There's something I forgot to tell you / by Lewis Lin

So I forgot to tell you something.

That's right. I launched another book. It's called Interview Math. And I'm grateful that it's skyrocketed up to the top 1% of all books sold on Amazon.com.

(The Europeans love it a lot. Go figure.)

What is Interview Math?

Interview Math are those pesky quantitative case interview questions. Stuff like: 

  • Market Sizing: Estimate the total industry wide sales of lipstick in the U.S. 
  • Revenue Estimate: Estimate annual sales of Starbucks' retail stores in the United States. 
  • Price Elasticity: The price of a one-way ticket from Seattle to New York is $400. Should JetBlue raise the price to $450? 
  • Lifetime Value: What is the lifetime value of an AMEX card holder over the next three years
  • Profitability: A running shoe manufacturer sells shoes for $100 a pair. Their costs include $10 in materials and $5 in labor. They have $1 million dollars in monthly operating costs. If they sell 30,000 pairs a month, what is the monthly profit?

The world is getting more analytical and numbers-oriented. If you're interviewing at one of the highly sought after positions below, you'll need to master these Interview Math questions:

▪ Management Consulting: McKinsey, Bain, Boston Consulting Group, Deloitte
▪ General Management: Capital One, Taser
▪ Marketing: General Mills, Google, Hershey
▪ Software Engineering: Goldman Sachs, Microsoft
▪ Finance: American Airlines, Best Buy, JetBlue

Check out Interview Math for helpful frameworks to tackle these questions, including 50 sample answers and questions.
