Bain R1 in <1 week

Hi all!

I have my Bain r1 coming up in a few days which consists of 2 30 minute case interviews. I've been doing candidate led interviews with my friends, but I feel as though I should narrow my scope now. What (specifically) should I be be putting my time and energy towards these last few days? Should I focus on a specific case type? Put an emphasis on speed?

Additionally, should I expect any PEI related questions or prepare anything specifically (behavior wise)?

Would love any and all last minute tips tricks and recommendations :)
