How it works

The Database Management Assessment starts with fundamental database concepts and moves on to advanced queries and troubleshooting. The goal is to assess the candidate's ability to handle real-world data management challenges. In a 20-question format, this might look like:

  • Basic Level questions may ask candidates to write simple SQL queries or define key terms like primary key and foreign key.
  • Intermediate Level questions could involve joining tables, creating indexes, or setting up basic data security protocols.
  • Advanced Level questions might require complex query optimization, designing a relational schema, or implementing backup and recovery strategies.

The test is timed, allowing employers to see how efficiently candidates can perform tasks under time constraints.
