Deciding on a Tech Stack for a Scala Developer
When hiring a Scala Developer, it is essential to consider the tech stack that complements Scala's strengths. Scala is often used in conjunction with frameworks like Akka for building concurrent applications, Play for web applications, and Apache Spark for big data processing. Ensure the candidate is familiar with these frameworks and tools, as well as the integration of Scala with Java, given Scala's interoperability with Java libraries.
Assessing skills of a Scala Developer
Assessing a Scala Developer involves evaluating their proficiency in Scala programming, understanding of functional programming concepts, and experience with Scala frameworks like Akka and Play. Look for candidates with a strong grasp of concurrent programming and their ability to write clean, efficient Scala code. Practical assessments might include coding challenges or developing a small application using Scala to demonstrate their skills.
