Nelsons interview questions

The first stage with the HR partner was straightforward and friendly. The HR partner appeared to be very enthusiastic about my experience. I then heard nothing back for about two weeks and hence decided to follow up. The HR partner set up an interview for me to meet the senior manager I would have been reporting to, but the senior manager simply did not turn up to the interview. I waited on the call for 25 minutes and then sent an email to the HR partner asking if the interview was still on/if they were still interested in interviewing me for this position but unfortunately heard absolutely nothing back. Unbelievably rude.
