“Talked through it step by step and kept pausing to ask if my reasoning tracked.”
“This looks like a textbook question until they ask the follow-up about nearly sorted data and you realize you picked quicksort as your lead example.”
“Classic Bayes setup.”
“The setup sounds clean but I fumbled the assumptions part at first.”
“This wrecked me a little.”
“I got through the derivation okay, took the gradient, set it to zero, got to (X'X)^{-1} X'y without too much fumbling.”
“The bold strategy part is what makes this annoying.”
“Set up three variables and the leg count equation.”
“Set up the variables fine, cows = x, chickens = 2x, spiders = 4x.”
“Straightforward on the surface but they wanted you to walk through every step out loud.”
