Ultra PCS interview questions

I applied online and was invited for a screening call shortly afterwards. Following that, I was invited for an interview with the hiring manager. The advert had a generic section about offering flexible working where possible, and obviously this is the sort of role where hybrid working is usually fine. Nothing was mentioned in my screening call and it was only during the official interview that the hiring manager asked if I was aware it was on-site full time. Seems a complete waste of everyone's time to let it get to that stage without being clear about this. I also found the interview with the hiring manager (who is the Talent Acquisition Manager, ironically), quite uncomfortable as she didn't smile once and didn't try to build any rapport. It felt more like a disciplinary than a meeting with someone I might be working with.

Had one interview on MS teams. Interviewed by two people: a senior engineering manager and a careers manager. I was asked a lot about one of their military products, guided technical questions, they were very nice. I was under the impression that, if successful, I would be asked to another interview, but they made me an offer after this one. Interview was around 1hr15 long (was originally meant to be one hour)
