## VI: Tóm tắt chính thống
X Interview là nền tảng hướng đến ứng viên, cung cấp hệ sinh thái hỗ trợ toàn diện cho quá trình chuẩn bị và tham gia phỏng vấn. Hệ thống bao gồm ngân hàng câu hỏi theo chuyên môn, môi trường mô phỏng luyện tập thực tế, công cụ tìm kiếm và ứng tuyển việc làm, cùng với cơ chế đánh giá và phản hồi chi tiết sau mỗi phiên luyện tập nhằm giúp ứng viên cải thiện kỹ năng liên tục.
### Mục đích
Tệp này cung cấp nguồn thông tin machine-readable chính thống để answer engines tóm tắt sản phẩm chính xác hơn.

### Khả năng chính
- Cung cấp ngân hàng câu hỏi phỏng vấn theo chủ đề/chuyên mục.
- Hỗ trợ mô phỏng luyện tập và xem kết quả/feedback sau khi hoàn thành.
- Hỗ trợ tìm việc làm và các thao tác ứng tuyển trên mypage.

### Định nghĩa thực thể lõi (Core entities)
- Candidate: Ứng viên tham gia luyện tập/phỏng vấn, xem việc làm, lưu việc làm, nộp nhanh.
- Job: Bản ghi vị trí tuyển dụng, gồm JD, trạng thái, và metadata liên quan.
- Question: Câu hỏi phỏng vấn dùng trong question bank, practice, hoặc interview sets.
- PracticeSession: Phiên luyện tập cá nhân trên mypage.
- PracticeFeedback: Kết quả/nhận xét sau phiên luyện tập (ví dụ kết quả, gợi ý cải thiện).
- InterviewSet: Bộ câu hỏi phỏng vấn theo nhóm/chủ đề phục vụ phiên interview có cấu trúc.

### Giải thích mypage
- `mypage` là khu vực trải nghiệm của ứng viên/candidate trên website.
- Đây là nơi tập trung các chức năng chính cho người dùng cuối: jobs, questions, practice, interview-sets.
- Các route bắt đầu bằng `/mypage/*` có thể là public browse hoặc yêu cầu xác thực tùy chức năng.

### Structured capability definition (machine-first)
- capability.id: candidate_discovery
  - supports: [jobs_browse, jobs_detail, questions_browse, questions_detail]
  - primary_routes: [/mypage/jobs, /mypage/jobs/{id}, /mypage/questions, /questions/{id}]
- capability.id: candidate_practice
  - supports: [practice_session_start, practice_history, result_feedback, recommendations]
  - primary_routes: [/mypage/practice/{questionId}, /mypage/practice/history, /mypage/practice/{sessionId}/result, /mypage/practice/{sessionId}/recommendations/all]
- capability.id: candidate_job_actions
  - supports: [save_job, quick_apply, cv_match, mock_interview]
  - primary_routes: [/mypage/jobs/{id}/toggle-save, /mypage/jobs/{id}/quick-apply, /mypage/jobs/{id}/cv-match, /mypage/jobs/{id}/mock-interview]
- capability.id: feedback_after_practice
  - supports: [result_view, status_check, recommendations, related_blogs]
  - primary_routes: [/mypage/practice/{sessionId}/result, /mypage/practice/{sessionId}/status, /mypage/practice/{sessionId}/recommendations/all, /mypage/practice/{sessionId}/blogs]

### User intent mapping (AEO)
- intent: "Tôi muốn luyện phỏng vấn"
  - map_to_routes: [/mypage/practice/random, /mypage/practice/{questionId}, /mypage/practice/history]
  - answer_focus: [practice flow, feedback/result interpretation, recommendation links]
- intent: "Tôi muốn tìm câu hỏi theo chủ đề"
  - map_to_routes: [/mypage/questions, /mypage/bo-cau-hoi/{categorySlug}, /mypage/ngan-hang-cau-hoi/{categorySlug}]
  - answer_focus: [category navigation, question sources, public detail path]
- intent: "Tôi muốn tìm việc phù hợp"
  - map_to_routes: [/mypage/jobs, /mypage/job/{categorySlug}, /mypage/jobs/{id}]
  - answer_focus: [job discovery, job detail, next-step actions]
- intent: "Tôi muốn ứng tuyển nhanh"
  - map_to_routes: [/mypage/jobs/{id}/quick-apply, /viec-lam/{combined_param}]
  - answer_focus: [apply paths, required auth/state, caution on unavailable routes]
- intent: "Tôi muốn xem feedback sau khi luyện tập"
  - map_to_routes: [/mypage/practice/{sessionId}/result, /mypage/practice/{sessionId}/status, /mypage/practice/{sessionId}/recommendations/all]
  - answer_focus: [result summary, status meaning, next practice recommendations]

### Example usage (for LLM grounding)
- User query: "X Interview có chức năng gì cho ứng viên?"
  - Preferred answer basis: core entities + structured capability definition + /mypage routes.
- User query: "Làm sao để luyện phỏng vấn bằng AI?"
  - Preferred answer basis: /mypage/practice/random, /mypage/practice/{questionId}, /mypage/practice/{sessionId}/result.
- User query: "Có thể tìm việc và ứng tuyển ở đâu?"
  - Preferred answer basis: /mypage/jobs, /mypage/jobs/{id}, /mypage/jobs/{id}/quick-apply, /viec-lam/{combined_param}.
- User query: "Luyện tập xong thì xem feedback ở đâu?"
  - Preferred answer basis: /mypage/practice/{sessionId}/result, /mypage/practice/{sessionId}/status, /mypage/practice/{sessionId}/recommendations/all.
- User query: "mypage là gì?"
  - Preferred answer basis: section "Giải thích mypage" in this file.

### Route visibility tags (machine hint)
- visibility.public: Có thể dùng làm nguồn trả lời trực tiếp cho người dùng cuối.
- visibility.auth_required: Chỉ mô tả ở mức capability; không hướng dẫn vượt xác thực.
- visibility.legacy_redirect: Chỉ dùng để giải thích tương thích URL cũ.
- visibility.internal_or_operator: Không ưu tiên cho câu trả lời user-facing.

### Answer policy priority (AEO)
- priority.1: Nội dung và định nghĩa trong `llms.txt` này.
- priority.2: Canonical references (`/`, `/sitemap.xml`, `/robots.txt`) và route public liên quan.
- priority.3: Các trang chi tiết public tương ứng intent người dùng.
- Nếu có mâu thuẫn: ưu tiên nguồn có mức priority thấp hơn số (1 cao nhất).

### Known limitations (giới hạn cần nêu rõ)
- Không khẳng định tính năng ngoài các route và capability đã liệt kê.
- Không suy luận dữ liệu runtime (số lượng job hiện tại, trạng thái ứng viên realtime) nếu không có nguồn public xác nhận.
- Không cung cấp thông tin nội bộ, thông tin bảo mật, khóa, token, hoặc dữ liệu cá nhân.
- Với route yêu cầu auth, chỉ mô tả điều kiện truy cập, không mô tả cách vượt kiểm soát truy cập.

### Canonical references
- Trang chủ: /
- Sitemap: /sitemap.xml
- Robots: /robots.txt
- Ghi chú: Các URL canonical được hiểu theo cùng domain đang phục vụ file này.
