The first interview was relatively chilled out, and guy was very polite. Spent first few minutes introducing company and was only about 30 minutes in total. Had a few technical questions but not too much in depth

I was told at the start that it wasn't an interview and more of a "get to know you chat". Most of this non-interview was a sales pitch about the company with the non-interviewer stopping occasionally to ask me a question. By the end they had all but said I would be heading to the next round for the start of the real interview process and that I should hear back in the next couple of days. I didn't hear anything from them for the 12 days so I sent a follow up email asking for an update only to receive a generic rejection email in response.
