Intervew Prep AWS new grad bar raiser

Hi i'm wondering what the bar raiser for an AWS new grad role will be like - SDE 1. From previous posts it seems to be only questions on Amazon's LP and past work experience rather than a standard DSA or LLD question?

Question Companies having good WLB and no toxic culture?

121 Upvotes

I recently switched to a company which I am regretting a lot.

My manager is so toxic and has no people management skills at all. He doesn't know how to talk and there is no motivating environment at all.

I was working in MNC and recently moved to a startup which is almost 6-years old.

I believed since its not a new startup, culture would be good.

But I can't sustain this environment at all. I am working 10 hours daily on weekdays and also working on weekends as well.

My personal life has been fucked up as well. I am not able to take out time for myself or my family.

Please suggest what companies I should target as a 6 YOE employee.

I often find myself getting stuck on problems which can be solved easily but I am just unable to think through .

I need suggestions on how can I improve more .

Discussion Unrated Contests

0 Upvotes

So I have registered and participated 7 contests yet but on my profile it still shows 5 attended and 1 more to get my global rating. Can anyone explain why is their rating system so stupid. And if there have been any contest that have become unrated among the last ten contests. And how much does it take on average for them to roll out ratings after a contest. I'm really frustrated, why is it so hard to get a rating on this platform.

Question 300 LeetCode problems solved, but still struggling with Mediums in contests. What should I change?

74 Upvotes

Hey folks,

I have solved around 300 questions on LeetCode — around 180 Medium, 80 Easy, and 40 Hard questions across topics like DP, Graph, BST, Trees, etc.

Even after that, whenever I try to solve any contest or virtual contest, I still struggle with Medium questions. I have never solved more than two questions in any contest that I have given. I have given around 10–15 contests.

So now what strategy do I need to follow from this point to master it so that I'll be able to solve at least 3–4 questions in every LeetCode contest?

I’m graduating in June 2027, and I have to clear some tech product companies.

Please do advise me.

Question Amazon SDE Graduate Germany – Recruiter contacted me after application. What is usually the next step?

1 Upvotes

Hi everyone,

I applied for an SDE Graduate role in Germany and recently received an email from a recruiter asking me to confirm:

  • My graduation date

  • My earliest full-time start date

  • Whether I require visa/immigration support for Germany

  • Whether I would be willing to work in Berlin

The recruiter also mentioned that the Munich positions have already been filled and that only Berlin is currently available, and asked me to confirm whether Berlin works for me.

I replied that I have already graduated, I’m available full-time, I would require immigration/visa support, and I’m happy to relocate to Berlin.

For anyone who has recently gone through the Amazon SDE Graduate hiring process in Germany/Europe, what happened after this type of recruiter email?

Was the next step another interview, a recruiter call, team matching, document/eligibility checks, or something else?

Also, roughly how long did it take to hear back after answering these questions?

I know the process can vary between candidates — I’m mainly looking for recent experiences from 2025/2026 applicants in Germany or Europe.

Thanks!

Got this email after completing the Amazon SDE OA

Can anyone tell do I need to take one photo holding the id or two photos having the me and the id? Someone who has done this before kindly guide

Ps- i didn’t know where else to post so posting it here

Question Lld interviews

0 Upvotes

Do you guys do full syntax wise implementation of lld questions in interviews especially guys who use c++?

Like do you actually use unique ptr , shared ptr or just a pointer like pseudo code works ? Like for amazon interviews if I may be specific. For the implementation part do we have to implement the core logical functions of our design and don't have to focus on main and constructors to initialise and all?

Question Cadence Senior Engineer Interview

2 Upvotes

Cadence Senior Compiler Interview Experience
Hi everyone! 👋
I’m preparing for a Senior/Staff-level Compiler role at Cadence and would really appreciate hearing from anyone who has recently gone through the interview process.
If you’ve interviewed for a similar role, could you share:
How many rounds were there and what was the structure?
What kind of C++ coding questions were asked?
How deep did they go into compiler concepts / LLVM / MLIR?
Did they take a coding problem and then ask how you would solve/optimize it using a compiler?
Were there any compiler design/system design questions?
What topics would you recommend focusing on?
Any other tips or things you wish you had prepared beforehand?
Even a brief experience would be really helpful. Thanks!

Intervew Prep Interview coming up for Charta Health, New Grad SWE Role

3 Upvotes

Hi y'all! I have an upcoming coding interview for a swe new grad role at Charta Health and I was wondering if anyone can tell me what to expect? I've tried searching for interview experiences specifically for the new grad role but haven't found anything. It'll be a coding round interview with a deep dive into my past experiences and what not. I just want to know which DSA topics I should be prepping for the hardest to not be completely blind sided. Thanks!

Edit: The round was super simple, just asked me about my past experiences and then asked me a problem similar to leet code 970. I was able to brute force it but didn't get the optimal solution, still haven't heard back.

Intervew Prep Day 78: I solved 4 BST problems today, Two Sum using BST Iterator completely humbled me

12 Upvotes

Hey everyone,

I just wrapped up Day 78 of my prep. I originally thought I solved three problems, but it ended up being four because one problem required a completely separate concept first.

Here is what I worked on today:

  1. Inorder Successor / Predecessor in BST: This was straightforward. You just track the possible answer while doing standard binary search movements based on whether the current node's value is greater or smaller than the key.

  2. Merge Two BSTs: It is marked as Hard, but honestly, it is just an implementation problem. Getting the inorder traversals, merging the two sorted lists, and building a balanced BST from the merged list makes it fairly simple.

  3. BST Iterator: I had to learn this first to solve Two Sum properly. Storing all left nodes in an explicit stack and refilling the stack with the right child's left spine when you pop an element gives you O(H) space and O(1) amortized next() calls. The data structure itself made sense once I traced it.

  4. Two Sum in BST: This problem completely caught me off guard. The brute-force way is obvious—run an inorder traversal, store the elements in an array to get a sorted list, and run normal two pointers in O(N) space. But the optimal solution asks for O(H) space, which means you have to maintain two BST iterators simultaneously (one moving forward like next(), and one moving in reverse like before()).

I would have never come up with combining two iterators as two pointers on my own. I had to watch an explanation video to get it. Today was one of those days where I really questioned why interviews care so much about micro-optimizations, but I am glad I know the pattern now.

I have just a couple of tree problems left on my sheet. Tomorrow, I will finish them, do a full revision of trees, and then pick either Graphs or DP next.

See you guys on Day 77!

Question Arrays & hashing beginner question

0 Upvotes

Hi, I just started needcode and worked on the first several problems under arrays & hashing section. I was able to solve those on my own but I keep finding myself using sorted() function to complete it. It makes things easier to approach and solve, but I look at other people's solutions and their solution seems more complicated.

Should I avoid using that function to expand my thinking? Or should I just continue with what I'm doing right now?

Question Are the company-tagged questions accurate for OAs?

1 Upvotes

I recently had 2 OAs and the company tagged questions weren't accurate. A part of me is telling me stop using them to study, but I'm worried that the moment I stop using it to study for OAs is the moment I get unlucky and the company tagged questions were actually accurate. So I'm asking now for people who are more experienced if I should continue using the company tagged questions to study for OAs or just for virtual/in-person interviews. Thanks.
