QA Developer Hiring Guide

Quality assurance or quality control is a set of business processes that ensure the quality and reliability of software. It protects customers' needs and improves customer satisfaction scores. Quality control processes help detect problems that can cause enormous financial and reputational damage. It also reduces UI/UX problems and redundancy in the analyzed system.

You can also create automated QA workflows to perform repetitive use cases. This reduces manual errors and reduces costs. Furthermore, it allows you to carry out more quality checks in the same period of time.

Quality control is a collaborative process. The team's input and feedback helps in monitoring processes and delivering quality applications. You can use quality control tools to create schedules, develop SOPs, and work on process controls. Using quality control tools also reduces product redesign and recall issues.

You can use languages ​​like Java, Python, and C# to check code quality and testing. QA professionals use certain QA tools to ensure that a particular test is correct or not. They can be checklists, control charts and peer reviews. Techniques such as cost-benefit analysis, benchmarking and quality management are used to measure the effectiveness of a quality control strategy.

Frameworks are also an important part of the quality control process. QA engineers often use frameworks to improve and optimize their testing processes. Some common testing frameworks for this purpose include Selenium, Waitr, Capybara, and Windmill.

Quality control in today's market

Companies are now adopting new technologies such as AI and machine learning into their quality control workflows. 80% of companies surveyed say that AI is one of the most important parts of their testing process, while 68% say they have already adopted the necessary automation tools for their quality control process.

Tech giants including Microsoft, Facebook and Google have well-established infrastructure and quality assurance teams. They use product processing and monitoring to ensure maximum accuracy when providing products and services used by millions of consumers.

Problems Companies Face When Hiring a Quality Control Engineer

One of the main problems companies face when hiring QA engineers is that sometimes even experienced QA engineers lack experience with test automation tools, which are rapidly being implemented in organizations around the world. These tools save time and can run tests without manual intervention. This time can be used to create better test cases.

Quality control professionals must also be able to perform a risk analysis. Features such as structural testing and probability should be used to recognize faults and errors in the system. Unfortunately, many engineers are unable to leverage available information to create a mitigation plan for known risks.

How to Choose the Perfect Quality Control Engineer?

To select a perfect QA engineer, you must check their proficiency in QA methodologies and frameworks. They must also be efficient in programming languages ​​such as Java, Python and C++.

The candidate must be an expert in bug/error recognition and must have a good knowledge of software testing frameworks and tools. They must also be able to perform regression testing and identify bottlenecks in the project. Additionally, a quality control engineer must also have communication, collaboration, documentation, and reporting skills.

Interview Questions

What are agile tests?

Agile testing means testing your software using agile methodology. In this approach, you don't wait for the project to complete to check the code quality. Instead, you focus on coding and testing simultaneously.

This procedure is sometimes called test-driven development. This process saves time and improves code quality.

How do you explain black box testing?

Black box testing is also called specification-based testing. It refers to a testing process in which the functionality of a software is tested without examining its code or internal structure. It can have different components like functional testing, integration testing, regression testing, and user acceptance testing.

Define incremental integration testing?

Incremental integration testing means continually testing a project whenever new functionality is added to the core library. It helps deliver better quality code by ensuring that the final product is rigorously checked every time you make a new change to the system.

In this type of testing, engineers add modules using stubs/drivers to identify defects. The module is then subjected to automated testing at regular intervals. You can use different approaches for incremental testing, such as mixed/sandwich approach, top-down approach, and bottom-up approach.

What are DMAIC and DMADV in quality control?

DMAIC is a data-driven process used to improve project quality. This process includes 5 phases – Define, Measure, Analyze, Improve and Control. This process helps define project requirements, measure project results, and improve errors. This is part of the Six Sigma initiative.

DMADV stands for Define, Measure, Analyze, Design and Verify. Refers to a data-driven quality program that helps identify critical characteristics of a product. You can also find out the risk associated with a project.

What do you understand about configuration management?

Configuration management is a process that regulates and reports any changes that occur in the system over time. It is a way of managing changes that occur over time to ensure they do not negatively affect system efficiency and performance.
