Before the Spring Festival, McKinsey, Bain and Boston Consulting were released in various official micro-summer internship positions, but until now, MBB2020 summer internship online application channels are already closed. (: This means that the spring move started not far away ...)
Each company in general after the application deadline of a few days or a week will begin the written / interview. Bain has been clearly stated in mid-pen interview this month:In the official notice of McKinsey and Boston, has posted the official requirements and interview preparation materials, we must look carefully in advance to:
The data show that the number of applicants each recruitment season MBB are as high as 200,000, but 86% of the candidates were washed off in the Case Interview session, eventually admitted less than 2,200 enrollment rate was only 1%! So do not practice Case advance, basically cold.
I want to go to MBB, Case how to practice?
As a consulting firm signs a compulsory item, in consultation with the interview process, Case Interview regarded as routine deepest, the most critical aspect, and is mainly used to examine the candidates logical thinking, business acumen and quantitative thinking.
In fact, Case Interview is the scene of a business analysis of interview questions. Generally 1V1, there will be two round Case Interview, by two different interviewers to be responsible, each Interview for 45 minutes.The Marketing Sizing is the case will interview questions, get to know those kinds of customs clearance solution for consulting interview is very important Oh, topics are as follows:Shanghai, a total number of birds?
Problem-solving ideas are as follows:
Ask yourself: Where birds? Nest trees green zoo, family aviculture, parks and forests: the answer. Think again: Where is most of the birds? Nest trees of green parks and forests: the answer.
= Number of bird nest × birds / nest, assuming a bird nest about 3-5: Birds / nest = 4. Thus , the problem lies next nest: nest = × nest tree / tree, if there is a nest 10 per tree: nest / tree = 0.1, Note: trees is here that the nest can hold high trees, small shrubs can not oh.Then, the next key is tree: Tree Tree area × = green / green area unit. First solve the green area: the total area of urban green area = × greening ratio, the Shanghai taxi from People's Square (city center) to the Pudong Airport (the city boundary) distance is about 40km: Shanghai total urban area = π × 40 × 40≈5000 square kilometers. Greening rate: high school geography through urban greening China is generally between 10% -20%: greening rate = 15%Then solve <tree / green area per unit> , to know how many green trees per square kilometer, get to know the tree spacing accurate to say that the distance between the high trees to accommodate the nest. Assumptions and roadside parks and forest trees in the distance an average of five meters. Tree / unit area green = (1000m / 5m) × ( 1000m / 5m) = 40000 trees / km.= The number of birds birds nest × / × nest nest = tree / tree Bird × / × tree nest = green area / unit area green nest × / × tree birds / nest = total area of urban green rate × × tree # / unit area green nest × / × tree birds / nest = 5000 km2 tree × 15% × 40000 / km × 0.1 × 4 = 12,000,000 birds.
Market Sizing the problem is really so easy to solve it?
Not just a consulting firm, well-known companies in the interview process, both in the study of market capacity problem because it is an entry-level, and can be seen phenomenal job seekers: Market Insight + + core issue of communication and expression of logical deduction!Interestingly, when the sister school and two users to communicate ideas to answer Zhenti, the situation was out of control
Why interviewer love to test the market size of the problem?
One reason: on the estimated size of the market, is the industry elite are essential market insight, whether the ability to be able to see through the phenomena of nature. In this session, candidates need for a strange question, quickly develop a solution whereby the interviewer see you in the accumulation of Business.Two reasons: the estimated market size is accurate, not only to study the market insight, also examines careful thinking and logical deduction capabilities of the candidates. Criterion is whether a candidate can put aside the calculator accurately estimate the answer, as well as strong support logic can provide for their own assumptions. Among them, the interviewer study is to calculate the candidate's ability and sensitivity to numbers.Three reasons: some industries are too small congregation, could not find secondary data. See more information visit the market scale mining capabilities of the candidates. As society advances, more and more industries appear. No predecessors trees, only yourself. For example Wolfberry, artichokes, dates, gelatin and other health care products. But customers need to, you can not guarantee that this market is really not worth studying, so you still need to go to the market to model estimates.This inspection logic is also used in the work up. This also explains why consulting firms have to test this type of problem.
