Coding Implementation and Quality Questions
Assesses the ability to implement robust, readable, and maintainable code during interviews and in production. Topics include writing syntactically correct solutions, thorough handling of edge cases and invalid inputs, null checks and boundary conditions, clean naming and function design, design patterns and avoiding antipatterns, unit testability, debugging and tracing techniques, and adapting solutions in real time when interviewers introduce follow up constraints or optimization requests. Candidates should demonstrate both correctness and production orientation in their code.
