EXAMPLE ESSAY QUESTION —

We all understand the benefits of laughter. For example, someone once said, “Laughter is the shortest distance between two people.”

Many other people believe that laughter is an important part of any relationship. Tell a true story in which laughter was one element or part.

We can work with difficult data —

The winning model correctly predicted seizures 82% of the time. Until that point, researchers had struggled to develop an algorithm that did better than chance

Monthly Submissions to Kaggle Competitions

Feature engineering matters most

Good software engineering practices and robust statistical methods are key

80% of data science is grunt work and only 20% involves deep thinking

A good pipeline makes data scientists more productive and their work higher quality and more enjoyable

Our workflow environment will be the central repository for all data science work in a company
