Here's my experience of the amazon sde-2.

R1 - OA + behavior question and standard system design questions.

R2 - 2 coding questions
Q1 : finding maximum length subarray with first and last element having difference k.
solved this within 20 mins from brute force to optimal solution.
Q2 : finding maximum product L shaped path within a matrix.
needed some hints but solved fully.
no LP questions were asked.
I think the interviewer seems satisfied with my answers.

R3 - LLD
design notification system with focus on building message content for different channels.
2 LP questions.

Result
Got rejection email after a week with no feedback. The interview went well though. Not sure what went wrong. Guess interview bar is very high nowadays.

All the best for your interviews !
