About the Apache Spark for Data Engineers test

In today’s era of big data, businesses need powerful tools to process and transform it, and Apache Spark is one of the most powerful tools available today for big data operations. Since its release in 2009, its use has exponentially ramped up among companies that work with some of the largest datasets.

Though one of Spark’s key advantages is its ease of use, it takes an experienced data engineer to make the best use of all of its features. When you hire data engineers already well-versed in Apache Spark, your data projects will be completed more quickly, allowing your business to focus on implementing the solutions that the data implies.

This Apache Spark for Data Engineers test evaluates candidates’ abilities to apply their understanding of Apache Spark fundamentals, use Apache Spark for data transformation and processing, use Spark Core, and use Spark Streaming/Graph X.

This screening test will help you identify data engineers and other professionals who have strong experience with the Spark framework. Candidates who do well on this test will be able to efficiently problem-solve and execute on common Apache Spark scenarios they are likely to encounter on the job.

VP of engineering, mid-market (51-1000 FTE)

Any tool can have functions—bells and whistles. Not every tool comes armed with staff passionate about making the user experience positive.

The TestGorilla team only offers useful insights to user challenges, they engage in conversation.

For instance, I recently asked a question about a Python test I intended to implement. Instead of receiving “oh, that test would work perfectly for your solution,” or, “at this time we’re thinking about implementing a solution that may or may not…” I received a direct and straightforward answer with additional thoughts to help shape the solution.

I hope that TestGorilla realizes the value proposition in their work is not only the platform but the type of support that’s provided.

For a bit of context—I am a diversity recruiter trying to create a platform that removes bias from the hiring process and encourages the discovery of new and unseen talent.

FAQs

An assessment is the total package of tests and custom questions that you put together to evaluate your candidates. Each individual test within an assessment is designed to test something specific, such as a job skill or language. An assessment can consist of up to 5 tests and 20 custom questions. You can have candidates respond to your custom questions in several ways, such as with a personalized video.

A video question is a specific type of custom question you can add to your assessment. Video questions let you create a question and have your candidates use their webcam to record a video response. This is an excellent way to see how a candidate would conduct themselves in a live interview, and is especially useful for sales and hospitality roles. Some good examples of things to ask for video questions would be "Why do you want to work for our company?" or "Try to sell me an item you have on your desk right now."

Besides video questions, you can also add the following types of custom questions: multiple-choice, coding, file upload, and essay. Multiple-choice lets your candidates choose from a list of answers that you provide, coding lets you create a coding problem for them to solve, file upload allows your candidates to upload a file that you request (such as a resume or portfolio), and essay allows an open-ended text response to your question. You can learn more about different custom question types here.
