 ## Overview
 
-QuadPay is a payment gateway that lets consumers split purchases into 4 interest free installments, every two weeks. The first 25% is taken when the purchase is made, and the remaining 3 installments of 25% are automatically taken every 14 days. We help customers manage their cash-flow while helping merchants increase conversion rates and average order values.

 ## Background
 
-One of the cornerstones of QuadPay's culture is openness and transparency. When reviewing our existing interview structure, we found that pair-programming challenges rarely replicated what our employees actually do in their day-to-day work. For example, when was the last time you coded without google, or when the requirements weren't clearly defined? To tackle that, we've decided to publish our pair programming interview and share it directly with candidates beforehand.

Some areas that you'll work on include fraud prevention, building real-time credit-decisioning models and, most importantly, shipping products that are secure, frictionless, and deliver a high-quality consumer experience.
