!process Amazon Interview(i fcked up i

[spice kelp]

Three Rounds

1. LP + LLD... LP was fine ...

LLD was something like Imagine you have leagues, leagues have conferences, conferences have Divisions, Division have teams, team have players... and in last he was like Design a Statistic system based on this

I got confused asf and managed to make maybe class structure.... very bad round i guess

2. All LP.. went well

3. 2 LC Medium i guess. First one was Infected person in hospital... kinda solved it using BFS... 2) Was LinkedList ... separate the even from odd

for second question i sugges a solution with TC O(nlogn) and SC O(N) .. and he said modiffy the list iteself.... i was writing the code and coding platform closed automaticlly.. time got completed

Wishing the best for u 🙏 what were ur LPs?

[spice kelp]

Dive deep

Critical feedback

Exceeded expectations

And lot of follow ups

[thin laurel]

all the best!

praying 🙏

[spice kelp]

thnks

[solar anvil]

praying for u brudda

[delicate raft]

Praying for u bro, saw u grinding in every amazon process post for a while, 🙏

[bronze fog]

All the best!!

[rose birch]

hopefully you get it

[rich cairn]

bro was the first reply on every zon post 😭🙏🏻

[simple roost]

Bro, are your 2 LCs these
Is your first LC similar to rotten oranges problem - https://leetcode.com/problems/rotting-oranges/description/

https://leetcode.com/problems/odd-even-linked-list/description/ - seperating even and odd indices from linked list or was it more like seperating even and odd numbers?

[spice kelp]

Second one was little different it was like separate the numbers not via indices

Amd first one was yeah like this but had matrix with 2,1,0 and x representing walls

[simple roost]

Oh.. then what was the criteria?

[simple roost]

0 representing an empty cell,
1 representing a fresh orange, or
2 representing a rotten orange.

That was the question; so if x represents walls; what is 0,1,2

[dusk bison]

I imagine it’s the same and walls prevent the spread of infection

[simple roost]

So technically 0 and x means the same here, right?

[spice kelp]

It was similar to rotan oranges only.. small chnges

[spice kelp]

2 is infected person, 1 uninefected,0 empty room, x is wall

[dusk bison]

Ye so X and 0 prob the same

[spice kelp]

X is wall you camt pass that

Not same

You can move thru empty rooms

[dusk bison]

Right, but unless I’m missing smth I don’t think there’s a logical difference between walls and empty rooms

It’s only in semantics

[spice kelp]

No you cant pass those … if a while column or row is of wall

You wont be able to pass it

Its kinda same as rotten oranges

[dusk bison]

If a whole row or column is an empty room the disease can’t spread either

[spice kelp]

Yeah it was like rotten oranges with some conditions… i asked this to him he said yiu cam move thru empty rooms

So i coded accordingly

And i confirmed about 2 also… he said there will only be one 2

So i coded according to conditions he mentioned

[simple roost]

BTW, what was the criteria for this question? If not via indices, what was the condition to separate numbers?

[hushed drum]

timeline?

[vernal loom]

what did they want you to do with the infection problem? Find if it's possible to spread the disease to every uinfected person? Or find the time when everybody gets infected?

[spice kelp]

He said to return true or false.. like if it spread to all return true … otherwise false… so if any 1 remains in end …. It means false

[vernal loom]

ok i got it

so it's essentially running BFS starting from the infected person (2)

tks

[spice kelp]

Yes

Atleast this what I understood from his requirements and did

[bronze fog]

Can we repeat LP stories in other rounds?

[spice kelp]

when was your interview?

[spice kelp]

No idea … i couldnt solve it

The way I understood was like he wanted info of game stats

At end thru some functions

So we have to store that info

I made a class Match to basically store a match info like which teams played, how many goals were scored, which team won etc… and i made hierarchy like Leagues have conferences, conferences have Divisions, Divisions have Matches, matches have teams, and teams have players… and in end a Stats class which will have leagues… something like this…

I couldnt reach to a point where i would design functions time was over

[thin laurel]

no they are basically not asking any coding question which are available on leetcode?

they are coming up with their own lc questions?

daamn !

any resources you would suggest?

[spice kelp]

Dnt knw man… maybe my approach was wrong… didn’t get much hints either and i got confused so couldn’t manage to do much

[dusk bison]

praying for pizza ood and no hard lc

[thin laurel]

what is RNG?

[dusk bison]

random

[thin laurel]

oh okk

[simple roost]

But aren't they related to any of the standard LC questions?

[simple roost]

+1

[thin laurel]

dont know i havent given the interview yet

[simple roost]

When's your interview? SDE-1 VO?

[thin laurel]

i didn't get the survey link yet

[spice kelp]

what was the ques?
