#1 Identifying job-fit candidates based on job roles
You can design customized big data tests for any given job role. Using this capability, you can choose questions from different skill types, including functional, technical, and soft skills. For example, with our customized big data online test, you can assess candidates' understanding of Hive, Map Reduce, Greenplum, Data Analysis, Flume, Oozie, and more to hire the best individuals for the job.
#2 Skill-gap analysis of your employees
iMocha allows you to measure employees' skill competency through big data training assessments. It determines the current skill level and identifies the areas for growth. Using this feature, you can measure employees' progress from their existing knowledge base to gained knowledge. For example, you can use our big data training tests to identify an engineer's knowledge about Pyspark, Zookeeper, Data Interpretation, and other skills and perform a skill gap analysis.
We provide various types of big data tests to help you evaluate candidates' specific skills. These questions are created by Subject Matter Experts (SMEs) based on their knowledge and expertise. For example, only big data specialists will develop questions about Pig, Sqoop, Hadoop, Hortonworks, or Kafka based on easy, medium, and hard difficulty levels.
You can - choose which questions to include in the big data online test or ask us to create personalized assessments according to your requirements.
