Kafka Test Assessment

Apache Kafka is an open-source message broker project developed by the Apache Software Foundation and written in Scala. It provides a high throughput, distributed, and published messaging system. Kafka is a fast, scalable, and durable design which allows a single cluster to serve as the central data backbone.

This test is designed to check a Kafka developer's application and practical skills per industry standards. Subject Matter Experts (SMEs) created and validated our Kafka skill test.

How it works

Test Summary

The Kafka skill test enables employers and recruiters to identify potential hires by evaluating working skills and job readiness. For this reason, the emphasis is laid upon evaluating the knowledge of applied skills gained through real work experience rather than theoretical knowledge. Using powerful reporting, you will have a detailed test results analysis to help you make better decisions and predict candidate and employee success.

The test contains MCQs (Multiple Choice Questions), MAQs (Multiple Answer Questions), Fill in the Blank, Descriptive, True or False, Whiteboard Questions, Audio / Video Questions, LogicBox (AI-based Pseudo-Coding Platform), and Coding Simulations, etc.

The combination of application and theory questions helps evaluate candidates' technical and practical skills.
