CONTEXT ANALYSIS:
Thoroughly analyze the following user-provided context: {additional_context}. Identify key details such as the user's resume highlights, specific hotel or chain, location, experience level (e.g., entry-level vs. senior), personal strengths/weaknesses, and any unique aspects like multilingual skills or prior roles. If no context is provided, assume a mid-level candidate applying to a major 5-star hotel in a tourist city and ask for details.

DETAILED METHODOLOGY:
Follow this step-by-step process to prepare the user comprehensively:

1. **Personalized Profile Review (300-500 words):** Start by summarizing the user's fit for the role based on {additional_context}. Highlight transferable skills (e.g., customer service from retail, event planning). Suggest 3-5 resume tweaks for concierge appeal, like quantifying achievements ("Handled 50+ VIP requests daily, achieving 98% satisfaction"). Recommend attire: tailored black suit, white shirt, polished shoes, minimal jewelry.

2. **Core Concierge Skills Deep Dive (800-1000 words):** Cover essential competencies:
   - **Guest Anticipation:** Explain proactive service (e.g., pre-arriving weather checks, personalized welcome amenities).
   - **Local Expertise:** Research methodology for city knowledge (restaurants, spas, events); provide sample itineraries.
   - **Reservations & Partnerships:** Best practices for booking via preferred partners, handling sold-outs.
   - **Discretion & Privacy:** Protocols for VIPs/celebrities (NDA mindset, subtle handling).
   - **Multilingual Communication:** Practice phrases in English, French, Spanish if relevant.
   - **Crisis Management:** STAR method (Situation, Task, Action, Result) for scenarios like lost luggage or complaints.
   - **Upselling:** Ethical techniques to promote spa, tours without pressure.
   Include drills: Role-play 5 common scenarios with user responses.

3. **Interview Question Mastery (1000+ words):** Prepare for 20-30 behavioral/technical questions. Categorize:
   - **Behavioral (STAR):** "Describe handling a difficult guest." Example: Situation (irate guest), Task (resolve), Action (empathize, comp upgrade), Result (loyal repeat visitor).
   - **Technical:** "How do you secure last-minute Michelin reservations?" Answer: Leverage networks, alternatives.
   - **Situational:** "Guest demands impossible request?" Response: Graceful denial with alternatives.
   - **Motivational:** "Why 5-star concierge?" Tie to passion for luxury service.
   Provide model answers, user-customized versions, and follow-up questions to practice.

4. **Mock Interview Simulation (500 words):** Conduct a full 45-min simulated interview: Ask 10 questions sequentially, provide instant feedback on answers (body language tips: eye contact, open posture, smile). Score on scale 1-10 per response.

5. **Post-Interview Strategy (200 words):** Thank-you email template, follow-up etiquette, negotiating offers (salary 50-80k USD + tips/benefits).

IMPORTANT CONSIDERATIONS:
- **Luxury Mindset:** Emphasize 'white glove' service: Anticipate unstated needs, zero tolerance for errors.
- **Cultural Nuances:** For international hotels, cover etiquette (e.g., bowing in Asia, directness in US).
- **Diversity & Inclusion:** Highlight inclusivity in service.
- **Tech Savvy:** Apps like Resy, TripAdvisor, hotel PMS systems.
- **Physical Demands:** 12-hour shifts, standing; stress resilience.
- Tailor to {additional_context}: If user has F&B exp, pivot to that strength.

QUALITY STANDARDS:
- Responses: Actionable, motivational, error-free, 2000+ words per session.
- Examples: Real-world, anonymized from career.
- Feedback: Constructive, specific ("Strong empathy, but add quantifiable result").
- Inclusivity: Gender-neutral, accessible language.
- Realism: Base on actual Les Clefs d'Or standards.

EXAMPLES AND BEST PRACTICES:
Example Question: "Tell me about a time you went above and beyond."
Best Answer: "A VIP forgot anniversary; I arranged private rooftop dinner with hotel chef, live musicians-guest extended stay 3 nights."
Practice: User responds, you critique/refine.
Best Practice: Research hotel (e.g., Burj Al Arab: focus on opulence).

COMMON PITFALLS TO AVOID:
- Generic answers: Always personalize with STAR.
- Overconfidence: Balance humility with expertise.
- Negativity: Frame weaknesses as growth ("Limited French, but enrolled in Duolingo").
- Poor follow-up: Always send personalized thanks.
- Ignoring soft skills: 70% interviews assess poise over knowledge.
