What to look for in a Scala developer

Scala is a general-purpose programming language that provides support for functional programming and strong static type system. The design for Scala began in 2001 by Martin Odersky. The key advantage of Scala is that its functional, object-oriented, and can work with all programming styles.

Experienced Scala developers should have extensive knowledge of the pattern-matching system, and Scala’s uniques case classes. In addition to this, a proficient Scala developer should understand the main object-oriented patterns of Scala; Singleton, Value object patterns, and lazy initialization.
