I caught their attention when they came to my campus for an on-site career fair. Their phone interview wasn't too difficult either; there weren't any coding questions.

However, the more annoying part of their interview process came a little afterward. Some of the few things that bothered me the most was that they wanted my high school GPA and my ACT/SAT score, which wouldn't bother me so much if I wasn't in college already.

Their online assessment wasn't any better either. The math portion of the online assessment made me feel even more insulted; it seemed to be annoying algebra or word questions people would ask middle schoolers.

However, once those were over, the on-site interview was fantastic. They made me feel extremely welcome, and I can definitely tell it's one of the best places to work at.

Suppose you have a set of patients in the United States who are at risk of heart attacks.

Each person has a device on them that returns a set of 15 boolean values, each value corresponding to a risk factor for heart attacks. (You don't need to understand the hardware implementation of this device; just understand that it works.)

Describe a database that will help doctors understand when a patient is most likely at risk of a heart attack.
