Back to School: Exercises to Level Up in FP
summary
Weekly, mentor-led programming exercises (one small timeboxed problem announced Monday with a collective correction Friday) were used to teach functional programming on a Spark/Scala banking codebase. The approach emphasizes short real problems, code reviews and feedback loops rather than long courses, and produced measurable gains: more functional idioms in production, team demand for exercises, and reuse for onboarding new hires.
