Little over a month long. Logistics were not great due to overstretched support staff. People were great though. Phone call with CEO talking over company challenges, what he wanted in the role, what I was looking for in a next step. In house meeting invite got messed up, but I offered to come over late and he stayed till 8pm to meet me at office. Went through story of company, what he was looking for, what his vision for the company and culture was, etc. Was a very open-minded conversation. He was fast and intense, but listened well and appreciated when I pushed back on something. Left impressed. 3 more meetings over the next couple weeks. Wide range of topics. Did a project to show how we'd work together. By the end, was pretty impressed with Zack, the CEO, optimistic on the company, and liked my future teammates. Def did not run smoothly logistically so work needs to be done there.
