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.

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.
