      Top 5 Technical Interview Questions Asked Ruby Developer

      • Concept Tested: Understanding of Ruby’s function objects and how they handle arguments, return behavior, and their scope within the code.
      • Expected Answer: Candidates should explain that while both Proc and Lambda are types of Proc objects, they differ in their handling of return statements (Proc returns from the current context, Lambda returns control to the caller), and argument handling (Lambda checks the number of arguments, while Proc does not).
      • Concept Tested: Knowledge of concurrency and how to ensure that code running in multiple threads does not lead to race conditions or other thread safety issues.
      • Expected Answer: Candidates might discuss using thread-safe classes, mutexes to lock critical sections, or leveraging tools like ActiveSupport::Concurrency::SharedMutex in Rails. Additionally, they should understand when and how to use background jobs with libraries like Sidekiq to manage concurrency.
      • Concept Tested: Understanding of object-oriented programming in Ruby, particularly how self is used to refer to the current object or class in different contexts.
      • Expected Answer: Candidates should demonstrate knowledge that self represents the current object instance in instance methods, and the class itself in class methods. They might also explain how self is used to define singleton methods or access class-level variables.
      • Concept Tested: Understanding of memory management in Ruby and how the Ruby interpreter automatically reclaims memory that is no longer in use.
      • Expected Answer: The candidate should explain that Ruby uses a mark-and-sweep garbage collection algorithm, where it marks objects that are still in use and sweeps away those that are not. They might also mention improvements in recent Ruby versions, such as generational garbage collection.
      • Concept Tested: Practical skills in performance optimization, particularly related to ActiveRecord and database interactions.
      • Expected Answer: Candidates should discuss identifying slow queries using tools like rails console, EXPLAIN in SQL, or query logs. They should also explain strategies such as adding proper indexes, avoiding N+1 queries by using includes, eager loading associations, and leveraging caching mechanisms like Rails.cache or fragment caching.
