+- Based on the candidate's actual skills from their resume
+- Testing theoretical knowledge, architecture decisions, best practices
+- Asking about real-world scenarios and problem-solving approaches
+- NO coding/programming challenges - only conceptual questions

+Question Distribution:
+- 10 Technical questions (in-depth concepts about their listed skills like {skills})
+- 3 Soft Skills questions (teamwork, leadership, conflict resolution)
+- 2 Communication questions (explaining technical concepts, stakeholder management)
+
+Example good technical questions:
+- "Explain the difference between SQL and NoSQL databases and when you would choose each"
+- "What are the SOLID principles and how have you applied them?"
+- "Describe microservices architecture and its trade-offs vs monolithic"
+- "How does garbage collection work in [language]?"
