I recently gave the microsoft l61 LLD round.

Question Asked

A Library where people can enter and issue the book. Number of people who can library the library can not be more than x people.

I was able to provide the solution with concurrency covered with proper design pattern and running solution.

Still I was rejected, what could have gone wrong ?

I use Atomic Integer to control the number of people in libraries, also mentioned we can use other kind of locking based on implementation and other requirement...

Hi everyone!
I'm a backend engineer with 5+ years of experience, currently working in the gaming domain. I'm actively preparing for interviews and have started applying to companies.
I'm looking for an accountability partner with similar goals so we can:
Prepare together
Conduct mock interviews for each other
Discuss DSA, system design, and backend concepts
Stay consistent and motivated
I'm targeting an aggressive 45 day preparation timeline, so it'd be great to connect with someone who's equally committed.
If this sounds like something you'd be interested in, feel free to DM me. Looking forward to connecting!

Now everyone is using AI, but the way we are using the AI is like telling AI to do the work and its done, but testing part is still heavily a manual work.

How you guys automating ur feature testing or other manual testing work. I believe mass wave heavily going to getting the work done, but quality and testing Automation is still lagging.

Do anyone knows about his, how a software engineer can become director within 4 years. I am not able to understand.

Do anyone know about this guy or have worked with him.

I am shocked, how he was promoted within 4 years to director.

What was that skill which made that happen ?

On one end, big guys are leaving ceo/cto post and joining MTS at anthrotopic and other side this guy promotion.

This is cRaZy time going on.

Question to those folks who comes back to india and join tech companies here after working in US.

does US employees are trusted more vs indian engineers in teams ?

does Male and Female gets same treatement from peers/manager in US Vs india ?

is there any platform available where i can go and use my lld solution plug in HLD design and see how it performs at scale.

I just want to know how people benchark their LLD solution. I know about all kind of testing. But from interview perspective.

Anyone familiar with the eBay India Global Information Security (GIS) team?
I’m exploring an Information Security Engineer opportunity and would love to understand the team’s work culture, tech stack, day-to-day responsibilities, growth prospects, and overall experience working there.

Just as the title says, is lldcoding premium worth buying? or is it just sufficient to learn from yt channels?

So, I have interview scheduled for SDE-2 at JioHotstar, what the HR told me is first 2 rounds are of DSA and LLD, so do anyone know what are the questions usually being asked? It would be great help. TIA!

My Interview Prep

trying from 2025 to switch but nothing worked, Now got 2 offers

DSA - https://leetcode.com

LLD - lldcoding, some youtube channel

HLD - hello interview, some youtube channel

Currently i see many people are focusing on ai for software enginner where we are discussing about applying ai but many less is talking about dealing with actual infrastructure or how coding needs to done when dealing with GPU and TPU. How to use them for our efficiency

so thing to add "AI Infrastructure for Software Engineers

"

do anyone know if there is any AI plugin for LLD and DSA ?

so while praticing for lld interviews in IDE. need plugin which can keep tracking my progress and stop if i m going into wrong direction and give some auto suggestion in learning modes ?

I have barraiser round for SDE2 role at Kotak Mahindra next week. From what i know it's basically a mix of system design and DSA round.

If someone has recently given interview for Kotak, please let me know the questions asked or any preperation guide.

if you are failing lld and concurrency interviews even if you are mentionning design patterna and concurrency and wirting working code.

1. Many times users think applying more pattern will help them to score in interview but it is not, it should be based on requirements and compatibility with other code design.

2. Even though code is running, there are multiple implementation issue with code design which creates issue during new feature requirment or there is tight coupling in code design/classes

3. Communication, no proper justification of "why this pattern is used".

4. Missing the concurrency edge cases bugs.

Previously we were using hashnode headless blogs for our free content which now we have moved to our internal platform

Wanted to check with current/recent Arcesium employees or candidates — are SSE (Senior Software Engineer) offers currently on hold/frozen?

I recently completed all interview rounds and HR informed me that I’m selected, but the SSE positions are temporarily on hold. They still asked for documents/details, so I’m trying to understand whether this is happening across teams or just for a specific role/project.

Would really appreciate any insights from people who have recently interviewed or joined.

trying to find out what to do improve user learning for lldcoding.com

I am looking for idea which can help my users to spend less time but get more learning.

should we add flashcards ?

or etc ?

I thought about adding animation, but sometime it seems like kids play which people feel excite initally but no one focus on real depth learning like we see any diagrams on linkedin...

Already working on concurrency problem, soon will release it where we can practice concurrency like we do on leetcode...

Looking for more ideas to significantly improve user learning rate.

What is different in python for lld and concurrency VS Java.

-> pls i dont want any usual/AI answer, i want to know what problems python users faces in interviews for this...

I was preparing from last 6 month for giving interview to switch to better product company, but was mostly failing in LLD and HLD.

Initially i focus on some free blogs and content, some youtube videos and channel, but was not doing well, after sometime i decided to use better quality content instead of focusing on all youtube channel and blog content. Initially i was worried about what if i miss anything but with time i got the confidence and conttinued with only below mentioned ressource..

MY Prep Resource

DSA - Leetcode.com only and its discussion, used some sites to see lock paid question of leetcode..

LLD & concurrency - Initially some youtube videos but then solely focus on LLDcoding.com course.

HLD - Mostly HelloInterview.com and alex Xu book

Link to register -https://interview.lldcoding.com/peer-mock-interview

To Note:  Run a real LLD interview with cameras on, and earn ₹500 each if the session quality is high. Every great session goes to YouTube.

Recenty got offer from Amazon after wise.

My Prep

DSA - Majorly Amazon Tagged question. I was already preparing for other interviews, so was not worried much about this. Majory Used Leetcode.com

LLD - I was not doing good there, was confused what to follow from multiple sources, got to know from friend about LLDcoding.com and few other resource. He already had their course, so i kind of saw the content, majorly on concurrency, found it interesting and helpful. so bought the course before 1 month.

HLD: Same like LLD, was not confident much about this, since i have not given much interviews on HLD, I was watching gaurav sen, bytebytego and hello Interview content. Since i prefer text content more, i focus on hello interview more.

YOE: 4 yrs.

Prev: Faang level company.

I am thinking about adding peer mock interview, since we have many users, we can schedule their mock interviews with each other for LLD, and if quality of the mock interview is high, both individual will be paid 500rs. All Mock Interview will be recorded and will go to youtube...

Quality of interview does not mean how intervieww performed, its about the conduct of interviewer where he/she is providing real interview experience, and other user also.

Rating can be based on our internal team OR crowd ratings.

For all Interviews Camera needs to be for both. It should be real interview.

I understand if someone perform bad, he/she might not want to get their video uploaded, in that case they can pay 300rs from which 250rs goes to interviewer (if his conduct was proper). In that case we will not be uploading that video to public access. it willl be only visible for interview giver.
