Timeline

December 2021
Approached by a hard working Amazon recruiter on LinkedIn in December 2021. Did OA in December 2021.

January 2022
Heard back results for OA in January 2022 (thought I got rejected). I also skipped the phone screen.
I work a day job so it is difficult to schedule final onsite interview. Scheduled final onsite February 2022.

February 2022: Final onsite and offer call.

I'm honoring NDA, but will give as much details as possible.

OA

Done this quite a while ago, so don't remember the exact questions. Needed to also state and explain the run time complexity and space complexity for the coding questions.

1. LC - Easy/Medium array question. Similar to organize logs into certain format.
2. LC - Medium grid based BFS question.
3. Bunch of work place simulation questions.

Onsite

4 rounds of 60 mins interview. All 4 rounds were similar format.

1. 2 LPs. 1 LC easy/medium with tons of follow-up. Similar to one of those parentheses question. Started out easy, slowly becoming more and more complex. At one point I thought it would became a calculator question, lucky it didn't.
2. 2 LPs. 1 LC medium involving heap. Talked through code to make sure I caught all edge cases.
3. 2 LPs. 1 LC medium involving tree. Struggled a little but interviewer helped, and I could finish the code.
4. 2 LPs. I was asked OOD, but wasn't prepared for that as I mainly prepped for HLD. Some work experience helped here I guessed.

I was able to solve all coding questions, with good discussion on run time complexity and space complexity. Had time to ask questions at the end of all rounds. Generally, I thought all went well and had the opportunity to "interview" the team too. :)

Remarks

Overall, I believe Amazon focuses a lot on LPs, as the company develops their product based on the LPs. For coding preparation, I mainly focus on FB's pure coding questions, and practice talking through the approach. I heard/believe technical communication is extremely important in interviews like these. In addition, ask a lot of clarifying questions, the initial question statement is often very vague and you could guide the question to something you are familiar or solved before. I also try to participate in weekly and biweekly contests whenever possible as I think it simulates the scenario where you have to solve questions within time constraint.

On hindsight, I think I could have tried for SDE2 at Amazon. Live and learn I guess...

Thank you for making this far. Good luck everyone.
