hello i did :-)) its nothing to be worried about - they dont ask any technical questions. its three questions that you provide 2min long video responses to. iirc, the questions were:
what do you do in your free time?
why do you want to go into finance?
what interests you about hsbc specifically/why does hsbc appeal specifically?
i might be misremembering them slightly? i answered them pretty badly anyways 😅 good luck to you, though! and dont stress yourself out over it lol
