The following questions are representative of what you can expect during the Kairos hiring process. These questions have been compiled from real candidate experiences and are designed to help you understand the core patterns and technical themes evaluated by the hiring team.

Test Automation & Javascript

These questions assess your hands-on coding ability, your understanding of Javascript fundamentals, and your expertise with Cypress.

• How do you handle asynchronous operations in Javascript, and how does Cypress manage commands asynchronously?
• Explain the difference between Page Object Model (POM) and App Actions in Cypress. Which one do you prefer and why?

To succeed in the Kairos interview process, you must approach your preparation with a clear strategy. The hiring team looks for candidates who possess a blend of strong technical capabilities and a collaborative mindset.

Role-Related Knowledge – You must demonstrate a deep understanding of modern test automation. This means being highly proficient in Javascript and knowing the ins and outs of Cypress, including its architecture, limitations, and best practices. Interviewers will evaluate your ability to write clean, maintainable, and efficient test code.

Problem-Solving Ability – You will be assessed on how you analyze complex applications and break them down into testable scenarios. You should be prepared to explain your thought process when designing test cases, identifying edge cases, and troubleshooting failing tests in a continuous integration environment.

Collaboration & Communication – Because Kairos operates as a consultancy, your ability to collaborate with developers, product managers, and clients is critical. You must show that you can advocate for quality constructively, explain technical bugs clearly, and work seamlessly within an agile team structure.

Adaptability – Projects at Kairos can change rapidly depending on client needs. You need to demonstrate that you are comfortable with ambiguity, can quickly learn new domains, and are capable of adjusting your testing strategies to suit different project requirements.

The interview process for the QA Engineer position at Kairos is structured to evaluate both your technical execution and your alignment with the team's collaborative culture. The process typically begins with an initial touchpoint and progresses through practical technical evaluations before reaching a final decision.

The journey starts with a recruiter call, where you will discuss your background, your experience with test automation, and your alignment with the role's requirements. The recruiter will also explain the vacancy details and the compensation package. Following a successful initial screen, you will be invited to complete a technical exam or coding challenge, which is a pivotal stage of the evaluation.

After the technical exam, successful candidates are typically invited to a technical interview to discuss their exam submission, dive deeper into automation architecture, and answer behavioral questions. The overall process is designed to be rigorous but fair, focusing heavily on your practical ability to write code and design test strategies.

The timeline above outlines the standard progression from your initial contact to the final offer stage. You should use this visual guide to pace your preparation, ensuring you allocate sufficient time to practice hands-on coding before the technical exam. Keep in mind that while the technical stages are structured, the overall timeline can vary slightly depending on team availability and location.

To excel in the Kairos interview, you must understand the specific areas where the hiring team will focus their evaluation. Expect a deep dive into your technical execution and your strategic approach to quality assurance.

Test Automation with Cypress and Javascript

This is the core technical evaluation area for the QA Engineer role. Interviewers want to see that you do not just use Cypress as a record-and-playback tool, but that you understand its underlying architecture and can write robust, programmatic automation scripts.

Be ready to go over:

• Cypress Architecture – How Cypress runs directly inside the browser and how this differs from Selenium-based frameworks.
• Asynchronous Execution – Managing promises, chaining commands, and understanding how Cypress handles execution queues.
• Test Structure & Maintainability – Structuring test suites using design patterns like Page Object Model or custom commands to minimize code duplication.
• Advanced concepts (less common) – Integrating Cypress with CI/CD pipelines (e.g., GitHub Actions, Jenkins), configuring parallel test execution, and setting up visual regression testing.

Example scenarios:

• "You are tasked with automating a multi-step checkout flow that involves dynamic third-party payment iFrames. How would you handle this in Cypress?"
• "Explain how you would write a Cypress test to verify that an API payload matches the UI state after a form submission."

Test Strategy and QA Methodology

While automation is highly valued, Kairos also needs engineers who understand the "why" behind their testing. You must demonstrate that you can design logical, risk-based test plans that maximize coverage while minimizing execution time.

Be ready to go over:

• Test Case Design – Applying equivalence partitioning and boundary value analysis to complex business logic.
• Defect Management – Writing clear, actionable bug reports and managing the defect lifecycle within tools like Jira.
• Test Optimization – Identifying flaky tests, debugging test failures efficiently, and optimizing test execution speed.
• Advanced concepts (less common) – Implementing contract testing, performance testing basics, or security testing practices within the QA pipeline.

Example scenarios:

• "A new feature is being deployed that impacts the core database schema. How would you structure your regression testing suite to minimize risk?"
• "How do you identify the root cause of a flaky test that passes locally but fails consistently in your CI/CD environment?"

As a QA Engineer at Kairos, your day-to-day work will be dynamic and highly integrated with the development cycle. You will not work in a silo; instead, you will be an active participant in shaping the product from its initial requirements to its final deployment.

• Designing and Maintaining Automation Frameworks – You will write, refactor, and maintain automated test scripts using Javascript and Cypress, ensuring high test coverage for critical user journeys.
• Collaborating with Agile Teams – You will participate in daily standups, sprint planning, and retrospectives, working closely with developers to understand implementation details and define clear acceptance criteria.
• Executing Manual and Exploratory Testing – While automation is a priority, you will perform exploratory testing on new features to identify edge cases and usability issues that automated scripts might miss.
• Integrating Tests into CI/CD Pipelines – You will configure and maintain automated test runs within continuous integration pipelines, ensuring that feedback on build quality is delivered rapidly to the development team.
• Reporting and Tracking Defects – You will document defects with precise reproduction steps, logs, and screenshots, collaborating with developers to verify fixes and ensure successful deployments.

To be competitive for the QA Engineer position at Kairos, you should possess a strong technical background in web technologies and a proven track record in test automation.

• Must-have skills – Strong proficiency in Javascript (ES6+) and extensive hands-on experience with Cypress for web automation.
• Must-have skills – Solid understanding of QA methodologies, modern testing practices, and the software development lifecycle (SDLC).
• Must-have skills – Experience working in agile development environments and utilizing tools like Jira for task and defect tracking.
• Nice-to-have skills – Familiarity with CI/CD tools such as GitHub Actions, GitLab CI, or Jenkins.
• Nice-to-have skills – Experience with API testing tools (e.g., Postman, SuperTest) and performance testing tools (e.g., k6, JMeter).
• Nice-to-have skills – Knowledge of visual testing tools (e.g., Percy, Applitools) and cross-browser testing strategies.
