This was essentially a technical interview with an engineer. I was very nervous throughout the entire process, but this unique experience of pair programming with a real engineer was amazing.

The interview question was not too difficult, but I saw online that they would prefer Object-Oriented Programming (OOP). I initially turned it into a more complicated one, but judging from the interviewee's reaction, I ultimately went with the most straightforward solution.

It took me more time than usual since I changed my plan halfway through. I achieved the correct output, but I suspect I failed anyway because I didn't include any comments or other supplementary elements.
