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 utility to find duplicate files on a given file system. The utility should traverse a directory, compute a hash for each file, and identify duplicates based on these hashes. Discuss the algorithmic complexity, potential optimizations, and trade-offs between CPU and RAM usage. What is the theoretical best performance we can achieve?

Tell me about a time you had a conflict with a colleague. What was the nature of the conflict, and how did you approach resolving it? What was the outcome, and what did you learn from the experience? For example, perhaps you disagreed on the best approach to a technical problem, or maybe there was a misunderstanding about responsibilities. How did you communicate your perspective, and how did you listen to theirs? What steps did you take to find a mutually agreeable solution? Did you involve a mediator or supervisor, or were you able to resolve it yourselves? What were the key takeaways from that situation, and how have you applied those lessons to future collaborations? It is important to show that you can handle conflict well.
