1 phone screen, 1 technical interview discussing experience, 1 take-home case study, and 1 final interview to present the case study. The biggest issue was that they expected a whole case study instead of the usual 3-4 hour assignment, all the way from EDA to modeling and inference. It must've taken me at least 10 hours just to get it to a presentable state. On top of that, the topic also seemed directly aligned with the team’s actual work, and it was explicitly mentioned they might explore or use parts of what I built later, which made it seem like unpaid work. While everyone was professional, I still felt like my time wasn't respected.
