About the MySQL test
MySQL is a database-management tool that is widely used to store, manipulate, and access data, along with front-end tools. MySQL uses query language that results in more efficient work: Shorter lines of code accomplish big things.
This MySQL test is designed to evaluate candidates’ skills in using MySQL to create and manage tables. Tables are fundamental elements of many databases, and using crisp and clear code to create and manage tables is paramount to database usage.
This test will evaluate candidates’ abilities to manage and update the database itself, including operations with big data implications. Finally, this test will evaluate candidates’ use of complex queries, joins, procedures, and functions. These techniques are vital to the skill set of an intermediate MySQL practitioner.
This hiring test uses situational-judgment questions, which requires successful knowledge application gained from hands-on experience with MySQL. Candidates who do well on this MySQL test will help your business manage and use databases to your benefit, anticipating problems and finding the data you need, fast.
