Data Flow Diagram
User Action API Call Response
─────────────────────────────────────────────────────────────────
1. Navigate to /candidates
└─→ Page component mounts
└─→ Fetch managers list (GET /api/managers)
└─→ Fetch positions list (GET /api/positions)
└─→ Fetch candidates (GET /api/candidates?status=NEW)
└─→ [API filters by role + applies RBAC]
└─→ Returns: { items, page, total, hasMore }
2. Click filter (e.g., status=HR_SCREENED)
└─→ FiltersBar updates URL → /candidates?status=HR_SCREENED
└─→ Page detects URL change
└─→ Fetches candidates with new params
└─→ [API applies new filters]
└─→ Table updates with results
3. Click candidate row
└─→ Router navigates to /candidates/[id]
└─→ Detail page loads candidate
└─→ Shows HR Screening, Manager Review, SMO Decision tabs
4. Next page button
└─→ Updates URL → /candidates?page=2
└─→ Page fetches next page
└─→ API skips 20, takes 20
└─→ Table shows items 21-40
RBAC Access Control Matrix
Role View Access Filter Access
────────────────────────────────────────────────────
HR All candidates All candidates

Manager Only assigned to me Own assigned only
(where hiringManagerId Cannot see others

SMO TO_SMO + decided Only TO_SMO
(APPROVED/REJECTED/KIV) status
Admin All candidates All candidates
(reads only) any filter
────────────────────────────────────────────────────
Enforcement: Server-side in GET /api/candidates
Protection: Manager cannot bypass via URL manipulation

Overdue Thresholds (Hardcoded)
Status Threshold Logic
────────────────────────────────────────────────────────
NEW > 2 days HR should screen
HR_SCREENED > 2 days Manager should assign
MANAGER_EVAL_PENDING > 3 days Manager should review
MANAGER_REVIEWED > 3 days SMO should decide
TO_SMO > 2 days SMO should finalize
APPROVED Never (completed)
REJECTED Never (completed)
KIV Never (completed)
COMPLETED Never (completed)
Note: W17 will implement SLA configuration table
to replace hardcoded values

Quick Reference: Saved Views by Role
HR Screener
- Needs HR Screening: status=NEW (candidates waiting for HR)
- Needs Manager Assignment: status=HR_SCREENED, manager=null (no manager yet)
- Active Pipeline: status=NEW|HR_SCREENED|MANAGER_EVAL_PENDING|MANAGER_REVIEWED|TO_SMO
- All: all candidates (HR can see all)
Manager
- My Queue: assigned to me, status=MANAGER_EVAL_PENDING (waiting for my review)
- Waiting for SMO: assigned to me, status=TO_SMO (waiting for SMO decision)
- My Reviewed: assigned to me, status=MANAGER_REVIEWED (I've reviewed)
- All Assigned: all candidates assigned to me
SMO (Senior Management Officer)
- Needs Decision: status=TO_SMO (waiting for my decision)
- Recent Decisions: status=APPROVED|REJECTED|KIV (decisions I've made)
Admin
- All Candidates: no filters (full access to all candidates)
URL Query Parameters Reference
Parameter Type Example Purpose
────────────────────────────────────────────────────────────────────
q string ?q=john Search name/code
status string ?status=NEW,HR_SCREENED Filter by status
applyingFor string ?applyingFor=Engineer Filter by position
hiringManagerId string ?hiringManagerId=123 Filter by manager
assignedToMe boolean ?assignedToMe=true Current user's candidates
createdFrom ISO date ?createdFrom=2024-01-01 Date range from
createdTo ISO date ?createdTo=2024-01-31 Date range to
overdue boolean ?overdue=true Show overdue only
page number ?page=2 Pagination
pageSize number ?pageSize=50 Items per page
sort string ?sort=updatedAt_desc Sort order
Example combined: /candidates?status=TO_SMO&overdue=true&page=1&pageSize=20
Integration Points
From W10 (SMO Decision)
- Uses Decision model for decision history
- Displays status=APPROVED/REJECTED/KIV after decision
- Links to SMO Decision tab when clicking candidate
From W9 (Other Features)
- Uses statusUpdatedAt field (already in Candidate model)
- Uses hiringManager relationship
- Uses CandidateStatus enum values
To W12 (Future - Candidate Detail)
- Candidate detail page already exists at /candidates/[id]
- Has tabs: HR Screening, Manager Review, SMO Decision
- W12 will add more sections
Performance Considerations
Query Type Performance Notes
──────────────────────────────────────────────────────
Search O(n) Full table scan, indexed on fullName
Status filter O(1) Indexed enum field
Manager filter O(1) Foreign key index
Date range O(log n) Indexed date field
Pagination O(1) Skip/take optimized
All combined O(n) Depends on result set
Optimization Tips:
• Add database indexes on: status, hiringManagerId, createdAt
• Limit page size to 100 max
• Consider elastic search for full-text search (future)
Error Handling
Scenario Handling
────────────────────────────────────────────────────
Network error Show toast + retry button
Invalid page number Fallback to page 1
No results Show empty state
RBAC violation 403 error (should not occur)
Database error Show generic error message
Invalid filter combo Silently ignore invalid filters
Unauthorized access Redirect to login
