QA Experience
Worked on project Betia English, HodooABC, HodooM
Role
QA Engineer
Industry
EdTech
Duration
1.5 years



Overview
I worked in Hodoolabs as a QA engineer, where I spent one and a half years ensuring the quality and usability of digital products.
I worked on ‘Betia English 1,2’, ‘Hodoo ABC’, ‘Hodoo M’ QA project.
This experience strengthened my attention to detail, analytical thinking, and deepened my understanding of user needs.
QA Process
Conduct test based on test case document
Before functional testing, I review the Product Requirements Document (PRD) to understand the intended features. Then, I write test cases that outline the steps needed to trigger each feature and document the entry depth of each UI element.
I conduct testing according to the user flow, ensuring that all functions work smoothly and naturally, and that the interface feels consistent.
If any issues arise, I collaborate with project managers, developers, and designers to make the necessary revisions.

Reflections
Focusing on user context - Hodoo ABC
After launching Hodoo ABC, an English learning app for children aged 6 to 10, we received multiple user inquiries reporting that children were having difficulty using the service. At this age, children often struggle with concentration, are unfamiliar with touchscreen gestures, and have smaller fingers that make precise tapping difficult. These real-world usage challenges were not fully captured during pre-launch testing.
To better understand user pain points, we reviewed actual gameplay videos submitted by parents. Based on our findings, we made the following key improvements:
1. Added clear tutorials for all game types
2. Introduced motion-based interactions with the game character
3. Enlarged UI elements and expanded touch target areas
Although we had conducted several rounds of internal testing, we failed to fully account for the real usage context of our target users. This experience taught me the importance of testing with actual users in realistic environments, not just relying on desk research or user interviews. By closely observing user behavior and iterating based on real feedback, we were able to significantly improve the user experience and accessibility of the service.
