Currently I am seeking a new job due to being laid off and a lot of the interviews I have I am gated by my lack of leetcode proficiency. I can sometimes understand the high level solutions but I always have trouble implementing them perfectly and am always missing something that handles an important edge case or optimizes the solution. As a result my initial solution always breaks. Each time I do a new problem I rarely ever solve it without looking at the solution eventually. Has anyone else been in this situation? And if so how did you get better? Doing 1-2 problems a day and trying to understand the solutions but its frying my brain.

Hey everyone,

I finished Day 29 today. Even with Chhath Puja festivities keeping me busy and tired, I sat down and cleared seven foundational array problems in a quick session.

Looking back at when I first started, even basic array manipulation used to trip me up. Today, the core patterns clicked right away, allowing me to breeze through the standard logic and focus on clean implementation:

1. Left Rotate an Array by One Place: Saved the first element, shifted elements left in a single pass, and placed the saved element at the end.

2. Left Rotate an Array by D Places: Applied the three-step reversal algorithm to rotate in-place in O(n) time and O(1) space.

3. Move Zeros to End: Used a two-pointer swap approach to shift non-zero elements forward while keeping relative order intact.

4. Linear Search & Maximum Consecutive Ones: Practiced clean single-pass tracking and boundary resets.

5. Find the Union of Two Sorted Arrays: Used two pointers to merge elements in sorted order while skipping duplicates.

6. Find Missing Number in an Array: Used the expected sum formula (and XOR properties) to find the missing value in O(n) time without extra space.

I still need to circle back for a dedicated Graph revision, but seeing how much easier foundational problem-solving feels now is great motivation.

See you guys tomorrow for Day 28!

Hi everyone,

Has anyone recently completed the final interview loop for an L5 Embedded Software Engineer role at Amazon Leo?

I'm preparing for my final loop and would really appreciate hearing about your experiences.

I'm particularly interested in:

1. Interview structure: Is it 3 coding rounds and 1 system design round, or is the structure different?

2. Exact coding questions: What specific coding problems were you asked? Were they LeetCode-style DSA or more embedded C/C++ focused?

3. System design: What exact system design problem or scenario were you asked to solve? Was it high-level system design or embedded/low-level design?

4. Embedded technical questions: What specific questions came up around RTOS, concurrency, memory management, interrupts, device drivers, or debugging?

5. Leadership Principles: Which LP questions were asked, and how were they distributed across the rounds?

If you remember the exact questions or even similar examples, that would be extremely helpful for preparation.

I'm especially interested in recent L5 Amazon Leo/Kuiper interview experiences rather than general Amazon SDE interviews.

Thanks in advance for any insights!

Any one who have been through Bloomberg system design interview for 2027 round, can u share me the question that u have been asked?

Currently a junior CS at Non-target(T80 school) really need some advice on how to get a proc from Meta would really appreciate any tips!

I have an upcoming interview with SaaS Labs for an SDE-2 position. I've received an email for the initial screening round scheduled for Monday. I wanted to know if anyone has recently interviewed with SaaS Labs for an SDE-2 role. It would be really helpful if you could share: How many rounds are there in the overall interview process? What kind of questions are asked in the screening round? What topics should I focus on for preparation? Are there separate DSA, machine coding, system design, and managerial rounds? How difficult is the overall interview process? Any recent interview experiences or preparation tips would be greatly appreciated. Thanks in advance!

Hi
I m looking for leetcode interview study buddy
,who are doing company specific leetcode problems and are not beginners
We can discuss daily company specific problems by screen sharing or voice call

I applied for the Software Development Engineer I, Amazon University Talent role (Job ID: 10454438) a week ago. Has anyone received an OA link for this position yet?

Hello,

I want to ask if there is sb who gave the DB interview and if it could share what the interview expected them to do? Was it talking to the AI to write the whole code, should you also build the test cases together with the AI? What seemed to be the expectations from the interviewer? Did it have more follow-ups that needed to be coded with the help of AI?

Basically the AI companies' coding interviews each round question is composed of multiple parts. It is quite exhausted to answer each part with bug free. Curious how you guys navigate through the multiple parts? Thanks.

Gave the oa on 2 november after getting shortlisted off campus

Has anyone else given the oa and got any callback?

Hi everyone!

I'm a Lead Software Engineer with around 9 years of experience in .NET, React, and full-stack development. I'm looking to transition into Google or another FAANG company, ideally into an AI Engineer / AI Architect / Software Engineer role.Im naive at DSA and design.

I'm willing to invest in a good course or structured programme, but I don't want to spend money on courses that just sell dreams of high packages.

I'd love recommendations from people who have actually cracked Google, Microsoft, Amazon, or similar companies.

A few questions:

Which courses or programmes genuinely helped you crack FAANG interviews?

Is Educative, Udemy, Interview Kickstart, Scaler, or any other programme worth the investment?

Are there programmes with genuine placement assistance or referrals?

For someone with 9 years of experience, what should I focus on: DSA, System Design, LLD, AI Engineering, or something else?

Did any course directly contribute to getting your offer, or were free resources sufficient?

I'd especially appreciate advice from people who have personally received FAANG offers, rather than course promoters.

Thanks in advance! 🙏

First 5 min: repeat the problem back, ask about input size and edge cases.
Say the brute force and its complexity before optimising, even if you know the trick.
Before coding, say the plan in two lines.
While coding, narrate decisions, not keystrokes.
Before saying "done", walk one example through your code.

Practising this alone feels silly. Recording yourself or doing it with one friend fixes that fast. What habit helped you most?

Hi, has anyone taken the OA for this role ? Does it have leetcode questions ? My recruiter sent me a link to help me prepare for the OA and it was a link to amazons leetcode questions but I have seen people say they got no leetcode questions so I’m just wondering if she sent it by mistake or it’s a template everyone gets. If you received a OA for this role , did your recruiter include a link to leetcode practice questions in the email? Thanks a lot .

How to approach DSA before interviews in 1-2 month ?

Do they consider the time it took for you to complete each problem? Do you give partial credits for passing some of the test cases?

Hi! I was wondering if anyone had gone through it and had any insights into the range of topics they ask about, the difficulty, etc. Please let me know, thank you!

Hi guys, I am having upcoming 2 technical interview rounds for Production Systems Engineer Intern role at Meta. I am wondering what can be covered besides leetcode?

Thank you!

Which course would you recommend for learning system design thoroughly and preparing for FAANG interviews targeting 2+ years of experience? Would love to hear what worked for you.

Does anyone know any good leetcode reel creators? Recently came across this guy's shorts (https://www.youtube.com/shorts/pk1R2JKvRQU) and am looking for more stuff like it so I can rot and learn at the same time 💀

Hi

Do I leetcode prep or no

Hey guys
I just finished Amazon SDE intern summer 27 OA.
Results:
15/15 in dsa (20 min)
5/6 in AI base coding

I know I fcked up in 2nd question. Any chances of getting Interview?
any comment help, thanks

Anyone recently inteview for a intergration or deployment engineer position at Figure AI?

How was the experience and what was the process like?

Howdy 👋
Has anyone recently gotten an AI assisted coding round for L5 software engineer role? Recruiter said it would be like Leetcode only but with Gemini. But Reddit says it could be debugging into a massive repo or open ended coding problem similar to system design round.

Please share your experience. I will post mine once my round is complete to help out the community and fellow dreamers. Thanks!

Hey everyone,

I finished Day 30 today. After wrapping up core data structures and algorithms like Recursion, DP, Graphs, Trees, and Linked Lists, I decided to circle back to Arrays. I want to build sharper intuition for constructive algorithms and mathematical patterns without relying on rigid templates.

I eased in with four foundational array problems today:

1. Largest Element in an Array: Tracked the running maximum in a single O(n) pass without extra space.

2. Second Largest Element Without Sorting: Maintained both largest and second-largest variables simultaneously in one linear scan to avoid O(n log n) sorting overhead.

3. Check if Array is Sorted: Verified adjacent element ordering in a single pass, including rotated sorted edge cases.

4. Remove Duplicates from Sorted Array: Used a two-pointer approach to overwrite duplicates in-place in O(n) time and O(1) space.

These problems are straightforward, but locking down clean, optimal single-pass habits sets a strong base before moving into trickier constructive array challenges.

See you guys tomorrow for Day 29!
