This is a tough one. I like to think I have a wide knowledge of what everyone in the company does, but it’s not a deep knowledge of any individual role other than the ones I am closest to. So in that sense, every Q&A is just as enlightening to me as I get to learn more about that individual both as a person and with the work that they do.
I think @DillonV has a really unique experience living in LA and working for us, and for a long time being the only person not in the UK, so his Q&A was super interesting.
I also think we often take for granted the fact that @Tom stands up every week in our All-Hands and that we can all ask him questions, so to see the level of activity and buzz on here when he did the Q&A was really awesome.
Also @GeorgieParmenter is such a wonderful person and I could literally hear her voice in my head as I read her answers so I think her one was super fun.
The truth is that they are all super fun to read and I really enjoy getting to facilitate them. Quite a few people in the office have told me they look forward to them every week as well so I know that they are appreciated both inside and outside of the company 
I think they really sum up what Monzo is about. Back when I started (anyone who was here in 2016 and early 2017 will remember) we had a thread where a person in the company would post about what they were working on and then “pass the baton” to another staff member. I really loved reading those when I started, but with nobody to facilitate them, people often forgot to do them and it fell apart. So this idea sprang out of that, and I have to give a massive shoutout to @Chrsm for being the guinea pig for the first ever one.
