I had two interviews in one day. The first one was about team management, and the second one was coding. The coding interview was somehow easy. I was asked to write a small function like the tail utility in Unix/Linux. However, the issue was that I wasn't sure about what parameters read and seek functions take in C++. So, I wrote half a program. It was my mistake; during preparation, I didn't focus on files/streams. I thought questions would be focused on algorithms. I will give it another try very soon.

Implement a function like the tail utility in Unix/Linux.
