Weird to say the least. Phone call followed by a data dump exam, as others have said here on Glassdoor. You have 24 hours to analyze their data to provide recommendations for the business. I didn't really believe others when they said it took them 10+ hrs to analyze, but sure enough, they provide you with what's basically a day's worth of work (if done well). It's not hard, but there isn't really any direction regarding how much analysis or the depth they're looking for. Recruiter was responsive but honestly it felt like the data analysis exercise is probably luck of the draw. If you're familiar with basic data analysis and excel functions you'll probably be okay. I imagine there's probably quite a bit of cheating when it comes to this exercise - people who've been told ahead of time about what to expect or given old data sets by friends or acquaintances - there's no way to prove people are dishonest, but I was curious after the fact and found that if you google around hard enough there are hints or old sample sets floating online with more information than is publicly available. Maybe DoorDash is trying to test your resourcefulness in this way? Altogether, the data set isn't very hard to analyze, they want some specific recommendations based on a month's worth of delivery data, but given the guidance of a few hours of analysis, and a time limit of 24 hours, who knows what they actually expect. I put in 2 hours of preliminary work and sent it back in. My guess is they probably want you to put more time into it than that. I hope the company does well but I don't think I would apply again for this position again. There were more quirks beyond the exam as well, but that's probably par for the course working for a startup. What an odd little experience, best of luck!
