I had a pleasant first interview with a recruiter, followed by nice conversations with a peer and the director of the department I was applying for. A fourth interview was changed at the last minute but I was assured by he recruiter that I was the leading candidate and that a case study was all that was left. By the time I finally was able to present the case study (by now we were over a month into the process), I had already seen many red flags: everyone seemed overworked, exhausted, and under constant pressure; and the three attendees of my case study presentation looked tired at best, and disinterested at worse. I don't think I did a terrible job, at least not based on the few questions they asked (though it should be noted that one of them seemed to be doing other things most of the time), and in the end I never found out how I did, because after 5 rounds of interviews and more than a month I went from "the number 1 candidate" to being ghosted like some tinder date. It seems that OwnBackup is too tired and overworked or just can't be bothered to have the decency to explain a candidate who went 5 rounds that he is not getting the job.
