A Data Engineer Test is a pre-employment assessment tool for hiring managers and recruiters to screen and evaluate applicants and identify top job candidates for data engineering roles. This test evaluates a person's technical skills, understanding and familiarity with data modeling, database systems, warehousing, cloud technologies, and big data technologies.

Designed by subject matter experts, this 60-minute test includes 19 MCQs and 1 Coding to determine the eligibility of candidates for data engineering positions. By assessing a candidate's proficiency in data engineering tools and technologies, this test enables hiring managers to make objective hiring decisions and build a team of competent data experts with exceptional skills. 

Key profiles this Data Engineer Test is used for: 

• Data engineer jr.   
• Data engineer 
• Data engineer (using Python programming)

Overview 

Organizations need the expertise of data engineers to design, develop, and maintain the systems and infrastructure necessary for the effective processing and storage of a tremendous amount of data. Data engineers help ensure that databases and data pipelines are scalable, efficient, and reliable while optimizing data storage, retrieval and distribution procedures. Hiring data engineers is essential because it allows organizations to tap the full potential of their data by offering crucial technical expertise and infrastructure for data analysis while mitigating the risk of data-related hassles and errors. 

However, employers must use the Data Engineer Pre-employment Screening Test to ascertain the job suitability of candidates before hiring them. The test is crucial because it helps employers determine whether applicants have the technical expertise and knowledge necessary for the data engineer role. After all, hiring the right data engineer can be essential for the success of an organization's data-driven projects. 

The importance of the Data Engineer Assessment in the hiring process is that it helps evaluators identify the most deserving candidates. In addition, by evaluating a test-taker's skills and knowledge beforehand, employers can screen out applicants who lack the necessary skills or experience and select the right-fit talent for the next stage of the hiring process.  

This pre-employment test covers a range of topics, as listed below, to gauge the depth and breadth of a candidate's data engineer skills: 

• Hadoop - Hive: Questions based on Hadoop and Hive applications
