DoorDash Senior Associate Strategy & Operations interview questions

Take home case study immediately after recruiter call. 48 hour deadline, expects a 4-6 page PDF executive-level deliverable making actionable business recommendations for DoorDash, based on a month of DoorDash order data. Expects high-level data & statistical analysis along with strong operational & strategic recommendations, plus polish. Complete ~~malarkey~~ for this to come before even a single interview. I spent ~20 hours on the project and was extremely proud of what I put together, didn't get an interview. This is also after the interview exclaimed about how good of a fit I would be. Seen other people saying it's just for DoorDash to get free consulting, seems outlandish but kind of hard not to agree after this. Whether it's legit or not, the expectation of this level of deliverable is ridiculous for almost any position, especially an associate level role. And the timing of it in the interview process makes it doubly insane.
