Causal interview questions

The First call was with a Recruiter, we talked about experience, salary range, etc The next round was with an engineer, just a conversation to understand my experience and day-to-day work at their firm. The third round was a Takehome assessment, online 90-minute time limit, with React and redux ui, as I applied for a frontend role.

Interview process was straightforward, three interviews, first two were culture fit type conversations, last one was a mock sales call. Overall, they were friendly and encouraging. I'm not sure why i didn't get the offer, as I got to the final round, and that felt like it went well.
