Hey, I answered this earlier on this forum so I'll paste my answer here for your convenience:
I did Pinsent’s blended assessment last recruitment cycle and I do remember one of the video questions being scenario-based. It was based on receiving feedback from your supervisor regarding improving your attention to detail and how you would react and implement this. Obviously the questions must have changed now, but basically do be prepared for maybe one scenario question. The other question was firm-based.
Apart from that, there’s a decent amount of numerical reasoning so keep a calculator and pen paper handy. The assessment itself I found to be quite time pressured given the firm advises you not to spend more than 1 hour on it. But don’t worry, I’m sure you’ll smash it- hope this info helps!
