I interviewed with the NHS, I found the interview to be fairly easy going, nothing too stressfull, the interviewers were welcoming and friendly. I wasn't asked that many questions, so be prepared to be expansive with your answers

Overall good, included some role play, group interview on scenarios, then 1-1 interview. Supportive team, panel of 5 members of different disciplines, would recommend using STAR format when answering questions and writing questions down as they usually had two parts and you wouldn't want to forget anything.
