Data Science Test

Description

The advent of computer technology has been a transformative event in human history. We’ve come a long way from the days when computers were housed in bulky, unattractive cabinets where only a small percentage of users could access them. Today’s data-driven companies use enormous quantities of information that they acquire through software applications to build their own internal decision-support systems. While it’s often claimed that the organization with the most data wins, the one with the best-managed data derives the most valuable insights and emerges victorious. And you’ll need a data scientist for that.

The test assesses candidates’ understanding of basic data science and programming concepts and their theoretical grasp of statistics, machine learning, neural networks, and deep learning.

Candidates who pass this test can handle data competently and utilize big datasets to explore circumstances and draw conclusions.
