息，最好在面試前認真地看一遍他們家的官網(wǎng)內(nèi)容，對于case也會比較有幫助。
3. 若case有覺得疑惑的部分可以直接問面試官，比如是否有更詳細的信息之類的問題。如果你不問，面試官會默認為你已經(jīng)知道了。而且面試官最后也有可能利用你疑惑的部分而反問你。
