[proud roost]

LLD/LC?

[subtle shoal]

this guy rly is thanos

[thin slate]

LC , but last round had LLD style question but not fully. Interviewer wanted to see my design skills though

[mild drum]

what were the questions? like hints maybe

[thin slate]

Multi source BFS question where we need to fill signal strength from some specific tower location - 2D matrix, largest area of histogram, a sliding window question something to with strings and the last round like designing rate limiter kind of not fully LLD, kind of Lc style . Had to implement functions such as allow request , clean old request, reset limit

Nothing overwhelming

[mild drum]

okk cool

[mild drum]

you got three LC questions?

and another LLD

[thin slate]

Yes

[mild drum]

ohkk .. usually its 2 lc and one LLD or Lc

[thin slate]

I was able to complete area of histogram question pretty quick so interviewer asked me one more. Not sure why

[mild drum]

ok

[thin slate]

Less LP in that round

[mild drum]

ohkss

what LP were mainly asked

[thin slate]

But I would say they expected a lot in LP he asked many follow ups and wanted me to explain what I learnt how I made choices and what are the things I considered while making choices

[mild drum]

ohh okk

[thin slate]

Tell me about a time kind of questions STAR method. I prepared them already for meta so just dumped everything I had 😅

[mild drum]

yeahh preparing those... but follow ups scks

[proud roost]

any recs to prep for lld

[thin slate]

Getting an unexpected follow up is headache

[thin slate]

I used a Udemy course which I got free from “coding minutes” I think YouTube is enough to prep

[proud roost]

coding minutes ?

[thin slate]

Just make sure to drive the interview all by yourself. Interviewer gonna give you very vague question, try to trim down the requirements by asking many questions, agree on all the features you need, talk about all the entities you will have and relationships you would make, talk about cardinality of those relations one to many, many to many etc, talk about fields you would involve, keys blah blah, then show your oops skills by implementing couple of classes show if you are java guy then show encapsulation with private fields getters and setters, show abstraction by layering service classes with encapsulation, show some inheritance then he’s gonna ask you to implement couple of methods that’s the time got you to shine, show design principles, if you can then use design patterns too , if you don’t have time atleast mention how you would use these patterns too achieve other features - you gotta drive your interview and make it conversational , communication all the time. Huh

[vapid spindle]

Are u referring to this for the histogram question? https://leetcode.com/problems/largest-rectangle-in-histogram/

[thin slate]

Yes

I initially mentioned a solution with multiple passes but the interviewer wanted one pass solution

[vapid spindle]

Is the role for SDE I?

[vestal shell]

seems like it

[grim echo]

when you say keys here is this referring to SQL? did you have to do schema design or query writing?

[thin slate]

Yep

[thin slate]

I didn’t do any schema design and querying

Because my question is LLD style Lc

But I was talking more in general

I did a LLd with Salesforce, and that’s how it went for me

[quasi kelp]

International student?

[thin slate]

Yep

[quasi kelp]

Congrats! still waiting on a response after OA lol.

[thin slate]

I guess luck plays important factor. I have seen many candidates receiving interviews with partial acceptance and some candidates with all test cases still waiting lol

[quasi kelp]

yea, not sure how they pick after OA, passed all tests and thought the job sim went well.

[grim echo]

but it's not like system design? like you don't have to talk about servers, scalability, DBs, it's just design classes and functions?

[thin slate]

Yes no serves scalability. It’s LLD not HLD

[deft ingot]

Did you reach out to the student recruiting team after onsite for response? I think i did well in the onsite but haven't heard anything for like 2 weeks

[eager nymph]

that is a long ass time wtf

[willow steppe]

.

[candid mural]

Any recommended source for LLD and LP?

[buoyant storm]

Following

[reef cloud]

Do they give the location before or after the final interview?

[thin slate]

They ask location before interview

[reef cloud]

Oh they ask for your location pref? I haven’t been invited yet or anything

[thin slate]

Yes

[mild drum]

do they ask questions like Why Amazon? Weakness and strengths?
or beh is strictly LP related?

[mild drum]

okk what other LPs were asked?

[next wharf]

hey man congratulations! can you link the course or what name is it

[thin slate]

https://www.udemy.com/course/low-level-system-design/?srsltid=AfmBOoq6zdjOUndtsIyoyanFXJYcFLkPL1izoMnwkk_swbKHVyEDpbpN&couponCode=ST3MT200225B

[grim echo]

do you think that's worth buying? Was a lot of it really important for the interview?

[thin slate]

I got it for free during new year time. He gave some coupon. I think YouTube is enough no need to buy anything new

[grim echo]

thank you. also for LLD do you have to talk about concurrency and multithreading?

[thin slate]

No and don’t try to initiate that path if you can’t handle them. Even if you do I don’t think it’s gonna be big deal they might ask you how you would implement concurrency control in a booking system where multiple users try to book same slot, at that time you can talk about things like row level locking, optimistic locking , explain their ad/disad of both blah blah same with mutli threading

[grim echo]

got it thanks!

[grim echo]

also do you have to test your system after you design the LLD? and same for other techincals do you have to write tests?
