The initial interview was fairly casual with the Head of Data Science at the time (hiring manager). He's knowledgeable to a degree, given his Physics background, etc. When speaking with him, it's a very small-scale operation and not well-defined. I think the most disappointing part was the feedback, which took a month to come back and didn't include any recommendations or solid reasoning. I would avoid it unless you have a public-sector preference only.

Had two rounds of interview with the ASA, the first a screening kind of call with the manager of the role, the second more of a technical interview with the same manager and a colleague - it would have been good to have known beforehand that this would involve some mathematical questions. I was ghosted after the second interview and only heard back 10 days later after I had to chase for an update. Comes across as unprofessional to leave candidates in the dark, and likely speaks to wider company culture.
