Hey!
I figured I could give back to the Leetcode community after failing my first FAANG interview. This is my first post here too so apologies if it's not well structured.

I had a virtual onsite with Amazon about 1 month ago. I went straight to the onsite after passing the OA questions. My OA questions were very easy so not sure how I got so lucky there.
OA Q1: https://leetcode.com/problems/prison-cells-after-n-days/
OA Q2: https://leetcode.com/problems/k-closest-points-to-origin/

The virtual onsite consited of 5 interviews on the same day, one after the other, with a 1-hour lunch break between the 3rd and 4th interview.
They ALL asked me LP questions so you better prepare for those. One of the interviews was purely behavioral (I belive the interviewer was the hiring manager), so no coding on this one.

I do NOT remember all of the questions unfortunately, but I'll write the ones I do remember:

Interview 4 - System Design Question: Tic Tac Toe Game: https://leetcode.com/problems/design-tic-tac-toe/
Interview 3 - System Design Question: Design a Text Editor with Basic Functionalities (I failed this one miserably as I did not know exactly what he was asking me to do. I created something but I'm sure he was not satisfied with it).
Interview 5 - Algorithm and DS Question: Given an array of words, find combination of words which form other words in the array. Example: ['star', 'rockstar', 'rock', 'throw', 'ing', 'rockthrowing']
Answer: [['rock', 'star'], ['rock', 'throw', 'ing']]
I am not sure if there is a LC question for this as I searched but could not find anything similar. Also, I was able to solve this problem but did not optimize it at all. Only did the brute force unfortunately.

Interview2 was purely behavioral, and I do not remember the question from Interview 1 so I apologize for that.

Anyways, I'm not disappointed that I failed. I realized I need to practice more and more before going to another FAANG interview.

Hope this post proves useful to someone.
Good luck!
