The first step was scheduled as a 30-minute hiring screen. The hiring manager was professional, kind, and generous with his time. He gave me a 90-minute behavioral+technical interview as that first meeting, which included answering many questions for me. Despite poor performance in technical questions I had yet to prepare for, I was allowed to progress to the next step- an interview with another executive. That second interview was primarily behavioral. It was about 45 minutes long and pleasant. After the second interview, I was immediately told I could move on to the main portion of the interview process. The hiring manager gave me two written exercises to do. One was designing a product; the other was more technical. As part of this stage, I had two meetings with the hiring manager, totaling 2-3 hours. After submitting my exercises, the hiring manager told me within 24 hours that I would progress to making a presentation to three executives. It was scheduled for about a week later. The final interview/presentation was about an hour long and formal, with highly-specific critique. I received a thoughtful rejection with detailed feedback less than two business days later.
