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.
They asked me to walk through one of my recent end-to-end data science projects and explain how I approached the problem, what techniques I used and the impact it created.

Given a table that each day shows who was active in the system and a table that tracks ongoing user status, write a procedure that will take each day's active table and pass it into the ongoing daily tracking table. Possible states are: * user stayed (yesterday yes, today yes) * user churned (yesterday yes, today no) * user revived (yesterday no, today yes) * user new (yesterday null, today yes) Note: you'll want to spot and account for the undefined state.
