Saw a man working in Croma today, using a laptop with a broken screen.
Croma ..the store that sells laptops.
Just think about it.
Your employee is selling new laptops while struggling on a broken one.
That cracked screen can hurt the eyes over time.
It’s not a big thing for a company to fix, but it means a lot for the person using it.
Take care of your people. They deserve better.

I wonder who the engineers behind adult sites are. Some of them get more traffic than YouTube & Netflix. Their software, cloud, and infra teams must be next-level. Never see anyone mention they work there… where are you all hiding? 👀

My relative’s son got laid off from Amazon today. He used to brag a lot about his salary and job ... always acting like he was doing something extraordinary. Because of that, all of us cousins would often get compared to him and scolded to “be like him.”
Honestly, I never really liked his attitude. He wasn’t very knowledgeable and just happened to get lucky during the big hiring boom. But despite all that, I genuinely feel bad for him and his family . he has a three-year-old child now, and this must be really tough on them.
I hope he’s able to find another job soon, though it might be challenging since he never focused on improving his skills or learning DSA. He thought his job was secure and didn’t need to prepare for the future. It’s a tough reminder that no job is truly stable these days.

Twitter isn’t social media. It’s a battlefield.
Open the app:
— 18 y/o building a startup
— Someone just made $100K
— Another grinding in silence at midnight
It’s not Insta’s dopamine trap.
It’s a mirror.

My sister didn’t even know HTML but got into a hackathon where they had to code using AI.
Only one in her group knew basic web dev.
They still landed 3rd place out of 800 and an internship all in there first year.

Cleared my Technical Round - 1 🥳🥳
The interview experience was a mix of fun and learning moments 😅
Introduction – I kept it short, and the interviewer even joked, “Bass hogaya"
name & degree is enough bro for this round 🥲
Questions I faced:
> Reverse a string (felt funny since I had just solved a backtracking question before this round 😅)
> Postfix ➝ Prefix conversion (took me a few minutes to think but solved it using a stack ..never thought this would come in an interview )
> OOPs concepts – discussed the 4 pillars in depth & played around with the super keyword
> Collection Framework – how it works and how the design is structured
Overall, it went smoothly ✅ and I really enjoyed the balance of basics + advanced concepts.
On to the next round 🚀

Top 10 Coding Concepts You Must Master Before Any Interview
1. Time & Space Complexity
Learn Big-O notation to analyze how efficient your code is.
2. Recursion
Understand base and recursive cases.
Practice problems like factorial, Fibonacci, and tree traversal.
3. Sorting Algorithms
Know how Bubble, Merge, Quick, and Insertion Sort work.
Focus on time complexities and when to use each.
4. Two Pointers
Ideal for array and string problems such as palindrome checks, duplicates, and pair sums.
5. Sliding Window
Essential for subarray problems like maximum sum or longest substring.
6. Binary Search
A must for sorted data problems.
Also useful for solving range-based or search space problems.
7. Hashing
Use hash maps to store counts, frequencies, or index positions.
Common in anagram, duplicate, and pattern problems.
8. Greedy Algorithms
Make the locally optimal choice at each step.
Great for interval scheduling, coin change, and activity selection problems.
9. Dynamic Programming
Break problems into smaller subproblems.
Master memoization, tabulation, and common patterns like Fibonacci, Knapsack, and LIS.
10. Graphs
Understand DFS, BFS, cycle detection, and shortest path algorithms (e.g., Dijkstra’s).
Practice problems on connected components and topological sorting.
Tip: Focus on understanding patterns not just memorizing solutions.
❤️Save this list and keep refining your problem-solving foundations.

I used to be upset with @kirat_tw during Cohort 3.
He never completed any projects for us.
He just kept saying “Do it yourself.”
Back then, I thought he wasn’t helping enough.
Now I realize…
He was helping the right way.
Because real learning doesn’t come from someone building for you.
It comes when you struggle, debug, and figure it out yourself.
Kirat didn’t hand me answers.
He gave me direction.
And that changed everything.
If someone refuses to spoon-feed you
They might be the best teacher you’ll ever have.

✅ Interview with the Head of Software Development went well!
We discussed:
> My DSA journey and how many questions I’ve solved so far
> My projects especially the approach I took before building them
> Whether I can code without AI assistance
> And importantly, when and how to use AI effectively
> Great conversation overall feeling positive about this round! 🙌

No one talks enough about the LUCK in job interviews.
You can prep for months. Perfect resume. Impeccable answers.
But if the interviewer had a bad day,
If they silently preferred someone from their alma mater,
If they already made up their mind before your slot…
You lose.
It’s not always about talent.
Not always about effort.
Sometimes it's about timing, bias, vibes, or pure randomness.
You didn’t fail.
You just didn’t fit that room at that moment.
Don't let rejection define your worth.
Keep showing up luck finds those who persist.

If men can be shirtless without it being sexual, women should be able to as well. Let’s normalize equality, not shame. Bodies aren’t the problem conditioning is.
Okay? I agree.
Now, if a man makes a video being shirtless, can you do it too to prove your point that it’s normal?
If you can, it will be an inspiration for future generations for sure. You should start with yourself first.

Complete Coding Interview Roadmap – What You MUST Know
Whether you're preparing for FAANG or startups, here's everything you need to crack coding interviews in 2025:
1. Programming Language Mastery
Choose one (C++, Java, Python) & master:
- Syntax & built-in functions
- Time & space complexity
- Object-oriented programming
- Recursion, Iterative logic
2. Data Structures
Understand how they work + when to use them:
- Arrays & Strings
- Linked Lists (Singly, Doubly)
- Stacks & Queues
- Hash Maps / Hash Tables
- Trees (Binary, BST, Trie)
- Graphs (Adjacency List/Matrix)
- Heaps & Priority Queues
3. Algorithms
Key to solving problems efficiently:
- Sorting & Searching (Binary Search, Merge/Quick Sort)
- Recursion & Backtracking
- Sliding Window, Two Pointers
- Greedy & Divide and Conquer
- Dynamic Programming (0/1 Knapsack, LIS, etc.)
- Graph Algorithms (DFS, BFS, Dijkstra’s, Topological Sort)
- Bit Manipulation
4. Problem Solving Practice
Use platforms like:
- LeetCode (Top 150/Blind 75)
- HackerRank / Codeforces
- InterviewBit / GFG
5. System Design (For 3+ years experience)
- High-level design (scalability, availability, latency)
- Components: Load Balancer, Database, Caching, Message Queues
- Design examples: URL Shortener, Instagram, Chat App
- Use tools like draw.io or Excalidraw to visualize designs
6. Behavioral + HR Round Prep
Prepare STAR-based answers for:
- "Tell me about yourself"
- "Biggest challenge you faced"
- "Why do you want to join us?"
- "Teamwork, leadership, conflict"
7. Resume & Portfolio
- Keep it ONE page
- Highlight impact, not tasks
- Add GitHub, LinkedIn, Portfolio links
- Projects that use real-world APIs or solve real problems
8. Mock Interviews & Feedback
- Practice with peers, mentors or platforms like Pramp / Interviewing.io
- Get feedback on approach, not just correctness
Tips:
- Stay consistent (1–2 hours daily)
- Focus on patterns, not just solutions
- Keep track of mistakes & revise weekly
- Rest before interviews – don’t cram
Tap ❤️ for more!

The journey finally reached its end on Day 130. What started as a commitment "until I get a job" has now come true and yes, I got one! 🙌
There were skipped days, struggles, and doubts, but looking back, it was truly a beautiful journey. 💙
> Completed @kirat_tw Web Dev Cohort 3
> Finished 71% of @striver_79 A2Z Sheet (and honestly, the questions felt easier compared to what I had prepared 😅)
> Worked on 5–6 projects, including my Cohort 3 project
> Now planning to dive into DevOps and wrap up the pending ones 🚀
Grateful for the growth, the consistency, and the lessons. On to the next chapter. 🌱✨

Coding Habits That Changed My Learning Speed
Small habits → Big impact 👇
> Code daily even 30 mins beats 3 hours once a week.
> Re-solve old problems without looking up solutions.
> Keep a “Bug Log” write every mistake you make.
> Track your consistency (Not your streak).
> Teach what you learn even in tweets or blog posts.
Good coders solve problems. Great coders learn from them.
