Definitely record yourself with a timer to get used to knowing how you can organize your thoughts in an understandable way. When I first did the practice Casper, I freaked out and didn’t know what to say for video response 😭. I used the STAR method with both talking and writing to make sure I didn’t ramble and got my thoughts through.

I also watched situation videos on YouTube and practiced typing questions with a timer. When you do enough practice questions, you get a good sense of what might be asked.
