Amazon

It was good and nice and very hard to crack, and it is true that Amazon interviews are hard. They asked many questions regarding graphs, trees, and many more.

Applied and then received OA two weeks later. It had LeetCode problems and work style questions. A few days later, I heard back for a technical round with an interviewer. This was your typical LeetCode medium problem (linked list).

Many rounds and technical and cultural fit questions. They track any AI help or dubious practices, so be honest and do not try to be oversmart. Do not try to fake your representation by having someone else take your interview or by Googling.
