NHS interview questions

I had an interview with two staff members. It seemed to be a very rushed interview and they didn’t seem informed of the job vacancy nor could they answer many of my questions properly. They told me they would let me know the outcome the following week, it has now been over a month and no response... it seems very unprofessional.

Applied via indeed and got invitation to interview.The 3 interviewers were polite and asked pretty easy questions to start with, generally strength questions or questions about work experience/volunteering I did. Couple of technical questions at the end.
