Phone screen with CTO in the early afternoon.
He seemed tired and disinterested in conducting interviews. For my part, I found his questions about front end tech pretty disinteresting and probably meandered a bit too much. I felt like the onus was on me to keep up the conversation.
He answered all my questions about engineering at the company. From what I could tell they're still missing a lot of quality-control and project management processes that I have found are needed to scale teams and projects.
