The first interview was with the recruiter, then with the hiring manager (it was with the owner of the company) which went well. The next stage was a personality test and then a call where they went through the results with you, telling you what your personality is based on the results. I was rejected with a template email after that call. I think at this stage of the interview, especially after spending the time on the preparation, some more personalised feedback would be a decent thing to do.
