How to Prepare for a Spark Hire Interview
Aside from the standard tech interview questions, Spark Hire interview questions
are often trickier than you might think. This article will help you prepare for a Spark Hire interview, including tricks and techniques to answer trick questions. In this article, you'll discover the Top 50 Apache Spark interview questions, as well as tips on how to prepare for one-way video interviews. You'll also learn how to prepare for a one-way interview before going on to the real thing.
Top 50 Apache Spark interview questions
When you prepare for an Apache Spark interview, you should be ready to answer the following questions:
What is the purpose of Apache Spark? How is it used to process data? How do you apply it in your work? Apache Spark is a framework for analyzing and processing large amounts of data. It uses the GraphX
component to organize and analyze structured data, similar to batch processing. GraphX
enables programmers to reason about structured data at scale. It uses MLlib, a library for scalable Machine Learning. The library supports common learning algorithms and dimensional reduction.
Why should you learn Apache Spark? Unlike Hadoop, Spark is able to integrate with other Big Data tools, including MapReduce
and Hive. It can access any data source on a Hadoop cluster and can run on the same computer. However, unlike Hadoop, Spark doesn't have its own storage system and relies on HDFS and other file systems. Another key difference between Spark and Hadoop is its in-memory capabilities. Spark can become a bottleneck when dealing with Big data, however. The application uses a distributed architecture, which can be a challenge for some companies. While Hadoop was the first open source Big Data framework, it wasn't very user-friendly. Additionally, it uses Java to build applications. This made it apt for batch processing, but not for stream processing.
Common questions asked during a one-way video interview
During a one-way video interview, you will be filmed answering common interview questions. One-way interviews typically consist of three to ten questions. The good thing is that you will only have a limited amount of time to think about each question. You can prepare for one-way interviews before the real thing. You can even practice for them by watching some videos of candidates in the same industry.
Before you begin, make sure you have a strong internet connection. In addition, ask anyone who will be watching the interview not to use the internet for at least 10 minutes. Turn off any other applications that might distract your interviewee from being attentive. Once you're ready to begin, make sure you're seated still and focused on the camera. Practicing these tips will make your one-way video interview a success.
Techniques for answering trick questions in a Spark Hire interview
When preparing for a Spark Hire interview, candidates should think about three examples of professional skills they possess that they could use to differentiate themselves from other applicants. While it is tempting to categorize these as "flaws," the question's purpose is to test a candidate's honesty and humility. This trick question can be found in countless interview playbooks. Listed below are three examples of the best ways to answer it.
Preparation for a Spark Hire interview
Whether you're applying for an entry-level job or are interested in pursuing a more advanced career, preparing for a Spark Hire interview is important. In addition to preparing for the interview itself, you'll need to prepare answers to common questions. A good way to prepare is to use a one-way interview simulation tool, such as Loom or your mobile phone. Record your responses and review them later. This tool will provide useful tips and examples of what you should say during your Spark Hire interview, which will increase your chances of getting hired for the job.
Make sure you're in a well-lit, quiet space. Avoid background noise, such as a television, radio, or stereo. Also, make sure you have a well-lit, simple background. Test the lighting before you sit down with the interviewer. Try placing a lamp slightly above the camera's position and the other behind you. This will ensure that your eyes stay in focus. Lastly, try to stay off your phone while you're on the phone.
