📝 About
Technical assessment platforms used by employers to screen candidates via timed online tests. Key characteristics include:
- Mixed question formats: multiple-choice, fill-in-the-blank, coding tasks, and design scenarios.
- Language & framework coverage: supports Ruby, Rails, React, Angular, AWS, SQL, DevOps and more.
- Time-boxed: each test typically runs 30–60 minutes, depending on role complexity. Each tests (1/12) allocated 2-8 mins depending on complexity.
- Auto-grading + manual review: coding tasks are auto-checked against test cases; system-design answers may be manually reviewed.
- Real-world scenarios: questions often mimic production challenges rather than classic white-board puzzles.
📋 Software Architect Test Structure
On these type of platforms, a Software Architect assessment usually combines:
- System & API Design
- Coding & Code Review
- Architecture Patterns
- DevOps & Cloud
- Database & Performance
- Front-end Integration
Below is a breakdown with sample questions you can practice.
🔧 1. System & API Design
1.1 Design a RESTful API
- Prompt: Sketch endpoints (URL, HTTP verbs, request/response JSON) for a multi-tenant blogging platform.
- What’s tested: URI naming, resource nesting, versioning, authentication.
1.2 High-Level Architecture Diagram
- Prompt: Draw (in ASCII or pseudo-UML) a scalable order-processing system that integrates with payment gateways, queues, and microservices.
- What’s tested: service decomposition, message brokering, fault tolerance.
❓Questions

💻 2. Coding & Code Review
2.1 Ruby/Rails Coding Task
- Prompt: Implement a Rails model method that finds all users with more than N orders in the last M days, using ActiveRecord.
- What’s tested: query efficiency, scopes, avoiding N+1 problems.

2.2 Code Quality Review
- Prompt: Given a snippet of JavaScript/TypeScript front-end code, identify anti-patterns and refactor for maintainability.
- What’s tested: SOLID principles, readability, modularity.

🏗️ 3. Architecture Patterns
3.1 Design Patterns Identification
- Prompt: Which design pattern is best suited for plugging in new payment methods at runtime? Explain with a short UML sketch.
- What’s tested: Strategy, Factory, Dependency Injection.
Premium: https://railsdrop.com/software-architect-guide-design-patterns-identification/ - Understanding Design Patterns & Anti-Patterns in Ruby: https://railsdrop.com/2025/07/03/software-architect-guide-design-patterns-anti-patterns-in-ruby/
3.2 Event-Driven vs Request-Driven
- Prompt: Compare when to use event-driven microservices versus synchronous HTTP-based services, citing trade-offs.
- What’s tested: consistency, latency, complexity.
Premium: https://railsdrop.com/software-architect-guide-event-driven-vs-request-driven/
☁️ 4. DevOps & Cloud (AWS)
4.1 AWS CI/CD Pipeline
- Prompt: Propose an AWS-based CI/CD pipeline for a Rails application that must deploy to multiple regions. Include services and sequence.
- What’s tested: CodeCommit/CodeBuild/CodePipeline (or GitHub Actions), CloudFormation/Terraform, cross-region replication.
https://railsdrop.com/software-architect-guide-aws-ci-cd-pipeline-rails-app-deployment-multi-region/
4.2 Server Scaling Strategy
- Prompt: How would you manage session state in an auto-scaling group of Ruby on Rails servers?
- What’s tested: Sticky sessions vs Redis/Memcached as external store.
Premium: https://railsdrop.com/software-architect-guide-server-scaling-strategy/
🗄️ 5. Database & Performance (SQL)
5.1 Query Optimization
- Prompt: Given a slow SQL query with multiple joins, rewrite it using indexes and/or denormalization to improve performance.
- What’s tested: EXPLAIN output, index selection, covering indexes.
Premium: https://railsdrop.com/software-architect-guide-query-optimization-slow-sql-with-joins/
5.2 Schema Design
- Prompt: Design a relational schema for a multi-language product catalog, ensuring easy localization and high read throughput.
- What’s tested: normalization, partitioning/sharding strategies.
🌐 6. Front-end Integration
6.1 React Component Design
- Prompt: Build a stateless React component that fetches and paginates API data. Outline props, state hooks, and error handling.
- What’s tested: Hooks, prop-drilling vs context, error boundaries.
6.2 Angular vs React Trade-offs
- Prompt: Compare how you’d structure a large-scale dashboard in Angular vs React. Focus on modules, lazy loading, and state management.
- What’s tested: NgModules, Redux/MobX/NgRx, bundle splitting.
6.3 React Native Considerations
- Prompt: You don’t have React Native experience—explain how you’d architect code-sharing between web (React) and mobile (React Native).
- What’s tested: Monorepo setups (e.g. Yarn Workspaces), shared business logic, native module stubs.
💡Preparation Tips
- Hands-on practice: Spin up mini-projects (e.g. Rails API with React front-end, deployed on AWS).
- Mock interviews: Time yourself on similar Platform problems—aim for clarity and brevity.
- Review fundamentals: Brush up on design patterns, AWS core services, SQL indexing strategies, and front-end state management.
- Document trade-offs: Always justify architecture decisions with pros/cons.
Good luck, Architect to Greatness! 🚀
