I was asked 2 LC hard in Amazon onsite last week, I thought Amazon hiring bar was relatively lower.
I interviewed at Amazon Music last week and was asked 2 leetcode hard during onsite.
1. Merge K sorted lists
2. Word Ladder II
Also, this happened after 20 mins of behavioral questions on LP, so you're supposed to solve LC hard within 30 mins, 10 mins, in the end, to ask the questions to the interviewer.
