Hi! My AC was virtual; I believe Mondays are the only days in the week that are available for virtual ACs. I found the format to be coherent, you 'll probably be receiving a schedule soon for your AC.
For me the day started out with an introduction with recruitment and the rest of the candidates, then straight to the General Interview which took about an hour. Following that, meeting a FF Trainee and talking to them along with the rest of the AC participants. Fifteen minute break following that, then thirty minutes allocated to study up and make notes on an article and then finally, a one hour technical interview on that article.
