Got an email from HR almost a month after applying. On responding, HR emailed for first round set next day. Round 1 - Interviewer asked questions about background; and experience in Product Roadmaps. HR emailed within an hour asking if available for second round (I was impressed with the turn around time here!) Round 2 - It was a bridge call and unfortunately I dialed-in late. Hiring manager asked about Product Roadmaps. After a week, I emailed HR asking if there is any interview feedback, since I had not heard back (and assumed was rejected). To my surprise, HR informed that Hiring manager wanted third telephonic round. I agreed and it was set for 2 weeks later. On the previous day of interview, the HR called saying there has been confusion, and it was an in-person round. I agreed reluctantly, as I did not want to push this process further, myself. Round 3 - I went in and was greeted by the initial interviewer I spoke to. A set of slides were put on on display with around 30 questions; and I was asked to answer them. Most questions were irrelevant which the interviewer agreed as well. Interviewer revealed that the questions were compiled by the hiring manager. Next, I was given a six-pager case study on screen for 6 different products; and asked to come up with a Product roadmap, prioritize and present as a PPT in 15 minutes! I was shocked and clarified that I would not be able to come up with any valuable outcome in 15 mins. Response: "We were supposed to mail this case out to you prior to interview so that you could come prepared with the analysis, but we missed out. Unfortunately, I still need to run through this piece to complete the interview" I knew it was a failed chance. I still tried and gave a rough PR layout, and what the deciding factors would be for prioritizing, with some heavy assumptions. Never heard back from HR on checking for feedback.
