Call with a recruiter, then met with CPO about 3 weeks later. It went well and I was told that I would be contacted for an interview to meet the team. Then nothing for over a month. I followed up, but no reply. Super disappointed, as I was really excited about this role, and when a CPO tells you that he will have HR schedule the next interview, I would expect at least a "thanks but we went another way letter" or something. Not very professional at this level. Waste of very valuable time.
