QA (Quality Assurance) Software Tester Cover Letter Example

Dear Hiring Manager,

As a self-proclaimed tech enthusiast and problem solver, I was thrilled to come across the QA Software Tester opportunity at Microsoft, a company that has always been at the forefront of innovation and technology. From the moment I first laid my hands on a Windows 95 computer, I knew I wanted to be a part of the team that continues to revolutionize the way we interact with technology.

In my previous role at Resume Worded, I was responsible for designing and implementing a QA testing process that reduced software bugs by 55% within six months. I accomplished this by combining manual testing with automated regression testing, ensuring that we caught defects before they made their way to the end-user. Furthermore, I spearheaded a cross-functional initiative to improve communication between QA testers and developers, which led to a 25% decrease in turnaround time on bug fixes.

I am confident that my experience in QA testing and my passion for improving software quality will make me a valuable addition to the Microsoft team. I am particularly excited about the opportunity to work on groundbreaking projects like Azure and HoloLens, which are redefining the way we think about cloud computing and mixed reality.

Thank you for considering my application. I am eager to learn more about the role and discuss how my skills can contribute to Microsoft's ongoing success.
