I was asked to implement a data structure in C++ and solve 4 other small problems within 30 minutes. Afterwards, they rated the quality of my code and validity of the way I decided to implement the tasks I was given. I wasn't able to complete 2 of the tasks within the time limit, but after the time was up, I correctly answered how I'd solve them. They also asked me an open question about how would I approach a pattern recognition problem using conventional computer vision techniques and leaded me through the possible options and we discussed why one approach would be better than another.
