Status: 10 years experienced
Position: SDE1 at Amazon
Location: Luxemburg

Contact:
Contacted by recruiter directly and invited for tech-screening. No online assessment.

Preparation:

1. Solved 100 problems from the Amazon problem list in Leetcode Premium.
2. Prepared LP by identifying and wrting down situations with START format.
3. Gone through free free popular materials of system design interviews.

Initial tech screening:
Occurred during mid March.
LP question: About my current project in details.
Coding: Simple graph problem. Given a list of pairs of friend. Need to find if one of them is reachable from the other one. I used BFS and back-tracking.

5 round virtual onsite:
All the interviews have close to 50% LP question. I'm mentioning here as much as possible.

1. Details of my latest project.
2. My typical day at office.
3. If I had a conflict and how did I resolved it.
4. How much do I face customers.
5. Did I solved any time critical issue and what was the approach/impact.
6. Why Amazon.
7. Why applying for SDE1 with 10+ years of experience. Though 2 of the interviewers were in SDE role while they were senior like me and according to them, in Amazon it doesn't matter
8. If any decesion I had taken, gone wrong and what would I would like to change if I get another chance.

Here are the technical questions.
Round 1:
In the logistic floor robots entered and exited, how many robot exist at any specific time. interviewer was not very specific about the question and I had to question a lot to understand and construct the problem statement.
Round 2:
This was a design question from the hiring manager. Design an application for a Car showroom. I started with gathering detailed requirements but looks like he was looking for more generic low level design or may be I guessed it wrong.
Round 3:
https://leetcode.com/problems/jump-game-ii/
Round 4:
Design of a System to maintain takeoff-landing boarding gates of an airport.
Round 5:
Linux find command implementation. https://leetcode.com/discuss/interview-question/369272/Amazon-or-Onsite-or-Linux-Find-Command. I did and BFS implementation for a n-ary tree

Result
After two long days, got mail from recruiter that I'm notsuitable for the role. I'm totally clueless about where I lacked as I did prepared for LP questions well and answered all confidently. Also I would say I did well in the technical questions. But may be I needed to conquer than just accomplishing.

What I could have do better:
I'm really puzzled about this. May be more speed in solving the coding parts, may be I messed in LP to myself ready for junior role.

I leave the question for the leetcoders.
