The interview process started positive, completed the early stages with the hiring manager, leadership and colleagues. Spent 10+ hours prepping for "The Challenge", and got positive feedback. Was asked to visit the office in person, with the clear expectations of "just meeting the team", only to get ambushed by a random higher up who had no idea who I was, anything about my background. He went on a full ego-trip, asking absolutely random questions, and I left feeling flabbergasted. They then requested I spend another hour with this person, where he again asked irrelevant questions like someone who learned how to interview by reading a manual. Blessing in disguise that I didn't get an offer.
