Where do you guys find some good startups to apply for?

I have been using LinkedIn but looking for other websites specifically for startups as most of the jobs on LinkedIn are either reposts or already have thousands of applicants. And other than the industry, funding and product what are some of the other things you guys look for when considering a startup?

Would love to hear some positive and negative experiences too for those who want to share.

I keep getting super close to landing FAANG.

It’s honestly exhausting at this point. Multiple onsites, a couple of them going really well until the final round or one random coding or system design segment where I just falter. It’s so unfortunate how I don’t do well under pressure, i make these tiny stupid mistakes and it snowballs. My private practice feels solid, but the moment it’s real and observed, everything shifts. Yesterday i posted something similar on teamblind asking for advice and someone just hit me with “eff off, SWE is dead.” that one stung more than it should have. Now i’m sitting here frustrated and wondering if it’s even worth it anymore or if i’m just not built for this market.

I don’t believe coding is disappearing or that AI is taking over software development. Do you ?

I don’t believe coding is disappearing or that AI is taking over software development. Tools like “vibe coding” are useful, but they don’t replace real problem-solving skills. Many of these tools work best in the hands of experienced developers rather than complete beginners.

The hype around no-code or vibe-based development seems to be fading, especially when we look at actual revenue and long-term sustainability. At the same time, the industry is clearly shifting toward generative AI, which still requires strong technical understanding to use effectively.

In my opinion, the demand for skilled developers is likely to increase, not decrease. However, developers will need to adapt by learning new tools, including AI-assisted coding, and expanding their skill sets rather than relying only on traditional approaches

I don’t really believe in raw LeetCode grinding anymore

I kind of stopped caring about solving every LeetCode problem fully on my own.

I have been trying Claude with problems, and honestly it feels way more efficient. I would rather spend my time understanding the concept, the pattern, and how to use AI well instead of sitting there stuck for a long time just to say I did it alone.

At this point, learning how to think with AI feels more valuable to me.

No more need for an API

No more need for an API

I built a system that uses ChatGPT without APIs + compares it with local LLMs (looking for feedback)

I’ve been experimenting with reducing dependency on AI APIs and wanted to share what I built + get some honest feedback.

Project 1: Freeloader Trainee

Repo: https://github.com/manan41410352-max/freeloader_trainee

Instead of calling OpenAI APIs, this system:

  • Reads responses directly from ChatGPT running in the browser
  • Captures them in real-time
  • Sends them into a local pipeline
  • Compares them with a local model (currently LLaMA-based)
  • Stores both outputs for training / evaluation

So basically:

  • ChatGPT acts like a teacher model
  • Local model acts like a student

The goal is to improve local models without paying for API usage.

Project 2: Ticket System Without APIs

Repo: https://github.com/manan41410352-max/ticket

This is more of a use case built on top of the idea.

Instead of sending support queries to APIs:

  • It routes queries between:
    • ChatGPT (via browser extraction)
    • Local models
  • Compares responses
  • Can later support multiple models

So it becomes more like a multi-model routing system rather than a single API dependency.

Why I built this

Most AI apps right now feel like:
“input → API → output”

Which means:

  • You don’t control the system
  • Costs scale quickly
  • You’re dependent on external providers

I wanted to explore:

  • Can we reduce or bypass API dependency?
  • Can we use strong models to improve local ones?
  • Can we design systems where models are interchangeable?

Things I’m unsure about

  • How scalable is this approach long-term?
  • Any better alternatives to browser-based extraction?
  • Is this direction even worth pursuing vs just using APIs?
  • Any obvious flaws (technical or conceptual)?

I know this is a bit unconventional / hacky, so I’d really appreciate honest criticism.

Not trying to sell anything — just exploring ideas.

Solved 150+ Leetcode problems but still feel stuck🤧- how do i improve ?

Hey everyone, I’ve been practicing LeetCode for a while and have solved around 150+ problems.The thing is, I don’t feel as confident as I expected. Sometimes I solve problems, but when I face new ones, I still get stuck on how to even start.It feels like I’m just solving questions, but not really improving my thinking.I’m not sure if I should change the way I practice or if this is normal at this stage.If you’ve been through this phase, how did you overcome it?

Tekion Interview - Design a Policy Engine | LLD

Company: Tekion
Round: Technical (DSA)
Date: 4th April 2026
Type: Hiring Drive
Difficulty: Medium-Hard

Context

Attended a Tekion hiring drive on 4th April 2026. This was the DSA/Problem solving round. The interviewer gave a real-world design problem around a policy engine — something very relevant to Tekion's domain (automotive retail / DMS platform where configurable business rules are common).

The Question

Design a Policy Engine. We define a list of policies where each policy contains a condition expression (combination of AND/OR operators over field comparisons). Given a policy ID and a data object, return ALLOWED or DENY.

What was asked specifically:

  1. Design the data model for:
    • Policy (id, condition tree)
    • EvaluationRequest (policyId, data)
    • EvaluationResponse (policyId, decision)
  2. Write code for the policy engine that evaluates the conditions and returns ALLOWED/DENY.

Sample Policy given by interviewer

P1: {
  (creditScore >= 720 AND accountStatus == "Active") OR (receivableDays < 30)
}

Sample Data

{
  "creditScore": "750",
  "accountStatus": "Active",
  "receivableDays": "45",
  "annualRevenue": "600000",
  "yearsInBusiness": "5"
}

Based on policy ID and the data object, the engine should return ALLOWED or DENY.

Hope this helps anyone prepping for Tekion interviews or LLD rounds in general!

Neetcode pro lifetime access?

I’m already using LeetCode Premium and find the company-tagged questions very helpful. However, I don’t use it much right now since I’m not planning to change jobs, but I still want to have access in the future.

I have an education budget from my employer that expires each year, so I’d like to use it. I noticed that NeetCode Pro offers a lifetime access plan—how does it compare to LeetCode? It also seems to have company-tagged questions.

Stripe OA (Backend)

Just completed my Stripe hackerrank.. and.. damn. The question wasn’t even hard, and I had my code near-perfect. I eventually ran out of time fumbling around with stdin and stdout, and some very minor bugs (not even to do with the core logic).

What’s the likelihood of me getting through? :(

DSA Sheet for Job Switch

Hi everyone,

I’m currently working at a startup and have around 7 months of experience. Before getting this job, I solved close to 1000 problems on LeetCode during my preparation phase.

Now I’m planning to switch and want to get back into DSA prep. However, I don’t want to redo everything from scratch again.

What would be the most effective DSA sheet or resource in 2026 for revision and interview-focused preparation? Looking for something concise but comprehensive enough to cover important patterns.

Would really appreciate your suggestions.

Struggling to get back to DSA

Hi, I’m a full stack developer working in a startup. The startup culture here feels very tough, so I’m trying to move to a product-based company.

For that, I started learning DSA in Aug 2025, but due to work pressure I had to stop in Dec 2025. Now my project is finished and I have some free time after work.

But I’m feeling very unmotivated and not really interested to start again.

One reason is all this AI hype it feels like it’s growing and I’m not sure how it will affect things. Another reason is earlier on Reddit I used to see a lot of posts where people shared their interview experiences, how they learned DSA and cracked interviews. That used to motivate me a lot.

But in the last 2 months, those kinds of posts feel very rare compared to before.

Is anyone else feeling like this?
Does anyone have any motivation or positive news to share?

LeetCode Weekly Contest 496 - How I solved them

LeetCode Weekly Contest 496 - How I solved them

Overall a 6/10 difficulty contest I'd say.

EDIT: I wrote the above cause a lot of people ask for how hard the contests are, I'm just giving my opinion for that is all

Q1: Kind of an implementation battle. I recommend just making functions like mirror(char) to make it easy. Also a good trick to avoid duplicates is just to hash them like always put the smaller letter first, and store tuples of ones we have considered, in a set. so (a, z) goes into a set, and when we get to (z, a) it gets hashed to (a, z) and de-duped.

Q2: Since N is large we cannot enumerate it. Instead, observe the maximum of a single factor can be n^1/3. Now just enumerate pairs of these options which gives us n^2/3 complexity. Track how many numbers get at least two occurrences.

Q3: If N is odd it is easy, we make the indices 1, 3, 5, ... peaks.

If it is even we run into some tricky cases...

#    1 | (2) 3 (4) 5 (6) 7 | 8
#    1 | 2 (3) 4 (5) 6 (7) | 8
#    1 | (2) 3 (4) 5 6 (7) | 8
#    1 | (2) 3 4 (5) 6 (7) | 8

Numbers inside the () are peaks. We can basically put a single gap of 2 in multiple places. But note we cannot put it at i=1 or i=n-2

To find the best answer, I used a prefix + suffix to track the scores on the left and right regions, and enumerated the possible locations for the gap. Lots of edge cases.

Q4: dp(index, peaksLeft, didTakeFirst) is n x k x 2 complexity. A knapsack DP.

Note that this is too much in python so you can either attempt a cursed bottom-up solution that only uses K memory, but it's annoying since we have 2 dp arrays and need to preserve the last 2 layers for the recurrence. Or you can just use C++.

We could also observe that k is at most n/2 but even then it's sus in python.
