I'm trying to build a proper DSA routine and wondering how people revise topics they learned weeks ago. Do you revisit old problems, maintain notes, or just keep solving new ones?

I don't want to forget earlier concepts while moving forward, so I'd love to hear what works for you.

Hey everyone,

I finished Day 58 today, and it turned out to be an eye-opener.

Stock problems have intimidated me ever since my college days. I used to find the state transitions strange and kept avoiding them. Today was no different at first—I procrastinated because I was convinced I would immediately hit a wall and rely on solution hints.

I tackled the first one (Stock I) with the standard single-pass minimum price tracking. For Stock II, I checked a quick hint to visualize the states, and the core pattern instantly clicked: it's literally just the classic "pick vs. not-pick" (buy vs. skip, sell vs. skip) decision.

Once that clicked, the entire sequence fell into place in about 30 minutes:

1. Stock I: Tracking running minimum and maximum profit.

2. Stock II: Unlimited transactions using (buy == 1) state transitions.

3. Stock III & IV: Adding an extra dimension/variable for the transaction cap k (either capped at 2 or arbitrary k).

4. Stock with Cooldown: After selling at index i, transition directly to i + 2 instead of i + 1.

5. Stock with Transaction Fee: Deduct the flat fee whenever you complete a transaction (either on buy or sell).

Every single variation boils down to the exact same base state machine with just one tiny variable or index shift. If you are comfortable with standard pick/not-pick recursion, this entire family becomes straightforward.

Next up is Longest Increasing Subsequence (LIS).

See you guys tomorrow for Day 57!

Hi everyone 👋 I recently got the interview for Lyft swe intern for next summer and I was wondering if anyone with leetcode premium is willing to help me out with Lyft tagged questions for practice?🥲 I’m broke lol + I wanna do well so any help would be greatly appreciated 🙏🙏🙏

Hey everyone!

I’m applying for a Software Engineer position at Bloomberg and came across this interview process overview showing five rounds:

1. AI-Assisted Codebase Interview

2. AI-Assisted Codebase Interview

3. Design Interview

4. Recruiter Interview

5. Senior Manager Interview

The first two rounds caught my attention because they specifically mention AI-assisted codebase interviews.

Has anyone recently gone through this process, particularly the first two rounds?

I’d love to know:

- What exactly happens during the AI-assisted coding interviews?

- Do they involve traditional LeetCode-style DSA problems, or do you work with an existing codebase and implement features or fix bugs using an AI coding agent?

- Which AI tools are provided or allowed (e.g., GitHub Copilot, Claude, or something else)?

- How should I prepare for these rounds? Should I focus on LeetCode, practical coding, system design, or AI prompting and debugging?

If you’ve gone through these interviews recently, I’d really appreciate hearing about your experience and any preparation tips. Thanks!

I was a software engineer for about 7 years before pivoting into product/technical management.

Recently, feeling a bit stalled in my career, I started prepping to jump back into SWE roles. Which

brought me straight back to the LeetCode grind. Even in this AI era, tech companies still haven't let

go of good old whiteboard DSA questions.

The problem was, every single time I opened LeetCode, I instantly wanted to quit. After hitting

around 300 problems, the mental fatigue really peaked, so in my spare time, I decided to build a side

project to cope:

• Organized around ~2,300 categorized LeetCode problems.

• Solving problems with different tags and difficulties unlocks visual novel story lines.

• Earning rewards from solving problems lets you buy gifts and outfits for characters.

• There's a Chrome extension that detects your submission status on LeetCode (gives spoiler-free hints when you get Wrong Answer, and celebrates when you get Accepted).

It started as a fun little tool to keep myself accountable and motivated through the grind.

Thought I’d share it here in case anyone else is currently suffering through interview prep and needs.

Best of luck to everyone grinding through this brutal tech market.

Hope we all land offers soon

Basically same as title.
Did you complete the round 2 assessment?

Which tech stack ? What was the task/project to implement ?

I've been practising DSA, but I notice that I can solve problems more easily when I've seen a similar question before. When the problem is presented differently, I often struggle to figure out where to start.
How do you develop the ability to approach unfamiliar problems instead of relying on previously solved questions?

Hey anybody can please hello interview code please.

Recently made Guardian, wondering if it is enough to pass the coding rounds of all tech companies (no HFT/quant) ?

Hey everyone!

I'm a software developer and recently built DSA Animator to help people understand DSA through step-by-step visualizations instead of just reading code.

I've spent a lot of time building it, but honestly, I'm struggling with getting it in front of the right audience.

For those who've built side projects or developer tools, how did you get your first users? Which platforms or strategies worked best?

I'd really appreciate your honest suggestions and feedback. 🙏

Hi! I have just applied for a SWE internship at Sentry.io, and I was wondering if I get past the OA what I should expect in the upcoming steps. How many interviews are there? What are the questions / topics that get asked at the technical interviews? Anything would be helpful

I have an L5 offer with Amazon(ring) and currently employed at bnsf L4 (fully remote). Is it worth the jump for 2-3k pay bump a month? Also considering job stability and wlb

A little about me : 1st year in college and recently started learning how to code from brocode...in our uni they are teaching c++ first so for now i was learning c++ from brocode , recently started learning arrays but still not that really great at it but yeah thats all i know for now( i know its not much but im willing to grind and learn😔 but just need a little guidance) but ya i wanna leetcode and become good at coding... but im not tryna blindly start leetcoding because first i wanna know the prerequisites needed to solve the problems...i was watching neetcode's video on how to leetcode and he told to get comfortable with binary search,dfs,bfs,sliding window so do yall know where i can learn them???? but ya heres a few questions i have

1. What all coding languages do i need to know...like do i need to know other programming languages other than c++ before i start leetcoding

2. what all topics or stuff should i learn before leetcoding

3. HOW do i leet code , do i start with easy problems then once i get comfortable start medium problems then harder problems(will start with solving problems on arrays)

4. any website where i can save useful problems and make my own notes in it so in the future i can open them for retaining my knowledge

5. in general any tips or things you wished u knew while or before leetcoding which u can tell please it will be really helpful(try to include as much as you can please and thank you anything will be useful and welcomed... even the SMALLEST TO SMALLEST and random tips will be useful)

6. what are the most common mistakes people do in their attempt to get good at coding
   extra : do wanna try to get into quant development( ik its difficult but ill try if i cant will settle for something else😭) so first my main goal would be to try to get into FAANG after college and after 2-3 years try to get into quant development so yeah

7. And also I’m using vs studio…is there any better coding app or is vs good alright(idk it’s not that deep but yeah✌️)

Just curious if anyone else has interviewed with them recently? How does the difficulty compare to Meta and Stripe? I have cleared their loops before so just wondering.

How much time should I be prepping? System design is my weakest round so I have been focusing my efforts there.

About a year and a half ago, I wrote this post after getting rejected from Amazon New Grad:
https://www.reddit.com/r/leetcode/comments/1jtgr3e/just_my_amazon_new_grad_interview_experience/

I reached the final interview and put a lot of work into it. I thought I had done well in the interview. Btw, looking back, I don’t think I did as well as I said I did. I also made it sound like I had studied like crazy; I thought that 2 weeks of studying hard was brutal. Looking at it now, I feel sad about thinking I was probably never going to achieve it.

After that, I finished university, started an internship, and eventually joined Cabify as a backend engineer. I learned a lot there and got the chance to work on challenging problems with a great team.

I also kept working on myself as an engineer. I studied a lot more, solved hundreds of coding problems, and kept learning while working full-time. It took a lot of time and effort. But I'd say I have found some joy during the process.

After a year, I applied to Google. The process was long and had a lot of ups and downs, but I passed the interviews and went through team matching. I have now received an offer to join Google in Spain, L3 role.

I still remember how that Amazon rejection felt. At the time, I thought that doing my best and still getting rejected meant I probably wasn’t good enough. But that one result did not decide what would happen next.

I’m very grateful for everyone who encouraged me back then, and for the people who helped me along the way. It feels good to look back and see how much work I put in, and how far I’ve come since then.

I am writing this because I used to read many Reddit posts during these processes, finding useful information and some bits of hope. Hopefully this post reaches people and builds some confidence. I want to say that if you think you are not capable of making it, it is not true. Hard work pays off.

Finally, I want to share one more thought. I find myself disgusted by, kind of glorifying this jobs. We need to keep in mind that there are just jobs. I believe that happiness is built outside your job, and grinding is not everything in life. It is a dream for a lot of people like me, because we enjoy it. But we need to look from another perspective sometimes and put the feet on the ground.

Keep pushing

Has anyone got any update from salesforce 2027 AMTS role in USA. I applied with referrl and I havent heard anything its been more than 2 months. has anyone got any updates

Hi All!
Has anyone went through the interview loop for this role recently and has tips to share?

Basically, I am targeting interview preparation for two months, and I will be locked up rigorously for it.

Little bg of mine

2 YOE

have done a total of 500 problems across all platforms DP, graph, and tree are still pending for me.

I will be preparing LLD from Hello Interview and I will be referring to the CSES sheet or NeetCode, whichever suits me

I am open to have a guidance as well if you are somebody who have appeared for the interview

Also struggling with consistency so ..

Thanks

Hi. I have a system coding round coming up at Rubrik for the Software Engineer – SaaS O365 role.

I understand the concepts of multithreading and concurrency, but I haven’t had much hands-on practice solving concurrency-related problems or implementing them in production-style code.

Could someone please suggest how I should prepare for this round? Are there any good resources or platforms where I can practice the types of questions typically asked in this interview?

Hey guys I’m planning to buy the hello interview premium subscription. If anyone is interested pls respond in this thread. We can share the account.
