Hi,
I recently gave an interview for Amazon SDE 2 role. I felt 3/4 rounds went well and one round I was not able to finish the coding question as the LP based questions in that round were for 40 mins and got only 20 mins for the coding question.
I cannot disclose the exact questions but I can give an idea on what questions I got.
Onsite Interview:
Round 1: Able to solve using topological sort -Similar to Course Schedule
Round 2: One BT question - its in amazons explore card
Round 3: System Design Similar to Google drive
Round 4: Merge Intervals variant not in leetcode
Overall nice experience. I felt I did fell in LP's and coding questions as such. But got a reject :) But leetcode really helped.
