A recruiter reached out to me with multiple questions via an email first and then set up a time for a phone call. Less than an hour before the call she emailed me saying that the hiring manager changed his mind and they were not hiring for this position any longer. All of this happened in a span of 2 days. Pinterest is just wasting candidates' time.

Hr interview, hiring manager lead, case study to be presented at the end. They send you materials to prepare for the case study ahead of time, with a few days to fill in the template. The case study is presented to a panel who will ask questions as if they were an advertising client.
