When Do You Need to Hire a QA Tester?

Identifying the right time to bring a QA tester on board can significantly impact your product's success. Here’s a breakdown of when to hire a QA professional throughout the software development lifecycle:

Stage 1: Minimum Viable Product

The MVP is the initial version of a product with just enough features to satisfy early adopters. At this stage, hiring a QA tester helps determine essential features and ensures the product meets initial quality standards.

QA involvement at this stage is crucial but limited, about 30%.

Stage 2: First Release

Once the MVP has undergone initial testing, it's time to focus on essential features to minimize risks and costs. A QA tester’s role at this stage includes creating comprehensive documentation of the testing process.
QA involvement increases significantly to 80%.

Stage 3: Growth Phase

As your product gains traction, new features are introduced. A QA engineer becomes indispensable at this stage to continually test new features through regression, smoke, and sanity testing. QA involvement is at its 100%.

Stage 4: Stable Product

When your product has established a strong market presence, maintaining high standards is critical. QA engineers ensure flawless performance, design updates, and superior user experience. Their involvement remains high at 100%.

Stage 5: Expansion and Acquisition

During this phase, focusing on marketing and promotion is essential. QA engineers play a vital role in ensuring all updates and promotional features are bug-free and user-friendly. They help maintain control over development changes and iteration processes with involvement at 80%-100% depending on the project's characteristics.

What Are the Requirements/Skills for a QA Engineer?

1. Quality Mindset

You should not hire a task executor but rather a quality assurer - look for it. A good QA will not simply be following directives, it will act as the primary guardian of quality for your websites. QA should take ownership of project quality from A to Z to ensure that every aspect meets the highest quality standards.

4. Time Management

Software development requires a quick turnaround to increase the product’s time to market. The QA must assess the product thoroughly without holding up the timeline.

5. Detail-Oriented

It is impossible to guarantee the absence of bugs, but the QA has to be able to spot as many errors as possible. a QA needs the ability to see any minute defect that could derail the entire product and ultimately affect your business.

6. Proactive and Responsible

How to Evaluate the Skills of QA Engineers?

Evaluating a QA engineer's skills involves assessing both their technical and soft skills. Here are steps to effectively evaluate a QA engineer:

Technical Competence

Conduct a thorough technical assessment to determine a candidate’s proficiency in different testing methodologies, familiarity with testing tools, and ability to write and execute test cases. Key areas to cover include:

• Testing Tools Knowledge: Ensure familiarity with tools like Selenium, JIRA, QTP, LoadRunner, and others.

• Understanding Testing Methodologies: Verify their grasp of methodologies such as Agile, Scrum, Waterfall, etc.

• Test Case Design: Evaluate their ability to create comprehensive and effective test cases.

Soft Skills Evaluation

Soft skills are equally important in determining how well the QA engineer will integrate into your team and work environment. Evaluate key soft skills like:

• Communication Skills: Can they explain complex issues clearly and concisely?

• Team Collaboration: Are they capable of working effectively with others?

• Critical Thinking: Can they analyze problems and devise creative solutions?

• Adaptability: Are they flexible and able to adapt to changing requirements?

Practical Assessments

Providing real-world scenarios or test tasks can help evaluate a candidate’s problem-solving abilities and attention to detail. For example, give them a buggy piece of software and ask them to identify and report issues, or design a test plan for a new feature.

Interviewing a QA Tester

Asking the right questions during an interview can help gauge a candidate’s suitability. Here are some key questions to ask:

1. How do you approach work on a new project?

This question helps understand their strategy and methodology for tackling new tasks. Look for answers that emphasize documentation, test plans, and strategies.

2. How do you scope your testing amount?

This evaluates their understanding of testing principles. The ideal candidate should outline techniques and decision-making processes for testing strategies.

3. How do you set the criteria for QA testing?

This checks both hard and soft skills. Effective answers will mention teamwork, communication, proactivity, and critical thinking.

4. Which QA tools do you use and why?

This measures their knowledge of testing tools and whether their preferred tools align with your company’s needs.
