The combination of Apache Spark and Python technology creates PySpark. Python is a general-purpose, high-level programming language, whereas Apache Spark is an open-source cluster-computing platform focused on speed, ease of use, and streaming analytics. PySpark is Python's library to use Spark. By using PySpark, one can easily integrate and further work with RDD in python programming language too. Numerous features make PySpark a fantastic framework for working with massive datasets and data exploration techniques.
This PySpark skill test helps employers in many ways, including hiring a job-fit candidate within a short period, taking unbiased employee performance appraisal decisions, and reducing hassle in mass recruitment. You can reduce hiring time by up to 40% with the PySpark programming test.
You can create customized skill assessments for any required job role. Using this feature, you can choose questions from different skill types, including functional, technical, and soft skills. For example, with our customized Pyspark test, you can evaluate candidates’ knowledge of Big Data Formation, Programming language (Python/Scala/Java), Spark SQL, MLlib, and GraphX Library and assess the best individuals for the job.
iMocha allows you to measure employees' skill competency through SAP training assessments. It determines the existing skill level and identifies the areas for growth. It also measures the knowledge and impact of the training and traces individual employees’ progress. For example, you can use our Pyspark training assessments to identify a consultant’s knowledge about Datasets, Data Transformation, Machine Learning and other skills and perform a skill gap analysis.
