An interview with Mark Yamashita, Technical Product Director at Sensibill, a fintech company that means you never have to worry about expense forms again. Mark moved into Product Management from working on supercomputers and compilers, via an MBA. We talk about how technical PMs should keep away from solutioneering, how education & mentoring are so important for PMs, as well as why "Singin' in the Rain" is basically the Lean Startup.   Catch up with Mark here: https://www.linkedin.com/in/mark-yamashita/
