Meta Software Development Engineer interview questions

3 interviews, each with a software engineer asking me to implement functions in python. Like implement a convolutional layer. The questions were not difficult; there were some trick questions in terms of knowing you can find the median in O(n) with quick select, as opposed to O(n*log(n)) with sort and grab the middle element.

An hour of solving two technical questions that varied in difficulty from easy to medium on leet code The interviewer was very nice and he answered all my questions without judgment
