If you want to hire a Big Data Engineer, having well-prepared Big Data Engineer Interview Questions is essential for finding a suitable applicant.

What is a Big Data Engineer?

A Big Data Engineer is a specialist responsible for managing the storage, processing, and analysis of large and complex data sets. They work to develop and maintain systems that can store, manage, analyze, and visualize vast quantities of data. Big Data Engineers are highly skilled in using the most advanced solutions, such as Apache Hadoop and Apache Spark, to process data of all types and sizes. They are also experts in creating detailed reports from complex data sets, creating dashboards to visualize that information, and working with the latest Machine Learning technologies.

Typically, a Big Data Engineer has a Bachelor’s Degree in computer science, information technology, computer engineering, or a related field. They should have previous work experience in similar roles.

What does a Big Data Engineer do?

A Big Data Engineer is a specialist in leveraging and managing data systems to extract valuable insights from large amounts of information. They construct, maintain, and optimize the processes that are needed to take large datasets generated by multiple sources, store them securely in databases, and analyze them using sophisticated tools. The duties of a Big Data Engineer include designing, developing, and implementing big data solutions to store, process, analyze, and visualize large amounts of structured and unstructured data.

They must be familiar with relevant technologies such as Hadoop clusters, NoSQL databases (MongoDB or Cassandra), Spark Streaming/MLib algorithms, Kafka systems for message queues, etc. Other responsibilities might include creating real-time streaming applications utilizing Kafka streams API; developing APIs & microservices using Java/Scala/Python; integrating ML models into production systems in cloud environments; performance tuning for distributed systems & monitoring clusters for health checks; deploying applications using DevOps tools like Jenkins CI/CD pipelines, etc.
