So the interview was pretty standard. First, I had to talk about my current experience, then they wanted me to go into detail about the system architecture I'm involved with. After that, there were some C++ specific questions and a coding challenge to implement the singleton pattern.

So, this was my very first interview, and it went for about an hour and a half. The role was in image processing. They started off by asking me to define what a histogram is and then some basic follow-up questions on that. Then, the second question was about writing pseudocode for a dictionary that uses a hash table. The third question was the LeetCode 'number of islands' problem, and they wanted a BFS solution. I didn't know BFS at the time, so I couldn't solve it. Lastly, they asked me about a project I had done. The questions themselves weren't super hard, but I didn't make it through because I didn't know BFS.
