Apache Flume Online Assessment test

The Flume Test assists employers in evaluating the job skills of a Flume Developer before an interview. Flume is one of the available services which is efficiently used for collecting and moving large amounts of log data. It is designed in such a way that it copies streaming data from various web servers. Using Flume, we can store it in any centralized store, such as HDFS and HBase. The Apache Flume online test is specially designed to check the application and practical skills of a Flume Developer per industry standards.

The Flume pre-hiring test enables employers and recruiters to identify potential hires by evaluating working skills and job readiness. For this reason, an emphasis is laid upon evaluating the knowledge of applied skills gained through real work experience rather than theoretical knowledge.
