Let's design a system to efficiently manage meeting room bookings for a large company. Consider the following: Scalability: The system should handle a large number of meeting rooms and employees. Concurrency: Multiple users should be able to book rooms simultaneously without conflicts. Features: Room availability search based on time, date, and number of attendees. Recurring meeting support. Integration with employee calendars (e.g., Google Calendar, Outlook). Conflict detection and resolution. Reporting and analytics (e.g., room utilization). Example: Imagine a company with 100 meeting rooms and 5000 employees. A user wants to book a room for a daily stand-up meeting with 10 attendees, recurring every weekday for the next month. How would your system handle this request, ensuring no double bookings and updating the user's calendar? Specifically, discuss the system architecture, data models, key algorithms, and potential bottlenecks. How would you address these bottlenecks to ensure the system remains responsive and reliable?

Tell me about a time when you had to sign a Non-Disclosure Agreement (NDA). Please provide specific details about the situation, including the parties involved, the nature of the confidential information, and the purpose of the NDA. Describe the scope of the agreement, including what was covered and any limitations. Explain your responsibilities under the NDA and how you ensured compliance with its terms. What steps did you take to protect the confidential information? Did you face any challenges in complying with the NDA, and if so, how did you overcome them? Share any lessons you learned from this experience regarding confidentiality and intellectual property protection. For example, imagine you were working on a sensitive project involving a new product or technology. You had to sign an NDA with a third-party vendor or partner to share certain confidential details. What were the key terms of the NDA, and how did you ensure that you and your team adhered to them? Or, describe a situation where you left a previous company and signed an NDA regarding trade secrets and customer information. How did you navigate your subsequent work to avoid any potential conflicts or violations of the NDA?
