Straightforward, Power Day is always difficult but cases are structured very similar to the ones they send beforehand. Make practice examples using ChatGPT for harder versions of the case and practice those. Design interview is easy, just be creative and have fun with it. Overall process is long and tedious and honestly pretty subjective. Failed last time around because of a case but passed this time. If one interviewer fails you, you're done so be prepped for all parts.
