I have cleared the online test for Amazon SDE 1 role, my recruiter has told me that my interviews will be conducted in their office in the upcoming weeks. And the interviews will be as follows:

1. Problem Solving and Coding
2. Data Structures and Algorithms
3. Hiring Manager

I had a few queries regarding this:

1. If anyone has given an interview with Amazon recently in their office, could you please share your experience? esp whether we have to write code in some ide or on whiteboard.
2. What is the difference between first 2 rounds? is the first round similar to LLD?

PS: I am having 1.5 yrs experience, and the OA Test had 2 DSA questions(easy-medium) for which I also had to give a brief explanation of my approach and Time Complexity followed by a workstyle assessment test (in case anyone is curious about this info)
