【B：障害対応・トラブルシューティング経験 / Handling Production Issues】
▼ WPF・バックエンド系
- “Once, we faced a major performance issue in a WPF application where UI freezing was affecting end-users. I optimized the data binding process and implemented asynchronous loading using async/await to fix the issue.”
▼ フロントエンド系
- “We encountered a critical rendering bug in the React production build that affected our main dashboard. I quickly isolated the issue using browser dev tools and pushed a hotfix within two hours.”
▼ フルスタック系
- “I handled a situation where a backend API update broke the front-end integration. I coordinated with both teams, implemented a temporary middleware patch, and then worked on a permanent fix.”
▼ QA系
- “During a production release, I detected a critical regression that would have caused data loss. I immediately escalated it to the development team, and we delayed the release until it was fixed.”
【C：プロジェクト成功体験 / Success Stories】
▼ WPF・バックエンド系
- “One project I’m proud of was developing a real-time monitoring dashboard using WPF and SignalR. This reduced issue detection time by 40% for our operations team.”
▼ フロントエンド系
- “I led the implementation of a new component-based architecture in our Angular project, which significantly improved code reusability and reduced future development time.”
▼ フルスタック系
- “I designed and built a REST API backend and integrated it with a React front-end for a new client portal, delivering the MVP within just 3 months.”
▼ QA系
- “I introduced automated UI tests using Selenium and integrated them into our CI/CD pipeline, which reduced manual regression testing time by 50%.”
【D：技術的課題への対応力 / Learning & Adaptability】
- “Although I didn’t have prior experience with [新技術名] when I joined my last project, I quickly picked it up by following online courses and completing small side projects.”
- “I enjoy stepping out of my comfort zone. Recently, I learned Docker and Kubernetes to help with deployment automation.”
