1-hour hackerrank (3 programming questions and 1 SQL), two 30-min back to back phone interviews, followed by a take-home project. Rejected after the take-home with no feedback after getting an email addressed to the wrong name with several typos. Took several emails of follow-up to clarify whether I was indeed rejected.
The take-home easily took upward of 30 hours to finish with the 16GB 311 calls to download, process and analyze. I felt like the company invested as little as they could in the process and then haphazardly sent out rejections. Almost felt like they outsourced their work project, gathered whatever insight from interviewees, and get rid of you as soon as possible. Very poorly designed interview process and probably not worth your time.
