Hey there! I'm Arun, a dedicated Frontend Engineer with nearly 3 years of experience specializing in developing responsive, performant and scalable web applications.

Tech Skills - JavaScript (ES6+), TypeScript, React, Redux, Jest (unit testing), HTML5, CSS3.

I'm passionate about writing clean, efficient, and maintainable code following best practices and coding standards. I optimize web applications for performance and scalability, ensuring a smooth user experience across devices. Collaborating with cross-functional teams including designers, backend developers, and product managers is key to implementing user-friendly interfaces that meet business objectives.

Let's connect to explore opportunities where I can leverage my technical expertise to create impactful web experiences!

I Have Lost 25+ LPA offers
Only because I could not recognize the DSA pattern at the interview.
This is something that we all as SDEs face.

As working professionals, we often get stuck not because we lack knowledge but because we fail to recognize the patterns behind problems.

Also, due to a lack of practice.

Recently, I went through a resource shared by Meritshot, and honestly, it’s one of those quality guides that changes how you think, not just what you learn.

This Document is really going to help you walk into interviews feeling prepared, structured, and confident.

So, if you want to go beyond practice and get 1:1 mentorship, mock interviews, and placement-ready projects powered by AI, consider checking out Meritshot.

Check their complete program here: https://lnkd.in/gbEMif4X

In the program you’ll get:
 💡 A structured roadmap (DSA, System Design, LLD)
 💡 MAANG-level mentors & mock sessions
 💡 Real-world projects to prove your skills

DSA Patterns

6 months ago, I made my 2nd switch as an SDE-2 at a top PBC! 🎉

But a few months ago, I was staring at a rejection from Amazon Pay after 4 intense rounds when I tried to switch. 

Here’s how it went 👇

🔹 Round 0: Online Assessment (OA)
A frontend-heavy round with Vanilla JS: 
→ Build an Accordion Component, implement a Form UI with validation (Name, Email, Phone), 30+ behavioral questions based on Amazon’s Leadership Principles

🔹 Round 1: Frontend Coding + Leadership
Started with LPs:
• When did you go beyond your scope to improve the system?
• Talk about a time you had to stretch deadlines or compromise on tech decisions.

Then came technicals:
→ How does the JavaScript engine work?
→ Event Loop, Microtask Queue
→ CSR vs SSR (with real-world app examples)
→ Implemented an Autocomplete Component in React (without any helper tools)

🔹 Round 2: Frontend System Design
Design a video streaming app like Netflix from scratch. (Yes, it was hard.)

• Discussed architecture, state management, performance
• Followed by more LPs: handling mistakes, disagreement with manager, and learning curve

🔹 Round 3: Techno-Managerial (Hiring Manager Round)
Design a basic social app like Twitter or Facebook.

• Focused on Micro-Frontend Architecture
• What is Module Federation and how would you use it?
• SSR vs CSR: pros, cons, examples

In the end, I got rejected⛔

But every round taught me more than just code, it taught me how to communicate, adapt, & stay calm when the stakes are high.

So, if you're juggling a 9-5 while prepping for senior-level interviews like this, then checkout EVOLVE by Bosscoder Academy its a great place to start.

But I made it to 𝗧𝗲𝗸𝗶𝗼𝗻.  This is how I changed Everything 👇

I got rejected by companies I dreamed of.
It crushed my confidence, but not my willingness to grow. I didn’t give up.

-I worked on becoming better every day.
-I rebuilt my DSA and System Design concepts
-I improved my Communication
-I practiced mock interviews

But as a Frontend Developer, here’s what actually changed everything:

1/ I made my way to a deep understanding of JavaScript 
2/ I developed my React knowledge to an industry level — patterns, optimisation, state management.
3/ I developed real product-like projects, not apps, for my portfolio.
4/ I researched Frontend System Design and worked on architecture, scalability, performance.
5/ I strengthened my confidence through mock interviews and clear articulation.

And slowly, things shifted.

The rejections stopped. The callbacks started.
And soon.. I had offers from some of the top companies, and I decided to join Tekion.

This happened not because I was gifted but because I refused to stay the same version of myself.

If you're a working professional preparing for System Design, focus on these three. It changed everything for me.

So, if you want to go beyond practice and get mock interviews and placement-ready projects powered by AI, you can checkout Meritshot.

Senior-Level engineers don’t fail on coding skills. 
They fail on the fundamentals.

That’s exactly why I am sharing this Frontend Interview Questions doc, it focuses on the exact concepts interviewers dig into!

Big thanks to Bosscoder Academy for putting this together 🙌

#frontend #interviewquestions #javascript

I got rejected for a Senior-level role at Amazon after 4 intense rounds, even after 3 yrs in tech!

But this is the how the interview went 👇

🔹 Round 0: Online Assessment (OA)
→ Vanilla JS tasks: Accordion component + Form UI with validation (Name, Email, Phone)
→ 30+ behavioral questions based on Amazon’s Leadership Principles

🔹 Round 1: Coding + Leadership
→ LPs on ownership, deadlines, and tough trade-offs
→ JavaScript engine deep dive: Event Loop, Microtask Queue
→ CSR vs SSR with real-world examples
→ Built an Autocomplete Component in React (no helper tools)

🔹 Round 2: Frontend System Design
→ Design a video streaming app like Netflix
→ Talked architecture, state management, and performance optimization
→ More LPs on mistakes, disagreements, and learning curves

🔹 Round 3: Techno-Managerial (Hiring Manager)
→ Design a social app (Twitter/Facebook style)
→ Micro-Frontend Architecture, Module Federation
→ CSR vs SSR: trade-offs and use cases

Final result: Rejected ❌

But honestly… every round taught me more than just code.

Because at every senior interviewI sat in, I learned how to structure my answers, adapt under pressure, & balance technical depth with leadership clarity.

And if you’re a working SDE prepping for senior/leadership roles, consider trying the EVOLVE program for SDEs with 6+ YOE by Bosscoder Academy.

I kept dreaming of 30- 35 + LPA offer until….
I understood one thing

You cannot crack an SDE role at top PBCs with a proper roadmap.

Remember…
DSA teaches you how to solve problems under pressure.
System Design teaches you how to think like an engineer who can own real systems.

Even SDEs at service-based companies with 10+ years of experience fail to crack, because they think what helped them in service-based companies will help them in product-based based.

The Roadmap is only 50% same. Rest is completely different.

That’s exactly why Meritshot is hosting this masterclass to help working professionals have a clear roadmap.

System Design is not something you only worry about once you hit Senior SDE, trust me 👇

Because in reality, System Design shows up much earlier, and it’s a very imp. filter for any roles beyond SDE-2/3.

That’s why I’m sharing this “System Design Made Easy” doc 📄

Big thanks to Bosscoder Academy for curating this structured guide! 🙌

📌 Check their programs here →  bcalinks.com/Rr38sAy

Here’s what you’ll find inside the doc: 

→ Core concepts explained step by step (scalability, caching, load balancing, CAP theorem, databases)
→ Breakdowns of real-world system architectures
→ A 60-day roadmap designed to fit alongside a full-time job

If you’re a mid-to-senior SDE prepping for your next role, this doc can save you weeks of scattered prep and give you a roadmap that actually works.

And if you’re serious about growing into Sr. SDE roles at top PBCs, Bosscoder Academy’s EVOLVE program for SDEs with 6+ YOE is built exactly for this.

They’ve already helped 2200+ engineers crack top PBC roles, maybe you’re next?
