Over Zoom I met with the CMO. The conversation went well and I arranged to meet with the head of product as well. That conversation also went well and I was asked to meet with the CEO. On the day of that interview, they weren't prepared for me, and the in-person interview was only 30 minutes. There was quite a delay from that to follow up with the CMO, who then asked me to draft a detailed plan of how I would improve their lifecycle marketing program.
I asked some follow up questions, but was met with very generic responses. I never heard back from them after that exchange. My thought is that they were looking for people to do free consulting work during this "interview" process. The CMO seems very inexperienced and overall the process was not very professional.
