Estimated code review effort

🎯 4 (Complex) | ⏱️ ~75 minutes

  • Foreign key relationships and cascade behaviors: Verify that CASCADE and RESTRICT delete behaviors are appropriate for each relationship (e.g., Company cascade deletes to Employee/Position, Position cascade to Application)
  • Index strategy and uniqueness constraints: Review compound indexes and unique constraints (e.g., Application(positionId, candidateId), InterviewStep(interviewFlowId, orderIndex)) for correctness and performance implications
  • Migration reversibility and data integrity: Confirm migration can be safely reversed and that all constraints align with business logic
  • Recruitment workflow logic: Validate that the Application → Interview → InterviewStep flow correctly models the intended recruitment process with proper status tracking

Poem

🐰 Hop along through recruitment's gate,
Where candidates and positions correlate!
Interviews cascade like fields of clover,
A schema so grand, the workflow's takeover. 🎓

prompts/prompts-iniciales.md (1)

3-120: Spanish grammar and spelling improvements recommended.

The prompt document contains multiple grammar, spelling, and punctuation issues flagged by LanguageTool (e.g., line 3: "relizar" → "realizar", missing punctuation in several places, spacing inconsistencies). While these don't affect functionality, consider cleaning them up to improve documentation quality, especially if this serves as a reference for future exercises.

Examples of high-impact fixes:

  • Line 3: "relizar" → "realizar"
  • Line 3: "acontinuación" → "a continuación"
  • Line 13: "practicas" → "prácticas"
  • Add missing punctuation after step numbers and major sections (lines 107, 112, 113, etc.)
prompts/PLAN_EJERCICIO.md (1)

1-30: Well-structured implementation plan.

The document provides excellent phase-by-phase guidance, detailed model definitions, and practical testing procedures. Spanish grammar inconsistencies flagged by LanguageTool (capitalization, punctuation, spacing) are minor and don't impede understanding. Consider a light grammar pass if this plan will be shared beyond the team.

backend/prisma/schema.prisma (3)

96-127: Add explicit onDelete constraint to Position.interviewFlow FK.

Line 119 defines the relationship to InterviewFlow but doesn't explicitly specify onDelete. The migration (backend/prisma/migrations/20251114170733_add_lti_recruitment_entities/migration.sql, line 271) specifies ON DELETE RESTRICT, but this constraint is not reflected in the schema definition.

For clarity and maintainability, make the FK constraint explicit:

- interviewFlow InterviewFlow @relation(fields: [interviewFlowId], references: [id])
+ interviewFlow InterviewFlow @relation(fields: [interviewFlowId], references: [id], onDelete: Restrict)

This pattern should also be applied to other FKs with RESTRICT behavior (see comments below).


139-155: Add explicit onDelete constraint to InterviewStep relations.

Lines 149 and 150 define relationships but don't explicitly declare onDelete behavior. The migration specifies ON DELETE RESTRICT for interviewType (line 277) and implicit CASCADE for interviewFlow (line 274). Update the schema to match:

- interviewType InterviewType @relation(fields: [interviewTypeId], references: [id])
+ interviewType InterviewType @relation(fields: [interviewTypeId], references: [id], onDelete: Restrict)

Ensure interviewFlow relation already has onDelete: Cascade (line 148 should reflect this).


191-213: Add explicit onDelete constraints to Interview relations.

Lines 204–205 define FKs to InterviewStep and Employee without explicit onDelete behavior. The migration specifies ON DELETE RESTRICT for both (lines 289, 292). Add clarity to the schema:

- interviewStep InterviewStep @relation(fields: [interviewStepId], references: [id])
- employee      Employee      @relation(fields: [employeeId], references: [id])
+ interviewStep InterviewStep @relation(fields: [interviewStepId], references: [id], onDelete: Restrict)
+ employee      Employee      @relation(fields: [employeeId], references: [id], onDelete: Restrict)

This ensures schema-migration alignment and improves code readability.

4-4: Verify the non-standard database port choice.

Port 54321 deviates from PostgreSQL's default (5432). While this may be intentional for development isolation or Docker setup, ensure it's documented and aligns with your database service configuration (e.g., docker-compose.yml, local setup instructions).

backend/prisma/migrations/migration_lock.toml (1)

1-3: Minor formatting improvements.

The wording and trailing newline adjustments are appropriate and don't impact functionality.

backend/prisma/migrations/20251114170733_add_lti_recruitment_entities/migration.sql (1)

256-262: Reconsider foreign key constraints on Candidate relations.

Lines 256, 259, 262 use ON DELETE RESTRICT for Education, WorkExperience, and Resume → Candidate relationships. This means a Candidate record cannot be deleted if they have any education, work experience, or resume entries, even if deleting them would be desirable (e.g., GDPR data cleanup).

Verify whether:

  1. Blocking deletion is intentional (e.g., maintain historical records for audits), or
  2. CASCADE delete is appropriate (clean deletion of all candidate data including history)

If CASCADE is desired, update lines 256, 259, 262 to ON DELETE CASCADE.

17-33: Verify updatedAt field management in Candidate model.

The schema declares updatedAt DateTime @updatedAt (line 25), which tells Prisma to auto-manage this field on updates. However, the migration sets this field as NOT NULL without a DEFAULT value (migration.sql, line 10). Ensure that:

  1. On INSERT: Prisma client handles the initial value (Prisma should set it to CURRENT_TIMESTAMP)
  2. On UPDATE: Prisma client correctly updates this field

This should work correctly, but verify that any direct SQL inserts (outside Prisma client) include updatedAt to avoid NOT NULL violations.

🛠️ Refactor suggestion | 🟠 Major

Remove redundant indexes on already-unique columns.

The migration creates both unique and non-unique indexes on the same columns:

  • Lines 166-169: Candidate_email_key (unique) + Candidate_email_idx (non-unique)
  • Lines 172-175: Company_name_key (unique) + Company_name_idx (non-unique)
  • Lines 214-217: InterviewType_name_key (unique) + InterviewType_name_idx (non-unique)

A unique index already supports efficient lookups; the redundant non-unique index wastes storage and maintenance overhead. Remove the non-unique indexes on lines 169, 175, and 217.

Apply this diff:

- -- CreateIndex
- CREATE INDEX "Candidate_email_idx" ON "Candidate"("email");

Then repeat the removal for Company_name_idx (line 175) and InterviewType_name_idx (line 217).

around lines 165 to 175 (and similarly remove the duplicate at line ~217), the
migration creates both UNIQUE and non-unique indexes on the same columns; remove
the redundant non-unique CREATE INDEX statements. Delete the lines that create
"Candidate_email_idx" and "Company_name_idx" (and also remove
"InterviewType_name_idx" around line 217) so only the UNIQUE INDEX statements
remain, preserving ordering and any surrounding semicolons. Ensure no references
to the removed index names remain later in the file.

✅ Fortalezas

  • El modelo de datos está muy bien pensado y alineado con el dominio del Talent Tracking System (candidato → aplicación → entrevistas con flujos e hitos intermedios).
  • Has definido FKs y cascadas coherentes con lo que se espera en un sistema real, y además coinciden perfectamente con las relaciones de Prisma.
  • El uso de índices y claves únicas muestra que estás pensando en rendimiento y consistencia, no solo en que “funcione”.

🔧 Recomendaciones de mejora

  • Añade índices en las columnas candidateId de Education, WorkExperience y Resume para acelerar las consultas por candidato.
  • Evita índices redundantes donde ya tienes @unique + @@index sobre la misma columna (por ejemplo, email en Candidate, name en Company e InterviewType).
  • Refuerza la integridad de negocio con CHECK constraints (por ejemplo, rangos de salaryMin/salaryMax y score) y considera usar enums para los campos de estado/rol.

💬 Mensaje final

Muy buen trabajo: se nota que entiendes tanto el modelo de negocio como cómo llevarlo correctamente a SQL y Prisma. Ya estás en un nivel en el que las mejoras son finas y propias de alguien que piensa como DBA, no solo como dev. Sigue así, porque con pequeños ajustes (índices adicionales, enums, checks) tu esquema pasa de “muy bueno” a “nivel producción profesional”. 🚀
