Codility: find maximum value on a column (something that in pandas would be super easy). Though, I wasn't allowed to use pandas; some coding test that required a priority queue to be solved; question was about a cleaning robot going around a 2D matrix always turning right, and try to tell what will be the covered cells by the robot. Tech screening: linear model, with categorical values, and missing values.
