Interview Questions to Hire Ruby on Rails Developers
Junior-level Ruby on Rails Developer Interview Questions
1. What are the advantages of Ruby on Rails?
Probe for understanding Rails’ convention-over-configuration philosophy, modular design (e.g., gems like Devise), and rapid prototyping capabilities. Look out for awareness of MVC architecture, ActiveRecord efficiency, and built-in testing (MiniTest/RSpec).
2. What are the disadvantages of Ruby on Rails?
Assess recognition of runtime speed limitations in CPU-heavy tasks, dependency on monolithic structure, and challenges in large-scale refactoring. Strong candidates will cite solutions like background job queues (Sidekiq) or service-oriented architectures to mitigate rigidity.
3. Mention a few features of Ruby.
Some of the features of the Ruby programming language are as follows:
- Dynamic and duck typing.
- Short and flexible syntax.
- Object-oriented programming.
- Metaprogramming.
- Garbage collection.
Expect explanations of dynamic typing’s flexibility (vs. static typing), metaprogramming’s role in DSLs (e.g., Rails routes), and object-oriented purity.
4. What is the application of the garbage collection feature in Ruby on Rails?
The garbage collection feature of Ruby on Rails ensures that the programmer does not need to manually relocate dereferenced memory. Garbage collection in RoR performs automatic memory management of data objects. Garbage collection eliminates coding errors such as wild pointers, double-free bugs, and memory leaks.
Validate understanding of memory management trade-offs: automatic dereferencing reduces leaks but can cause latency spikes. Discuss Ruby 3’s incremental GC improvements and tools like `memory_profiler` for optimization.
Senior-level Ruby on Rails Developer Interview Questions
1. How does Ruby on Rails trigger AJAX Operation?
AJAX allows web pages to refresh automatically when the server reflects changes. Ruby on Rails can trigger AJAX operation when:
- A change on the server level is initiated when trigger fires are launched with a button/link click.
- The web client calls upon the server while executing an XMLHttpRequest.
- The server sends an HTML fragment when triggered by a server-side action handler.
- Ruby on Rails generates client-side JavaScript, which receives and updates an HTML fragment within the page.
Require examples using `respond_to` blocks, Turbo Streams in Rails 8, or UJS (Unobtrusive JavaScript). Evaluate how they balance real-time updates with server load, including caching strategies and stimulus.js integration.
2. What are the uses of Ruby on Rails database migrations?
Ruby on Rails migration is used to change and update database schema over time. Ruby on Rails migration can rename a table, add a column, change or edit a column, drop a table, remove a column, and perform other similar operations. Using Rails migration makes your application database-independent, making it easier to switch platforms if required.
Test knowledge of reversible migrations, seed data management, and pitfalls (e.g., altering production tables). Senior answers should address zero-downtime deployment tactics, like using `change_column_null` safely.
3. What is CSRF? How does Ruby on Rails work against CSRF?
Cross-Site Request Forgery (CSRF) is a form of cyber attack used by hackers to damage or reveal confidential information. The protect_from_forgery command in Ruby on Rails Application Controller is helpful against CSRF attacks. This command generates CSRF tokens, verifying any post, put, or delete requests within your web application.
Beyond protect_from_forgery, explore token validation mechanics in Rails’ form helpers and API mode exceptions. Contrast with CORS configuration for external APIs and JWT authentication flows.
4. What does the Rails controller do in Ruby on Rails?
Ruby on Rails controller handles the interaction between the model, views, and users. As a logic center, the controller routes external requests and performs corresponding internal actions. The controller regulates helper modules to operate view templates without unnecessary lines of code. Rails controller also regulates live sessions to inform users about their interaction with the system.
Step 5: Onboarding Ruby on Rails Developers
To ensure a smooth onboarding process, hiring managers must follow certain protocols. Some of the major steps involved in onboarding new Ruby on Rails developers are as follows:
- Pre-arrival Preparation – Provision secure access to repositories (Git), project management tools (Jira), and monitoring systems (Datadog). Share architecture diagrams, API documentation, and a sandbox environment with seeded test data.
- Structured Integration – Pair with a senior developer for codebase orientation, emphasizing legacy systems and critical workflows. Schedule cross-functional meetings with DevOps (deployment pipelines) and Product (roadmap context).
- Initial Deliverables – Assign a well-scoped first task (e.g., debug a controller spec, add a feature flag) to build context without overwhelm. Conduct a 30/60/90-day review plan aligning with project milestones (e.g., “Own authentication module by Day 60”).
- Cultural Assimilation – Introduce team rituals (daily standups, retros) and Rails-specific practices (code reviews focused on security hotspots like SQL injection risks). Provide resources for ongoing learning (e.g., RailsConf recordings, internal wikis on custom gems). Also assign a teammate as their point of contact to clear doubts about their tasks, and help them understand the company culture.
