Let's talk about strings. Suppose you're given two strings, text and pattern. Your task is to implement a function that efficiently determines if the pattern is a subsequence of the text. A subsequence is a sequence that can be derived from another sequence by deleting some or no elements without changing the order of the remaining elements. For example, ace is a subsequence of abcde, but aec is not. Your function should return true if the pattern is a subsequence of the text, and false otherwise. Example 1: text = abcde pattern = ace Output: true Example 2: text = abcde pattern = aec Output: false Example 3: text = abcde pattern = Output: true (An empty string is always a subsequence) Example 4: text = pattern = abc Output: false (A non-empty string cannot be a subsequence of an empty string) Consider edge cases such as empty strings and differing lengths. Discuss the time and space complexity of your solution. Aim for an optimal solution.

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 you disagreed with a manager. What was the situation, and how did you handle it? What was the outcome, and what did you learn from the experience? For example, perhaps you had a disagreement about project priorities, a technical approach, or a team management style. It could be a situation where you felt strongly about a different course of action and had to navigate the disagreement professionally. Describe the specific steps you took to communicate your perspective, understand your manager's viewpoint, and reach a resolution. What factors did you consider in deciding how to approach the situation, and what alternative approaches did you consider? How did you ensure that the disagreement didn't negatively impact your working relationship or the overall team dynamic? What would you do differently in a similar situation in the future?
