coding interview

This mock assessment test is for those who are in search of a job, applying for a job for the first time, or trying to find a challenging role outside where one currently works. 

The purpose of a mock coding assessment is to provide people (students/working professionals/or practically anyone) with an opportunity to practice coding interview skills in an environment similar to an actual coding interview. A mock assessment is a great opportunity to become familiar with coding assessment questions and formats.

HackerEarth brings to you these mock interviews with real-company questions, a simulated coding assessment interview environment, and a platform used by Fortune 500 companies. 

In the process, people can gain confidence by acquiring knowledge about their strengths and shortcomings. After all, no one is perfect enough to execute everything flawlessly when out of practice. 

Our Data Science mock interview will help you prepare for your next interview.
