First round was a 30 minute interview with two of their data scientists. General introduction, project experience and reasons for certain decisions. Next stage was a take home task. Task was super niche and required a large amount of background research. I think the amount of work they expected is just evidence of the burnout culture that likely exists at the company. Spent the full week working on it and went above and beyond on parts, creating a .py script to run in a productionised environment too. Given this, they didnt respond for 2.5 weeks despite me chasing them up. Eventually contacted a DS directly who responded and HR provided feedback within a day. All in all, feedback was hugely unhelpful and respectfully disagreed with it. Main feedback was need for more EDA which when the data is artifically generated without any features names associated (X1,X2 etc.), makes little sense to me. I (stupidly) decided to prioritise the algorithm they were evaluating rather than go through the trivial steps of EDA and comparing multiple different out-the-box classifiers which feel like something you prioritise showing in more junior DS interviews. All in all, process took over 2 months which is a joke. Definitely appears that they forgot about me in the process.
