About the test

The Apache Spark online test assesses knowledge of the Spark framework, how to use it to configure Spark clusters, and how to perform distributed processing of large data sets across clusters of computers.

The assessment includes work-sample tasks such as:

  • Using RDD Operations to create transformations and actions.
  • Configuring and deploying Spark Multi-Node Clusters.
  • Monitoring and tuning performance.

A good Spark developer or administrator should be familiar with Spark infrastructure, its configuration, and know how to use transformations and execute actions on data sets.

What others say

Decorative quote

Simple, straight-forward technical testing

TestDome is simple, provides a reasonable (though not extensive) battery of tests to choose from, and doesn't take the candidate an inordinate amount of time. It also simulates working pressure with the time limits.
