Mc. Kinsey Problem Solving Test PSTHint Bookmark This Page Its LongThe Mc. Kinsey Problem Solving Test also known as the Mc. Kinsey PST is a math computation, data interpretation and logical thinking test used by Mc. Kinsey to determine which candidates are granted a first round case interview. In general, candidates whose resumes Mc. Kinsey deems acceptable are invited to take the test. Based on feedback from hundreds of test takers, you must pass the test in order to get the interview. There are few to no exceptions to this rule. Why the Mc. Kinsey PST Exists. Snooper S7000 Truckmate User Manual'>Snooper S7000 Truckmate User Manual. The reason Mc. Kinsey uses the test is because there are a certain set of numerical computation and logical thinking skills required to be successful in consulting. While standardized math tests like the quantitative sections of the SAT, GRE, or GMAT do test math computational skills, it is possible to get perfect scores on these math tests but fail on the job in consulting. Its my interpretation that Mc. Kinsey developed the Mc. Kinsey Test in order to test those skills that regular math tests do not adequately evaluate. In particular, these skills involve data interpretation and critical numerical reasoning.

Now when I hear the words data interpretation and critical numerical reasoning, it always reminds me of those college entrance exam tests that were challenging, seemingly arbitrary and pretty much not useful in the real world. But, it turns out these skills actually have a very practical purpose while working as a consultant. These skills allow you to 1 Read a graphical chart or the data spreadsheet that was used to create the chart2 Grasp what the data is conclusively telling you and separate from what the data is suggesting but not definitively so3 Write a 1 2 sentence headline at the top of a Powerpoint slide state a logically correct conclusion. In other words, you end up using these skills every single day as a consultant. And if you use these skills incorrectly, then either your manager or partner has to redo your work for you which means at some point you will get fired or the client notices the logical flaws in your work and it makes your firm, your partner and your manager look bad and of course means that at some point youre going to get fired. Now you would think looking at a chart and writing a powerpoint headline is not a very difficult skill. Homework help through online websites.

I mean anyone can look at a chart and write a headline, but you would be surprised by how many people actually get the headline wrong. In other words, a LOT of aspiring consultants and even some first year consultants see that data and come to the WRONG conclusion. From a Mc. Kinsey partners point of view, its a complete disaster if someone on your team lacks this skill. THINKS he has the skill, but actually doesnt. It is such a big deal that Mc. Kinsey has gone to extensive effort to create this test and have thousands of candidates around the world take this problem solving test. All of this effort is taken for the sole goal of hiring new consultants who can do 1 do math accurately, 2 do it quickly, and most importantly interpret data CORRECTLY. In short, being able to solve problems logically is a BIG DEAL. Mc. Kinsey PST Format. The computer based test consists of approximately  2. No business background is needed to take the test, but being familiar with a few commonly used business terms is useful see the Mc. Kinsey PST Frequently Used Terms section of Part II of this Guide Below. You are permitted to use pen, pencil or paper. No calculators or computing devices are permitted. Typically a graphical chart or table of numerical data is presented along with some descriptive text about a company or industry. The two most problem question types are 1 Math Word Problem Given the data in Table X, calculate A, B or C. A, B or C might be profit margins. It might be figuring out which companys profits were larger two years ago. It might be calculating the difference in sales from today vs 2 years ago for two different companies and figuring out which company had the bigger change. In the US, we call these word problems. The purpose of these problems is to give you raw data and information conveyed in a text paragraph, and see if you can figure out the math equation needed to solve the problem. Often the actual math computation isnt difficult its just addition, subtraction, multiplication or division often math problems are based on percentages growth rate, cost expressed as a percentage of sales, or profits as a percentage of sales, sales of this year vs 3 years ago expressed as a percentage. What makes the word problem difficult is a Time, b Time, c Time. Amongst those who pass the Mc. Kinsey Problem Solving Test, the consistent feedback was they finished with barely enough time. The most common reasons for making a mistake for a math word problem is misreading, misunderstanding, or misinterpreting the data presented or what the question was asking. The other big reason is computational error. When I took my first Mc. Kinsey PST practice test, I actually missed several problems. To be fair, I had a newborn baby in the house and was sleeping 3 hours a night at the time, and I made a LOT of careless errors. My mistakes I thought they were asking one thing, when they were really asking another. I rushed the computation, and made mistakes. Unlikely Lover Diana Palmer Pdf here. Data Interpretation Given X chart, which of the following conclusions are accurate The other type of question isnt computationally intensive, but rather tests your logic and critical reasoning skills. You will be asked to refer to a chart or data table mini spreadsheet with numbers and asked some variation of the question Which conclusion is correct Variations of this question including presenting you with potential answers that are a definitively correct, b could be correct but you cant be 1. The answers that are trickiest are ones that seem consistent with the data, but is NOT completely conclusive. In other words, you need to be able to look at the data and tell the difference between a factual conclusion vs. NOT 1. 00 proven by the data. Tips for Passing the Mc. Kinsey PSTSkim the questions FIRST to get a feel for what you will be asked, THEN read the data table or chart. This allows you to get some idea of what you should be paying attention to while you look at the data or read the text. Read the text descriptions and the questions VERY CAREFULLY. Take the questions literally. I made the mistake of assuming some of the questions were commonly used business analysis and jumped ahead to calculate what I assumed they were asking. What I should have done was look at what they were LITERALLY asking and just answer what they asked. If your math computation skills are rusty, practice your math accuracy and speed. You do not have a lot of time to double check your computations on every problem. Some people dont have time to double check their computations at all. The more youre absolutely certain your math skills are accurate and quick, the more time youll have to actually answer all the questions. Once again, the main enemy of the test is timeFor data interpretation drawing a conclusion type questions, be careful of the multiple choice answer options that seems consistent with the data, but are not 1. The easiest way to do this is to immediately eliminate the answer options that are clearly wrong. Then BE CAREFUL in looking at the remaining options. Computational geometry Wikipedia. Computational geometry is a branch of computer science devoted to the study of algorithms which can be stated in terms of geometry. Some purely geometrical problems arise out of the study of computational geometric algorithms, and such problems are also considered to be part of computational geometry. While modern computational geometry is a recent development, it is one of the oldest fields of computing with history stretching back to antiquity. Computational complexity is central to computational geometry, with great practical significance if algorithms are used on very large datasets containing tens or hundreds of millions of points. For such sets, the difference between On. On log n may be the difference between days and seconds of computation. The main impetus for the development of computational geometry as a discipline was progress in computer graphics and computer aided design and manufacturing CADCAM, but many problems in computational geometry are classical in nature, and may come from mathematical visualization. Other important applications of computational geometry include robotics motion planning and visibility problems, geographic information systems GIS geometrical location and search, route planning, integrated circuit design IC geometry design and verification, computer aided engineering CAE mesh generation, computer vision 3. D reconstruction. The main branches of computational geometry are Combinatorial computational geometry, also called algorithmic geometry, which deals with geometric objects as discrete entities. A groundlaying book in the subject by Preparata and Shamos dates the first use of the term computational geometry in this sense by 1. Numerical computational geometry, also called machine geometry, computer aided geometric design CAGD, or geometric modeling, which deals primarily with representing real world objects in forms suitable for computer computations in CADCAM systems. This branch may be seen as a further development of descriptive geometry and is often considered a branch of computer graphics or CAD. The term computational geometry in this meaning has been in use since 1. Combinatorial computational geometryeditThe primary goal of research in combinatorial computational geometry is to develop efficient algorithms and data structures for solving problems stated in terms of basic geometrical objects points, line segments, polygons, polyhedra, etc. Some of these problems seem so simple that they were not regarded as problems at all until the advent of computers. Consider, for example, the Closest pair problem Given n points in the plane, find the two with the smallest distance from each other. One could compute the distances between all the pairs of points, of which there are nn 12, then pick the pair with the smallest distance. This brute force algorithm takes On. A classic result in computational geometry was the formulation of an algorithm that takes On log n. Randomized algorithms that take On expected time,3 as well as a deterministic algorithm that takes On log log n time,4 have also been discovered. Problem classeseditThe core problems in computational geometry may be classified in different ways, according to various criteria. The following general classes may be distinguished. Static problemseditIn the problems of this category, some input is given and the corresponding output needs to be constructed or found. Some fundamental problems of this type are The computational complexity for this class of problems is estimated by the time and space computer memory required to solve a given problem instance. Geometric query problemseditIn geometric query problems, commonly known as geometric search problems, the input consists of two parts the search space part and the query part, which varies over the problem instances. The search space typically needs to be preprocessed, in a way that multiple queries can be answered efficiently. Some fundamental geometric query problems are Range searching Preprocess a set of points, in order to efficiently count the number of points inside a query region. Point location Given a partitioning of the space into cells, produce a data structure that efficiently tells in which cell a query point is located. Nearest neighbor Preprocess a set of points, in order to efficiently find which point is closest to a query point. Ray tracing Given a set of objects in space, produce a data structure that efficiently tells which object a query ray intersects first. If the search space is fixed, the computational complexity for this class of problems is usually estimated by the time and space required to construct the data structure to be searched inthe time and sometimes an extra space to answer queries. For the case when the search space is allowed to vary, see Dynamic problems. Dynamic problemseditYet another major class is the dynamic problems, in which the goal is to find an efficient algorithm for finding a solution repeatedly after each incremental modification of the input data addition or deletion input geometric elements. Algorithms for problems of this type typically involve dynamic data structures. Any of the computational geometric problems may be converted into a dynamic one, at the cost of increased processing time. Site Pour Telecharger Livres Pdf Gratuit here. For example, the range searching problem may be converted into the dynamic range searching problem by providing for addition andor deletion of the points. The dynamic convex hull problem is to keep track of the convex hull, e. The computational complexity for this class of problems is estimated by the time and space required to construct the data structure to be searched inthe time and space to modify the searched data structure after an incremental change in the search spacethe time and sometimes an extra space to answer a query. VariationseditSome problems may be treated as belonging to either of the categories, depending on the context. For example, consider the following problem. In many applications this problem is treated as a single shot one, i. For example, in many applications of computer graphics a common problem is to find which area on the screen is clicked by a pointer. However, in some applications the polygon in question is invariant, while the point represents a query. For example, the input polygon may represent a border of a country and a point is a position of an aircraft, and the problem is to determine whether the aircraft violated the border. Finally, in the previously mentioned example of computer graphics, in CAD applications the changing input data are often stored in dynamic data structures, which may be exploited to speed up the point in polygon queries. In some contexts of query problems there are reasonable expectations on the sequence of the queries, which may be exploited either for efficient data structures or for tighter computational complexity estimates. For example, in some cases it is important to know the worst case for the total time for the whole sequence of N queries, rather than for a single query. See also amortized analysis. Numerical computational geometryeditThis branch is also known as geometric modelling and computer aided geometric design CAGD. Core problems are curve and surface modelling and representation. The most important instruments here are parametric curves and parametric surfaces, such as Bzier curves, spline curves and surfaces.
