Welcome!
My name is Ben Gutkovich and I’m the founder of ConsultingCase.Pro and the creator of the QuantMaster™ Ace the Interview Math Online Course. I’m a former McKinsey and Strategy& (PwC's Strategy Consulting arm) manager and interviewer, and an MBA graduate of London Business School.
Over the past 3 years, I've coached 1000+ job candidates for consulting, finance and tech positions, and saw that many of them struggled to execute math calculations quickly and accurately. Interviewers use quantitative questions as a proxy for candidate's mental agility, and if you make mistakes and show lack of understanding of basic math concepts, you will not get the job, no matter how well you do in other parts of the interview.
I created this online course to teach you the quantitative and exhibit reading skills you need to succeed in interviews for top tier firms across industries. In this course, you will learn a comprehensive set of calculation methods designed specifically to enable you to perform Interview Math calculations quickly and easily, as well as get lots of practice in the most typical quantitative Interview problem types.
This course is suitable for aspiring management consultants preparing for Case Interviews, as well as candidates for many other job functions such as Product Management, Marketing, General Management, Private Equity, and Brand Management, at firms like Google, Facebook, Goldman Sachs, Amazon, and many others.
QuantMaster™ Ace the Interview Math is unique among quantitative Interview preparation resources because it uses on-demand video lessons to teach efficient calculation and problem-solving methods — instead of simply providing practice problems and answers. Furthermore, all the calculation methods and examples are based on questions used in actual Interviews.
After learning the course material, candidates will dramatically increase their calculation speed and efficiency, and be well prepared for a wide range of quantitative Interviews questions.
Hundreds of students from leading universities worldwide, like Wharton, Harvard Business School, Stanford, MIT, Kellogg, London Business School, INSEAD, and many more, have used the QuantMaster™ Ace the Interview Math methods and techniques to join top-tier firms like McKinsey, Bain, BCG, Accenture, Deloitte, PwC, Google, Amazon, and Goldman Sachs.
