HoYoverse Intern interview questions

Two rounds , first round, resume dive (15-20 min), asked to implement something i mentioned in my resume in javascript, cs fundamental questions (20 mins), leetcode easy/medium, i got a sliding window question (20 min). Second round, hr interview 30 min, technical interview 30 min, 3 leetcodes, medium/hard difficulty, variants on the first question follow ups First round was normal difficulty, second round threw me off, difficulty was a lot higher, and being done after the hr talk made me not expect such a high difficulty (lowered my guard)
