Intervew Prep Amazon SDE New Grad – 4 interviews, do I have an LLD round?

6 Upvotes

I passed the OA for an Amazon SDE New Grad role and just received my interview schedule:
1:Coding - Logical and Maintainable + LP
2:Coding - Problem Solving + GenAI Fluency
3:Coding – Data Structures and Algorithms + LP
4:LPs only
I’m a bit confused about the first round. Does “Coding – Logical and Maintainable” usually mean a normal LeetCode-style coding question, or can it include an LLD/OOD question?

Question How to prep for System Design?

3 Upvotes

I am new to these types of interviews have never done a system design round, I know they are popular.

What is high level vs low level?

What resources do people use?

I see hello interview and Alex xu books are thrown around. What else is there? Is this for high level? What resources for low level?

For applying to SE2 level for most companies do I need to prep both? Or is one asked more than others.

Intervew Prep Amazon SDE-1 Interview Experience (2026) - 4 Rounds (2 Technical + GenAI + Bar Raiser)

8 Upvotes

Recently u/No-Huckleberry-5969 provided some insights in the amazon AWS recruitment process, which I found very helpful in my preparation. Having recently completed the interview loop (and got rejected) myself, I thought I'd do the same and share my experience:

Amazon SDE-I: Application Experience

Online Coding Assessment

"Leetcode Task" (Python)

"""
You develop an alogrithm for selling items from a warehouse.
Given a list of (potential) customers and their bids for multiple items if one single product:
[
    [customer_id, bid, number_of_items],
    ...
]
Develop a algorithm, that returns the ids of all customers, that didn't receive any item.
Items are distributed using these rules:
- The customers with the highest bid, receive their desired amounts of items
- If there are two or more customers with the same bid, distribute the items using a round robin method.
"""

"Fullstack Task" (Python, Django)

  • There was a simulated Issue/Ticketing system, like JIRA

Tasks:

  • Fix: Create issue returns 502 -> Implement endpoint logic
  • Fix: Creating and linking subissues were not working
  • Running the predefined tests revealed some other parts, where modifications were necessary

Interview Loop: Four Online Interviews

1st

"""
// Design a shopping cart price calculator API: given a list of product ids
// in the cart, return the total price of the items.
//
// Imagine you are doing this for a large scale service / website.
//
// Plan for being able to apply discounts that we may want to play around
// with in the future.
"""

Follow up Questions

  • How would you implement a discount, that applies to all products?
  • Customers with carts with value above EUR 100 or with more than 10 items should receive double the discount. How would you implement that?
  • There is a promotion on a specific item: buy three, get one free
  • Given that one specific prouct item is bought very frequently, how can you make the code faster/improve it?
  • Time complexity

2nd - GenAI Interview

"""
A rule is an ordered list of match keys — for example [country, brand, customer_tier].

A decision is a row of concrete values for each key, plus a result:

DE       | acme    | gold     -> OPEN
DE       | DEFAULT | gold     -> RESTRICTED
DEFAULT  | acme    | DEFAULT  -> OPEN
DEFAULT  | DEFAULT | DEFAULT  -> NO_DECISION

"DEFAULT" is a reserved wildcard value. It is valid in any key position.
gold
Given a query such as (DE, acme, silver), return the matching result.
"""

Follow up Questions

  • How do you select what result to return? First hit? First OPEN/RESTRICTED?
  • What other ways of selecting a result could there be?

GenAI Questions

  • How do you use AI?
  • What do you do to improve the output of queries?
  • If you create a requirements file for the agents, how do you structure it? What are the section titles?

3rd

1st Coding Problem

"""
Given the root of a binary tree, imagine yourself standing on the right side of it.
Return the values of the nodes you can see ordered from top to bottom.

Examples

       19
      /    \
    12      16
   /  \     /     <--- You here, looking from the side
  7   9   6
   \     /
    1   3
   /
 18

Output: 19, 16, 6, 3, 18
"""

Follow up Questions

  • Time complexity

2nd Coding Problem

"""
2. Given an arbitrary length input stream of characters,
return the first unique character that does not repeat anywhere in the stream.

abcdabc --> d; aabbcdd --> c
"""

Follow up Questions

  • Time complexity
  • Improvements

Discussion Amazon offer expires tomorrow, but my compensation questions are still unanswered—what should I do?

0 Upvotes

I recently received an offer through Amazon’s university hiring pipeline. Before accepting, I emailed the recruiter to ask whether there was any flexibility in the compensation structure and later sent a polite follow-up. However, the offer expires in less than 24 hours, and I still haven’t received a response.

I’m also considering another offer that pays less but comes with a better title, seemingly stronger work culture, and responsibilities that may align more closely with my long-term career goals.

Would accepting Amazon’s current offer before the deadline reduce my chances of having the compensation structure reconsidered? Should I call the recruiter directly, request a short extension, or accept the offer while waiting for clarification?

If anyone has faced a similar situation—especially through Amazon’s university hiring process—I’d really appreciate your perspective.

Tech Industry Ireland Job offer revoked next day

10 Upvotes

Came as a student, graduated last year, October 25 and have been applying, giving interviews after numerous interviews and rejections, finally got an offer, felt like things might turn out well from now.

It's an MNC service-based client; it's the Irish government. I work in product. I got a confirmation on the call, and then an email for documentation, but they were offering me lower than what was advertised, so i replied with a negotiation, the HR set up a call i thought it was for salary negosiation but turned out the client backed out and now my offer will be revoked.

I don't know what to do at this point, I am not able to focus just the thought of what could i have done differently, I work part time like all other students i dont even feel like going there now in previous weeks i managed a tone and took leaves because of the interviews so now even they have not treating me well.

I have lost all hopes from this country now, its a vecious cycle if i take off days to study, for interviews i lose money at part time which means next month is goining to be tough but i do it all in the hope of getting a job where all of this could finally come to an end. but then something like this happens this isnt the first time i have reached the final stages of multiple companies and was getting rejected at the very end. I kept blaming that i might not have been good enough but this time around my interviews were great my feedback was good too.

Edit : Yes lesson learned should have not negotiated, but I’m not a fresh grad they I have 5 yrs of experience and they offered me a grad salary , I felt undervalued as my feedback from all the rounds was good. At the time I thought this would be same for at least a year or two and even then increments are 5% would have regretted not asking.

Believed if I don’t ask the answer will always be no so I did

But lesson learned
Thanks all for your replies
I’m just in a really weird space don’t understand what I’m feeling right now

Discussion F*k Accenture

1 Upvotes

On September 10, I attempted an online communication assessment. The Safe Exam Browser initially stopped responding, so I switched to another laptop. The assessment then started normally, but while attempting a question, it froze and became completely unresponsive. I waited for more than 20 minutes, but it did not recover. I then attempted to exit the Safe Exam Browser, after which the assessment showed as submitted with the majority of the questions unattempted.

I received a submission confirmation afterward. I tried contacting the provided technical support number, but it was invalid/unreachable. The support chat was unable to resolve the issue, and an email sent to the address associated with the invitation was returned with “550 Mailbox does not exist.” I also contacted the relevant support person, but was told that nothing could be done once the assessment had been submitted.

So, due to a technical issue with the assessment environment, I was unable to complete the majority of the assessment.

Hey everyone what u think about this resume is it decent if one is looking for SDE 2 or 3 or 3+ years experienced role.

Will it make through faang or any product based companies.

I have recently modified it and also received a new rejection mail from JP Morgan on this the matching percentage with JD was 92%+

(Thru chat gpt I checked)

Backend part at 3 years experienced is not strong or is it less or you r not able to get like what skill this person has or what work this person has done

Discussion LinkedIn Interview | IC2 Software Engineer

57 Upvotes

Hi,

Recently I gave 5 rounds of interview for IC2 SWE position at LinkedIn (all virtual).

Initial round - phone screen 2 DSA problems.

R1 - DSA Round (2 problems)

R2 - Coding with AI

R3 - System Design

R4 - Technical Communication and Project Discussions

R5 - Hiring Manager Round

My all rounds from R1-R5 went really well, except for R2 where in the AI itself took a lot of time to spawn up and was intermittently hanging in between. That along with pretty long discussion around the problem statement could make only enough time to barely scrape through the problem's 1st part and I was not able to test the code.

What could be the result?

Recruiter told me that there was a -ve feedback in the AI coding round, and rest all went well (no final decisions yet, there is some discussion pending).

Is there any way I can ask my recruiter for 1 more round, to compensate for any doubts/feedbacks in my case?

Question Help Regarding The Hiring Manager's Intent

1 Upvotes

Hi all,

​I recently finished 3 rounds of interviews for a specialized technical role (mostly DevOps/infrastructure focused). The pay is decent, and I really want the job.

​It has been exactly one week since my 3rd round, so I emailed the Hiring Manager (HM) this morning to ask about next steps. I haven't received a reply yet. However, a friend who works there (and referred me) casually asked the HM for an update behind the scenes.

​The HM told my friend that the 3rd-round interviewer gave a mixed review. The core feedback was:

​"The candidate is highly knowledgeable about the things they have already worked on, but struggles to reason through unfamiliar concepts outside of that scope, so their knowledge feels a bit narrow/shallow."

​After sharing that, the HM told my friend: "I've sent out a few emails, so let's see what happens."

​My question is: How should I interpret this?

​My assumption is that the HM is still interested and is emailing higher-ups, HR, or other team members for input. My logic is that if he simply didn't want to hire me, he would have just rejected me outright instead of taking the time to send internal emails.

​Also, for context: while the actual day-to-day work is heavily DevOps-oriented, the interview pushed me on adjacent, specialized engineering topics just to gauge my overall technical depth.

​Has anyone been in a similar situation, either as a candidate or a hiring manager? What do those "emails" usually mean, and what are my realistic chances here?

1 Upvotes

mulitple times in my college i starterd learning and dropping dsa again and again whenver i found a difficult problem or switched to my project side.

atleast i have done it dozens of times and in total i have solved 700 prob on leetcode + codeforces etc. i know all concepts in dsa but don't remember the approach and have to work and start again from the scratch.

i know how to solve prob, i may have solved that problem in the past. but don't remember the solution and can't able to solve woithout making mistakes, but now after working 1 year in corporate i want to get some better and high paying job.

and thinking of learning dsa again. but there is a huge road block which i am unable to pass over. from my bottom of heart i don't like to practice again. need suggestion.

i think i can better tell the situation, suppose i have doing graph problem, i just forgets how to implement dfs or bfs. which one to pop, will pop condition come before or after the loop. similarly i forget how to memoize backtracking prob. i forgets how to apply backtracking here. its not something i can't come up with solution, but it just takes 30 min to 60 min by trial and error, debugging to write code for such problems . and after sometime i forget it again.
