Data Science & Analytics Test

Q: What is Data Science?

Data Science is the method of identifying hidden patterns from raw data. In order to do so, data scientists utilize a set of numerous tools, machine learning principles, and algorithms on structured and unstructured data. They also crack complex data problems to make insightful business decisions and predictions.

Q: How does data science analytics test help recruiters hire people?

The data used by data scientists are usually a collection of data gathered from various resources and compiled in a structured format to make an insightful decision. Hence, data science analytics is the collection of candidate data arranged logically to help recruiters with predictive power and more accurate insight into candidates' skills.

Q: Can I combine the test with other tests?

Yes, iMocha enables you to custom-create your assessments according to the requirements of your organization. For example, you can personalize your Data science analytics test by combining it with other related technical and non-technical skills. For example, you can combine Azure Data Factory, Big Data, Data Scientist with Python, Data Analytics Excel, communication test questions, etc.

Q: What are the certifications preferred for this role?
