Anyone here interviewed for McKinsey SWE 1 (full-time, US) recently? Would love to hear how your experience went. I'm prepping right now and feeling decent about arrays/strings/hashmap type problems and SQL, but curious if anyone ran into anything unexpected like heavier graph/tree/DP stuff or anything outside typical LC medium range. Also curious how the pair coding round felt compared to the HackerRank OA. Any tips on what to focus on in the final stretch of prep would be hugely appreciated.
