The Apache Cassandra Database Administration (Short) test is designed to evaluate the knowledge and skills of job candidates and employees necessary to support Apache Cassandra database configuration, maintenance, and operations, with a primary focus on practical administration competencies. The test measures skill across six key areas: CQL Syntax and Data Modeling; Replication, Consistency, and Read/Write Behavior; Nodetool and Cluster Operations; Compaction Strategies and SSTable Management; Backup, Restore, and Node Lifecycle Operations; and Cassandra Configuration and Security. Coverage includes topics such as data modeling concepts, cassandra.yaml configuration, replication strategies, consistency levels, nodetool commands, snitch configuration, backup and restore using snapshots, SSTable structure and the write path, gossip protocol, system table diagnostics, authentication and authorization, and multi-datacenter deployments. The test uses Multiple Choice, Multiple Correct Answer, and Essay Composition question types, with questions drawn from a large pool to help prevent cheating, and includes one or more time-limited questions to further deter cheating and improve predictive performance. Artificial intelligence is used in the scoring of one or more questions.

The specific attributes measured include:

Following completion, the test produces a Candidate Selection Report that includes an overall score and detailed scores for each attribute.

The Candidate Selection Report also provides expert interview questions that help you probe critical or low-scoring areas, along with a guide for noting your evaluation of the candidate's responses. Consistent use of an interview guide is an important part of gaining better candidate insights and making better hiring decisions.

Note that while the Apache Cassandra Database Administration (Short) assessment is a useful and efficient instrument for confirming a base level of skill or knowledge about this important topic, it is not intended to pinpoint the exact level of candidate or skill. We recommend that skills tests, like this one, be used in parallel with other measurements, such as cognitive ability, job fit, and behavioral history. Each different type of test provides a valuable piece of information you can use when evaluating potential job performance.
