Scala Coding Interview Practice
Scala blends object-oriented and functional programming on the JVM, and is widely used in big data engineering (Apache Spark), financial systems, and companies like Twitter, LinkedIn, and Stripe. Interviews in Scala often reward functional thinking — immutable data structures, pattern matching, and higher-order functions.
Why Scala for Interviews?
Scala's type system is one of the most expressive on the JVM. Case classes, sealed traits, and pattern matching make data modeling elegant. The collections library (Map, Set, List, Vector, Queue) with functional methods (map, flatMap, foldLeft, groupBy) makes algorithm code both concise and readable.

Scala Interview Tip
Lean into immutable collections: List, Map, Set from the scala.collection.immutable package. Use case classes for tree nodes and linked list nodes. Pattern matching with match/case is cleaner than if-else chains. Know how to use foldLeft and scanLeft for DP-style problems without mutable state.
