Alzheimer's Research UK Research Informatics Project Manager interview questions

I applied online through Indeed. I received a phone call maybe a week or so later to let me know I had been shortlisted and I was given the option to choose between a selection of times on the selected interview date (of the following week). Everything was very organised and I felt that this allowed me to prep and feel generally relaxed ahead of the call. A couple of days before the interview I submitted a presentation which I had been asked to do, which would explain why I felt my experience & skills best matched me as an individual, to the job role. The call went really well, there were two people who interviewed me. They were both very friendly, so I felt very at ease and the interview went very smoothly. I presented for around 20 minutes and then they had prepared a series of questions for me. The interview was around 90 minutes long. I felt that I had really impressed the panel and they had also asked questions that fell out of their prepared list with I answered well. I was told I'd hear back from them (whether I had been successful or not) by COP that week (my interview was on a Tuesday). I didn't hear back until the following Wednesday from the recruitment department within ARUK that they still hadn't made a decision and that they'd be in touch when they had. It wasn't until the Friday on that second week that I emailed chasing for an update. I didn't hear back again until the following Monday (13 days after my interview and 8 days after I was told I'd have answer from them) that I hadn't been successful. Considering that I had made the panel aware that I was unemployed, I felt it very unfair to be left waiting as long as I had been. I sent my feedback to the company but I never heard back from them so I don't think had any time for me and they made no effort to help me with any interview feedback for my future job search. Luckily I haven't had that experience with any other company or organisation that I have applied or interviewed with since. I have been completely put off applying for a position with this organisation again after such a disappointing experience and I know others have had similar experience which is such a shame. I have however now fallen into a wonderful role within another organisation which I enjoy very much!
