Technical Phone Screen - Automation Architecture & Design
What to Expect
A 50-60 minute technical interview conducted over video focusing on automation strategy and framework design. You'll likely be presented with a scenario (e.g., 'Design an automation framework for a mobile app with 50+ features') and asked to articulate your approach to test strategy, framework architecture, technology selection, and CI/CD integration. This is not a live coding round but rather a discussion-based assessment of your automation design thinking. You may be asked to sketch architecture ideas or discuss implementation approaches.
Tips & Advice
Approach this as a design conversation, not a technical deep-dive. Start by asking clarifying questions about the product, constraints (timeline, team size, budget), and success metrics. Use a structured framework: define what to test (test pyramid approach), select appropriate tools and technologies, design for maintainability and scalability, and integrate with CI/CD. Discuss trade-offs (e.g., E2E vs. API automation, Selenium vs. Playwright, monolithic vs. distributed test architecture). Mention specific tools you've used (Selenium, Cypress, Playwright, REST Assured, etc.) and your rationale for choosing them. Address non-functional requirements like test stability, execution speed, and reporting. For Staff level, emphasize strategic thinking—how you'd prioritize automation efforts, manage technical debt in test code, and scale the automation system as the product grows. Discuss how you'd mentor engineers on the approach and build a culture of quality.
Focus Topics

Technical Phone Screen - Automation Coding & Implementation
What to Expect
A 50-60 minute live coding round conducted in a shared coding environment (Google Doc or Codepen-like platform) where you'll implement automated tests or part of a test framework. You might be asked to write tests for a provided application or API, implement page object patterns, or design helper functions for a test framework. The focus is on code quality, test structure, maintainability, and your ability to write clean, readable automation code. You'll be evaluated on test design thinking (arrange-act-assert pattern), proper use of assertions, handling edge cases, and creating reusable components.
Tips & Advice
Ask clarifying questions before starting: What application am I testing? What's the scope (happy path, edge cases, error scenarios)? What tools/frameworks should I use? Start by sketching your approach and talking through your strategy before writing code. Use clear, readable code with meaningful variable names. Structure tests using Arrange-Act-Assert pattern. Use stable selectors (data-testid over CSS classes). Implement page object pattern or helper functions to reduce duplication. Write clear assertions that test user-visible behavior (text content, visibility) rather than implementation details (DOM structure, class names). Handle edge cases and error scenarios. For Staff level, show code organization thinking—how you'd structure this for a larger codebase with multiple engineers. Discuss test maintenance and what would happen if the UI changed. If you make a mistake, catch and fix it, explaining your thought process. Talk through your code as you write it—interviewers want to understand your reasoning, not just see the final result.
Focus Topics

This assesses your ability to think about automation at enterprise scale, make architectural trade-offs, and consider operational aspects like monitoring and debugging.
Tips & Advice
Treat this like a system design interview. Ask clarifying questions first: How many tests? Execution frequency? Geographic distribution? Budget constraints? What's the current pain point? Then break down the problem: test execution layer (how to distribute, parallelize), test data layer (provisioning, cleanup, isolation), reporting and analytics, flakiness detection and quarantine, resource management, and team organization. Discuss trade-offs: cloud vs. on-premise, shared vs. dedicated resources, centralized vs. decentralized test infrastructure. Address operational concerns like monitoring, alerting, and debugging failed tests. Propose specific technologies (e.g., Kubernetes for orchestration, database for test results, message queues for distribution). For Staff level, emphasize strategic thinking: how this scales, cost implications, how you'd roll this out in phases, how you'd get buy-in from teams. Discuss metrics to measure success and how you'd iterate based on feedback.

Interviewers evaluate how you handle ambiguity, work with other teams, influence without authority, and contribute to engineering culture.
Tips & Advice
Prepare 6-8 STAR stories that demonstrate staff-level qualities: mentoring engineers (specific examples of how you helped someone grow), driving adoption of new tools or processes (how you got teams to use your automation framework), collaborating across teams (resolving conflicts or aligning on shared infrastructure), handling ambiguity (defining vague problems), managing projects with significant complexity, and recovering from failures. For each story, clearly articulate the Situation (context), Task (what you needed to achieve), Action (what you specifically did, not the team), and Result (measurable outcome or impact). Emphasize your leadership role and influence, not just technical contributions. Be ready for follow-ups like 'What would you do differently?' or 'How did you measure success?' Give specific, quantifiable results when possible (mentored X engineers, reduced test time by Y%, achieved Z adoption rate). For Meta specifically, emphasize values like Move Fast (taking calculated risks), Impact (focusing on business outcomes), and Open Culture (sharing learnings, being transparent about failures). Mention specific experiences collaborating with other engineers or teams, and be honest about challenges and what you learned from them.

Onsite Interview - Technical Deep Dive - Advanced Automation Challenges
What to Expect
A 50-60 minute technical interview focused on solving a complex automation problem or handling advanced topics. You might be asked to discuss how you'd automate a particularly challenging scenario (e.g., testing real-time notifications, animations, complex user flows), handle performance testing at scale, manage test flakiness in CI/CD, or implement complex test frameworks. This round assesses deep technical expertise and your ability to think through nuanced problems that don't have simple answers.
Tips & Advice
This round tests your ability to handle ambiguous, real-world automation challenges. Ask clarifying questions to understand the problem deeply. Break down the problem into manageable pieces. For each challenge, discuss multiple approaches (trade-offs between stability, maintenance, and coverage), not just one solution. If discussing complex scenarios, be prepared to code or design on a whiteboard/doc. For Staff level, emphasize your experience handling edge cases and building elegant solutions. Discuss lessons learned from past projects. Be honest about trade-offs and limitations—no solution is perfect. If you encounter a problem you haven't solved before, show your thought process for how you'd approach it rather than faking knowledge. Mention specific tools and technologies you've used and why. For example, if asked about testing real-time features, you might discuss WebSocket testing, mocking strategies, or using native tools. Show depth of knowledge by discussing implementation details and potential pitfalls.
