Interview Process

The interview involved a coding question related to delivery cost. I practiced the problem at home multiple times but only managed to complete Part 2 during the actual interview. I briefly discussed my approach for Part 3. The interviewer asked several questions, such as how production code might differ from the code I wrote, and prompted me to describe different test cases. It was also emphasized that the input guarantees incremental end times, which I didn’t assume in my practice, making my solution more complex. The interviewer noted that I didn’t need to write such a complicated solution.
