Playwright Interview Questions: Core Topics You Must Master (With IPFLY Insights)

Interviewers evaluating Playwright skills often focus on practical, real-world scenarios—especially how you handle common challenges like geo-restrictions, IP bans, and stable test execution across regions. Below are the top Playwright interview questions, detailed answers, and how leveraging IPFLY can make your responses stand out, while also boosting your on-the-job performance and career top rankings.

1. Interview Question: How Do You Configure a Proxy in Playwright for Cross-Region Automation Testing?

This is one of the most common Playwright interview questions, as cross-region testing is a staple in global product development. To answer effectively, you need to explain both Playwright’s native proxy configuration methods and how to ensure reliability—something that IPFLY excels at.

First, outline Playwright’s basic proxy setup: You can configure proxies via the `launchOptions` in Playwright, specifying HTTP, HTTPS, or SOCKS proxies using the `proxy` object. For example, setting the `server` parameter to the proxy IP and port, and adding authentication if required. However, the critical distinction that impresses interviewers is explaining how to avoid common pitfalls like IP bans, slow connections, and inconsistent test results—issues that generic proxies fail to solve, but IPFLY addresses seamlessly.

IPFLY offers a massive pool of 90 million+ high-purity proxies spanning 190+ countries and regions, which is far more comprehensive than the limited coverage of generic proxies. When configuring IPFLY with Playwright, you can easily switch between static or dynamic residential proxies (or data center proxies) based on your testing needs—ensuring that your automation scripts mimic real user traffic from any target region. For instance, if you’re testing a e-commerce platform’s regional pricing, IPFLY lets you assign a unique residential IP from each target country to Playwright, avoiding detection by anti-bot systems and ensuring accurate test results. This level of detail in your answer not only shows technical proficiency but also demonstrates your understanding of production-grade workflows—key for landing top roles and advancing to career top rankings.

2. Interview Question: How Do You Handle IP Bans or Rate Limits When Running Playwright Scraping or Testing at Scale?

Interviewers ask this question to assess your problem-solving skills for large-scale automation—an essential requirement for senior roles. IP bans and rate limits are major roadblocks when running Playwright scripts across hundreds of URLs or test cases, and generic proxies often exacerbate the issue with shared, low-quality IPs that get blacklisted quickly. Here’s where IPFLY’s advantages shine, and integrating this into your answer will set you apart.

The key to avoiding IP bans with Playwright is using high-anonymity, non-shared proxies—and IPFLY delivers exactly that. Unlike generic proxies that reuse IPs across thousands of users (leading to rapid blacklisting), IPFLY’s residential proxies are sourced from real end-user devices and ISPs, and its data center proxies are exclusive to each user. When integrated with Playwright, IPFLY’s dynamic IP rotation feature automatically switches proxies at predefined intervals (or per request) for large-scale scraping or testing, ensuring that no single IP is flagged for excessive requests. Additionally, IPFLY’s 99.9% uptime guarantee means your Playwright scripts run continuously without interruptions from proxy downtime—a common pain point with free or low-cost alternatives.

For example, if you’re tasked with testing a website’s load time across 50 regions, IPFLY lets you configure Playwright to use a dedicated IP from each region, with built-in failover to backup IPs if one connection drops. This not only prevents IP bans but also ensures consistent, reliable test data—critical for making data-driven decisions. Explaining this workflow in your interview shows that you can scale Playwright automation effectively, which is a key competency for senior positions and career top rankings.

3. Interview Question: How Does Proxy Selection Impact Playwright Test Accuracy, and How Do You Choose the Right Proxy?

This question evaluates your ability to connect proxy selection to business outcomes—an important skill for roles that require delivering accurate, actionable test results. Test accuracy depends heavily on proxy quality: if your proxy is slow, unstable, or flagged, your Playwright scripts may return false negatives (e.g., reporting a broken feature that works for real users) or incorrect regional behavior. IPFLY’s proxy types are tailored to solve this, and explaining this will showcase your strategic thinking.

When choosing a proxy for Playwright, you need to align the proxy type with your use case—and IPFLY offers three options to cover every scenario:

• Static Residential Proxies (IPFLY): Ideal for long-running Playwright tests (e.g., overnight regression suites) that require a consistent IP identity. IPFLY’s static residential proxies are fixed, non-reused, and recognized as legitimate by target websites, ensuring that your tests reflect real user experiences without interruptions. This is far more reliable than generic static proxies, which often suffer from poor connectivity.
• Dynamic Residential Proxies (IPFLY): Perfect for cross-region compatibility testing or scraping, where you need to mimic user traffic from multiple locations. IPFLY’s dynamic proxies rotate automatically, and its multi-region coverage lets you test Playwright scripts in 190+ countries—something generic proxies (with <50 country options) can’t match.
• Data Center Proxies (IPFLY): Best for high-speed Playwright tests (e.g., load testing) that require low latency. IPFLY’s data center proxies offer millisecond-level response times, outperforming generic data center proxies that are often overcrowded and slow.

By explaining how IPFLY’s proxy types align with specific Playwright use cases, you demonstrate that you don’t just “set up proxies”—you strategically select tools to ensure test accuracy. This level of expertise is what interviewers look for in top candidates, and it’s what will help you climb to career top rankings by delivering reliable, high-quality work.

4. Interview Question: Can You Explain How to Integrate Proxies with Playwright’s Browser Contexts for Isolated Testing?

This technical question tests your deep knowledge of Playwright’s architecture, as browser contexts allow for isolated testing sessions (each with its own cookies, local storage, and proxy settings). To answer effectively, you need to connect browser context configuration to proxy management—and IPFLY’s flexibility makes this integration seamless.

Playwright’s `browser.new_context()` method lets you assign a unique proxy to each context, which is critical for testing multiple user journeys simultaneously (e.g., testing a login flow from the US and EU at the same time). When integrating IPFLY, you can dynamically fetch proxy credentials from IPFLY’s API and inject them into each Playwright browser context—ensuring that each session uses a unique, high-quality IP. For example, you can write a helper function that pulls a US-based IP from IPFLY’s pool for one context and a German IP for another, all within the same Playwright script.

IPFLY’s API integration is straightforward, with detailed documentation that makes it easy to connect to Playwright—something that generic proxies often lack (many require manual proxy configuration, which is inefficient for isolated testing). Additionally, IPFLY’s 24/7 technical support ensures that if you run into integration issues (e.g., proxy authentication with Playwright’s context options), you can resolve them quickly—critical for meeting tight deadlines in production environments. Explaining this integration in your interview shows that you can build scalable, maintainable Playwright scripts, which is a key skill for advancing to senior roles and career top rankings.
