You are helping me build the following AI agent workflow.

## Goal
WhatsApp Recruitment Automation: Automates WhatsApp recruitment inquiries with an interactive menu for pricing, applications, and tracking.

## Specification
- What it does: You instantly handle recruitment inquiries on WhatsApp through an interactive menu that lets candidates check pricing, submit applications, and track their status. The system automatically saves your data in Google Sheets while escalating complex questions to your team so you can focus on hiring.
- Trigger: Triggered by an event (Event · on WhatsApp message)
- Autonomy: Fully hands-off
- Expected setup effort: about an afternoon
- Tools/services involved:
  - n8n: Automation engine
  - WhatsApp Business API: Messaging and interactive UX
  - Google Sheets: CRM and logs
  - Code: Custom logic and routing

## Known pitfalls, handle each one explicitly in your implementation
1. WhatsApp has strict template approval rules so you must pre-approve message templates for outbound replies outside of the 24-hour window.
2. Session state can drift if users switch devices quickly, so store unique session IDs in Google Sheets to maintain context accurately.
3. Data privacy regulations require explicit consent before storing candidate info, add a mandatory opt-in step before writing to the CRM sheet.

## Reference implementation
https://n8n.io/workflows/11604 (workflow template)
Fetch and inspect this before building. If it matches my stack, adapt it;
if not, rebuild the pattern with my tools.

## Process requirements
1. Before building: ask me which of the listed tools I actually use and
   what my platform is (n8n / Make / code / other). Do not assume.
2. Adapt the pattern to my answers; do not force the reference stack.
3. Address every pitfall above; tell me how you handled each.
4. Provide a test plan I can run before letting this touch real data.
5. Ask before any step that sends messages, modifies data, or spends money.
