I appeared for Amazon SDE-1 Interview this year in march'20.All interviews were conducted online on Amazon Chime because of COVID-19 outbreak they mentioned this earlier in the mail itself.

I was not prepared for the interviews at all but I thought to give it a shot.
In each round I had to code my solution on their Amazon Live code.

Round 1
Q1 : Optimally search an element in row wise and column wise sorted matrix.
Q2 : Given entry and exit time in seperate arrays as input of each individuals tell the minimum number of chairs required to accomodate.

I was not sure if i was able to clear the previous round because it took me a long time to explain the interviewer solution of Q1.

Round 2
The same day I received a call from recruiter about another round
Q1: Don't remember exactly :
Given a binary tree print all the nodes of that level which have maximum sum.

I implemented a similar problem. It was my bad while implementing I took it for an another problem 😅 but after the feedback from the interviewers I corrected my solution immedialty.

Round 3 (Design )
Lot of questions on leadership principles and my past experience.
Parking lot design problem.
Interviewer was a SDM at Amazon.

Round 4
Again lot of questions based on leadership principle and past experience.

Q1: https://leetcode.com/discuss/interview-question/124719/Find-the-first-word-in-a-stream-in-which-it-is-not-repeated-in-the-rest-of-the-stream/

30 mins discussion and coding.
I was able to solve with some help from the interviewer and he seemed to be satisfied.

Till this point I had not thought I would be able to make through that many rounds.

After 3 days I got a call from recruiter for another coding round.

Round 5 (Bar Raiser) :
Interviewer was himself had very less experience at Amazon . A little discussion intro on current experience.

Q1: Given a Singly list modify the list in a way such that all elements every alternate element is replaced with an element from the end of the list.

e.g. input : Coding
output : Cgondi

He wanted an optimal inplace approach.I told him the approach but I made a lot of mistakes while implementing it and missed few edge cases.He was satisfied the solution.

Next day I got the rejection mail and the recruiter confirmed this on call.
