Interview consisted of three interviews - including two cases studies. The process did not seem to have been strongly thought out or have serious guidelines. The first interview was a case study involving a math focused case study, the second was with the hiring manager to go over my resume, and the last was a final case study. Why do two case studies? Why did the HR manager hardly discuss my experience in the second interview? And what was the virtue of doing a second case study interview? Despite having spent a total of 8 hours interviewing and prepping the case study, I received a generic response saying I wasn’t what they were looking for. Waste of my time.
