This post was last edited by Anonymous on 2025-10-02 15:11. I'm working on a cybersecurity startup. The question was straightforward: find the median of an array. The following content requires a score higher than 180. You can already view it. The resume was the main focus, and I spent about 10 minutes on it. 1. Direct sorting; 2. Using heap sort; Quick select was mentioned in the middle, but I forgot the code. I explained it briefly at the end, but didn't write it. The follow-up question was, what if the input is a stream? I gave a vague answer, but didn't write any code.
